Introduced specifically for production cars, BG Developments has developed a balance bar pedal box assembly that can be fitted as a direct replacement for either an existing master cylinder or servo unit. No modifications whatsoever are required to the bulkhead or brake pedal.

When it is felt that servo assistance is required, the pedal box can be fitted directly to the servo unit, the mounting plate replacing the standard master cylinder-mounting flange. If servo assistance is not required, for example if group A type brakes have been fitted, then the pedal box end plate would be a direct replacement for the existing servo unit, and the assembly bolted to the bulkhead and connected to the standard pedal, with no modifications required.

The advantage to using a balance bar to operate the brake system is that the master cylinder sizes can be tailored to suit the front to rear balance required and the caliper piston diameters. Final balance adjustments can then be carried out using the balance bar either on the bar itself, or remotely via a dash mounted cable adjuster.

A further advantage to using this type of system is that in most instances it does away with the need to fit expensive proportioning valves, to control the rear brake pressure.
