Brakes & brake parts for performance 105 series Alfa Romeo

Complete set of new brake calipers, sport grooved discs, Ferodo Ds2500 brake pads, fitting pins and braided steel brake flexi hoses for all 105/115 series Alfa Romeos from 1968. Available for both 1300/1600 ATE brakes with a 76mm front caliper bolt spacing or 1750/2000 ATE brakes with a 89mm front caliper bolt spacing.

New sports brake package for all 105/115 series cars, developed by Alfaholics in our workshops and tested on our cars to produce a high performance sports braking package suitable for fast road, rally and trackday use. The kit is compatible with your current brake master cylinder/servo setup meaning there is no need for any complex re-plumbing work to be carried out. The 4-pot front brakes give beautiful quality lightweight billet aluminium calipers with large pads & vented 280mm discs to keep brake temperatures under control under hard use, whilst the billet aluminium rear calipers with sports rear discs give improved performance and reduced weight over standard parts. The kit comes complete with braided flexible hoses for improved brake pedal travel and a bias limiting valve to fit in the rear brake line to ensure the front to rear bias can be set correctly. Kit supplied with Ferodo performance brake pads for fast road and trackday use with servo assisted brakes. Please choose from 1300/1600 (76mm) or 1750/2000 (89mm) dependant on your front upright caliper bolt spacing. Kit compatible for all cars with ‘late’ ATE brakes (1967/8 onwards) as standard which are identifiable by 1 piece uprights and front wheel studs fitted in the discs, not directly into the hubs.

Following the success of our full GTA-R suspension package, we have introduced the equivalent full brake package as fitted to our GTA-R builds. We run all our top specification road and track cars with un-servo assisted brakes and our dual circuit bias adjustable pedal box to give the ultime levels of feel and modulation in the brakes, not possible with servo assisted systems.  This packageconsists of:-

Choice of Alfaholics Billet aluminium bias adjustable pedal box (either RHD, floor pedal LHD or hanging pedal LHD)

• Alfaholics 6-pot or 4-pot front brake kit
• Alfaholics billet aluminium rear calipers
• Sport rear discs
• Alfaholics Braided brake line – set of 3
• Alfaholics front caliper banjo brake lines
• Ferodo DS performance brake pads for race or road/track day application.

Upgrade this kit to our lightweight ‘Superleggera’ version of 6-pot kit and rear calipers which represents a 1.5KG weight saving in both un-sprung and rotational weight over the standard 6-pot kit!

Exclusively designed and manufactured for Alfaholics, this kit represents the ultimate 4-pot brake upgrade for 105 series/ Alfa Romeo!

The kit is a result of an extensive development programme consisting of thousands of miles of both circuit and fast road use on our own cars. We have used this experience and data to evolve our existing offering and produce an all-new 4-pot kit incorporating significant improvements in caliper design, as well as machining quality.

By designing a bespoke caliper for the 105 series, we have been able to eliminate the compromises associated with a generic ‘off the shelf’ item. For example, we have been able to enlarge the caliper where necessary and at the same time increase the number of cross bolts from 5 to 8 in total. These two key features have dramatically increased the rigidity of the caliper, thereby improving pedal feel and reducing pedal travel. This has also resulted in considerably increased stopping power! Mounting brackets are available for either small uprights (1300/1600) or large uprights (1750/2000), to ensure that this kit fits all 105 series cars. The new caliper fits inside both the Alfaholics 6×14” GTA Strada and the Alfaholics 7×15″ GTA Veloce wheels.

In developing this new caliper, we have chosen not to use dust seals to allow the caliper to withstand higher brake temperatures. Max has run his GTA Replica using calipers without dust seals for 3 years and some 20,000 miles with no adverse effects. In fact, having recently stripped the calipers down to their component parts, they are still as new! The reality is that for mainly fair weather use, dust seals are not necessary as the calipers are not exposed to winter road treatments often enough to need them. However, for customers who wish to have dust seals, we shall continue to stock our previous production.

The kit is supplied complete with all bolts, lock nuts, washers and hydraulic fittings, ready to fit directly to your car with no modifications.

This kit is compatible with standard Alfa Romeo master cylinder & servo systems as well as aftermarket master cylinder systems such as the Alfaholics single & dual circuit master cylinder conversions.

Exclusively designed and manufactured for Alfaholics, this kit represents the ultimate braking for extreme trackday & full race 105 series cars!

This kit has been prototyped and perfected over the last 2 seasons on the Alfaholics 2.0 Sprint GT Racer to provide the very highest braking power and consistency under the most strenuous race conditions.

The rotor is 20mm larger in diameter than our 4-pot kit, increasing the total surface area by 20%, and the width is increased by 8%. This results in even higher braking force, modulation and improved heat dissipation. During development we were not happy with the weight of normal off the shelf rotors in this larger size, so we had our own rotors designed and manufactured. The results are a 25% weight saving over similar off the shelf rotors and with further improved cooling characteristics.

