kankeL - The existing rear drum brake should give improved braking effort with increased hydraulic pressure. This is not possible with the existing master cylinder arrangement.
Installing twin brake master cylinders and a balance bar on the pedal box would allow brake bias to be adjusted to taste, and also offer the benefit of a larger master cylinder for the front brakes. Mulfab consider it possible to modify the existing pedal box and it could potentially become a Stage 2 upgrade
