Adjustable bias pedal boxes are the perfect solution to control the amount of braking required on each axle to achieve the perfect balance in braking by giving you full control of your desired settings front to back (unlike a bias valve which is not the complete solution as it is usually only capable of reduce the power of the rear brakes). We offer a large range of Compbrake bias pedal boxes to suit rally and racing saloons as well as single seaters.
 
Compbrake offers the widest range of competition bias pedal boxes, individually made in the UK. Which are supplied fully complete with a choice of Master cylinders (0.625, 0.7 or 0.75) and spherical bearing race balance bar. Each individual design has proven to withstand the trials of motorsport and offer fine adjustment either fixed or remotely adjusted via our cockpit mounted race click adjuster.
 
All our bias pedal boxes can be adjusted via a controller from the cock pit and come supplied with a spherical bearing race balance bar and master cylinders to suit each vehicles application. Each bias pedal box is designed in house and tested before despatch ensuring that the installation is a direct fit.

Some of our bias pedal boxes require the supply of the original pedal box for modification. Some pedal boxes are a direct fit in the foot well and replace the original pedal box assembly were others are specially designed to fit by removing the servo unit and installing the bias pedal box to locate on the original servo fixings and connect to the pedals as the original design.


All adjustable bias pedal boxes can be supplied with reservoirs and braided feed pipes with a choice of Girling master cylinders of alternatives depending on application. We can provide you with technical details and support on the adjustment and set up of your bias pedal box.