The caliper features 2 smaller leading pistons and a larger trailing piston; this ensures zero taper wear occurs when the elevated temperatures seen in racing leave the pads most susceptible to taper wear. By using 6 pistons per caliper we have been able to increase the pad surface area by 25% from that used in our 4-pot kit, this not only results in increased stopping power and longer pad life but also helps to control pad temperatures under full race conditions. The caliper has been designed to be as large as possible in certain critical areas to maximise rigidity and has been designed specifically to fit inside the Alfaholics 7×15” GTA wheel range (or larger).

This kit, however, is not only for full race cars, it is also the ultimate solution for trackday cars looking for the very best in non-servoed braking. The Alfaholics 6-Pot brake kit is only compatible with non-original master cylinder systems with optimised bore diameters.

Following the huge success of our 6-pot brake kit, we have designed this fabulous new lightweight version which represents a 1.5KG weight saving in both un-sprung and rotational weight over the standard 6-pot kit! It features lightened calipers, lightened mounting brackets and lightened disc mounting bells. The kit has been extensively tested over the 2013-14 winter and spring with many road and track miles on Andrew’s Alfaholics TI Super-R. As now fitted to all the Alfaholics GTA-R 290 builds.

1.5KG weight saving over standard caliper, each! Exclusively designed and manufactured for Alfaholics as a direct replacement for the original and very heavy iron ATE caliper. CNC machined from billet aluminium and finished in hard anodising to match our front 4-pot and 6-pot calipers. They also feature stainless steel pistons with ultra high temperature seals.

These calipers with modern piston & seal design do not suffer the same piston retraction issues that affect original ATE calipers. As a result, the brake pedal length is dramatically improved thereby giving increased confidence under heavy braking and also eliminates the inconsistent characteristics caused by ‘pad knockback’.

Following the huge success of our billet aluminium rear caliper upgrade, we have designed this fabulous new lightweight version with scalloping to remove unnecessary material which represents a 0.4KG weight saving in unsprung weight over our existing aluminium calipers! The kit has been extensively tested over the 2013-14 winter and spring with many road and track miles on Andrew’s Alfaholics TI Super-R. As now fitted to the Alfaholics GTA-R 290 builds.

As used on all our GTA-R builds. Box CNC machined from billet aircraft grade aluminium, giving a superb look to the kit!

Alfaholics production. To fit right hand drive only. This box directly replaces the standard Alfa / reproduction brake master cylinder whether it is a single or dual circuit set up. It bolts onto the outside of the chassis leg using the standard fitment points, no modification is necessary.

It uses a pair of Girling race brake master cylinders with an adjustable balance bar allowing the front to rear brake bias to be very finely adjusted. A remote bias adjuster cable can be screwed onto the end of the bar to allow the bias to be adjusted from the cockpit whilst driving, great for trackday and race use!

Because this kit uses a pair of race master cylinders, we are able to optimise the bore diameters to allow the servos to be removed whilst still having optimum power. As a result of not using the servos you get a dramatic improvement in the feel of the brakes allowing far better modulation of brake pressure and thus less chance of locking the wheels under heavy braking. The added bonus of using this system is a significant cost saving by not having to use expensive servos and reproduction Alfa master cylinders. Indeed this pedal box is cheaper to fit than a reproduction RHD dual circuit master cylinder and a pair of servos! As a result people in the process of building fast road/trackday or race cars from scratch have the unique opportunity to simultaneously improve the brake system dramatically AND save money!

A spherical joint is fitted in the front of the box where the pedal rod enters the box to ensure perfect free movement of rod.

Kit comes complete with master cylinders, banjos for hydraulic fittings, brake rod, balance bar, spherical bearing, lid and bolts.

As used on all Alfaholics performance builds and GTA-Rs.

Premium quality Alfaholics production! This kit is an adaptation of our hugely successful RHD dual circuit balance box, now designed to fit LHD 105 series cars with floor mounted pedals. As used on all our GTA-R builds. Box CNC machined from billet aircraft grade aluminium, giving a superb look to the kit!

This box replaces the standard Alfa-type brake master cylinder, whether it is a European single circuit or a USA dual circuit system. It bolts to the gearbox cross-member and is a simple installation. As shown in the photos, it fits perfectly and is tucked up neatly out of the way. It can also be used in conjunction with standard exhaust brackets and is compatible with the Alfaholics stainless steel sports exhaust system. This system is perfectly suited for both fast road and track day cars as well as full race cars

It uses a pair of high-quality Girling race brake master cylinders with an adjustable balance bar, allowing the front to rear brake bias to be adjusted. A remote bias adjuster cable can be screwed onto the end of the bar allowing the bias to be fine-tuned from the cockpit.

By using race master cylinders, we have been able to match the bore diameter of the cylinders to the calipers, thereby permitting the servos to be removed while also maintaining excellent braking power. By removing the servos, pedal feel is dramatically improved and it is easier to modulate the brake pressure and therefore minimise wheel locking under heavy braking. The kit is supplied with the optimum sized master cylinders depending on whether the car is fitted with Dunlop, ATE, 4 pot or 6 pot brakes.

