Adjustable Dual Circuit Brake Balance box

Prices are exclusive of VAT.

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 adjusted easily. 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! (as shown in photo)

This kit further permits master cylinder size to be optimised, which is especially important if non-standard brakes are being used. Servos may also be removed, which as well as saving cost on replacement items allows for unservoed brakes – a particular bonus for pedal feel, so crucial for racing.

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


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

As used on the Alfaholics Sprint GT racer & Max's GTA Replica