A spherical joint is fitted in the front of the box where the pedal rod enters the box to ensure free movement of the actuation rod.

The balance box is supplied complete with master cylinders, banjos for hydraulic fittings, brake rod, balance bar, spherical bearing, lid and bolts.

As used on all our GTA-R builds, premium quality Alfaholics production!

Following the success of our floor pedal brake balance box systems, we have developed this superb kit for late Left Hand Drive cars with hanging pedals. It fits directly with no modifications required, bolting directly to the aluminium pedal casting where the servo used to fit.

Being a non-servo system, it gives you unrivalled brake feel and the internal brake bias adjuster allows you to easily and accurately set the front to rear bias.

We have also integrated the clutch master cylinder into the box, which connects directly to the original Alfa clutch actuation arm and thus simultaneously results in a premium race quality clutch master cylinder upgrade. The system is compatible with both original Alfa steel pedals as well as our Alfaholics billet aluminium pedal set.

3 race reservoirs, laser cut aluminium mounting bracket and a set of race quality stainless steel braided feed lines (with a black protective coating) to connect directly to race master cylinders, as used on our GTA-Rs. To be used in conjunction with our GTA-R brake package/dual circuit brake pedal box and our Girling clutch master cylinder conversion.

For fitment with the Alfaholics RHD dual circuit pedal box, all you need for plumbing the pedal box into your RHD car. 4 line kit – front feed line from front master cylinder to t-piece, left & right feeds from t-piece to inner wing fixing point, rear feed line from rear master cylinder to fitting point under rear seat pan.

Brake bias adjuster to allow bias adjustment from inside the car. This is a neat lightweight cockpit adjuster cable with a positive half turn stop and is supplied with a fitting kit. As standard supplied with a 6’ cable, different lengths available to order. Designed to be compatible with the balance bar used in all of our adjustable dual circuit brake balance box’s.

Alfaholics production. To fit RHD only. Convert away from reproduction Alfa type brake master cylinder with this kit which enables the use of premium quality Girling race master cylinder. These Girling master cylinders are extremely reliable and simple to re-rubber should you wish to do so in the future. They will also naturally be available for decades to come, unlike the reproduction Alfa unit.

It enables people experimenting with different caliper setups to easily and economically change the master cylinder piston diameter by fitting 1 of the many different master cylinders bores available in this format. This enables brake pedal length and power to be adjusted to match caliper piston volume. This kit is also essential for people wanting to remove their servo to improve pedal feel and power modulation

Kit comprises laser cut and powder coated bracket, master cylinder, adapter rod to fit onto original pedal clevis rod and hard line fittings to enable easy plumbing.

“the brakes worked very well – I tested them a lot and it feels easy to modulate them and predict when locking is likely to happen – much more feel than with the servo” Richard Merrell commenting on fitting this kit to his GTA Replica

Alfaholics production. Fit this superb kit to transform the capabilities of your rally/autocross car.

This kit plumbs directly into the existing rear brake line, so no complex and heavy mechanisms are required. It fits to your original handbrake lever, with the ratchet removed. As you pull the lever, the rear line is pressurised from the point of the in line race master cylinder. The rear wheels are locked in isolation from the rest of the brake system. Letting go of the lever, releases the pressure and the rear brakes unlock. If foot pressure is applied to the brake pedal, the pressure coming down the rear line forces the handbrake to release for extra security.

The bracket mounts directly to the existing centre propshaft support so fits all 105 models with the later, stronger centre support mount. Clients whose cars have early centre supports (i.e. small propshaft cars) can fit this kit with a simple conversion to the later HD centre mount, a worthwhile modification, we feel, for any competition car with an early propshaft mount.

Kit includes a stainless steel braided pressure line to run from the cylinder to the mounting point under the rear seat pan. To fit RHD or LHD cars. (Handbrake clevis not included, re-use your old item).

Convert away from clumsy and often problematic Alfa fluid reservoirs with these superb race items. Neat dimensions to store fluid for individual brake circuits & clutch. Features 7/16 UNF fitting which allows use of either stainless braided feed lines or direct copper pipe fitting.

Superb quality cap and heavy duty hydraulic fitting ensure you will never have reservoir problems again! Also superb for converting mechanical clutch cars to hydraulic system.

Available in standard size, as photographed, for individual front or rear brake systems or clutch systems and in tall size for combined (single) circuit brake systems.

Laser cut and jig bent bracket for mounting 3 Girling reservoirs equally on firewall, as used on all Alfaholics GTA-R builds. Can be modified down for mounting only 2 reservoirs if required.

Set of four reproduction vented brake disc backing plates to suit large front calipers. Made in Aluminium and powder coated in black.

Cross-drilled & grooved sports discs for improved brake dust & gas clearance. Available for both 1300/1600 & 1750/2000 front brake setup and rear brake. Please select.
