Setting up a pedal box
Turbo Mini Forums

Can anyone help me with regards to setting up the brake bias on pedal box I have a titon pedal box.

I'm basically trying to find out if there's a need for an inline brake proportioning/limiting valve? I'm a bit new to all this, the main reason I wanted the pedal box and master cylinders inside is to free up some space in the engine bay. The pedal box I have comes with a knob for adjusting the brake bias.. Is this effectively the same as a brake proportioning/limiting valve?

i'm going to be running 7.5" front discs with alloy 4pots and standard rear brakes but with minifins and verto RTS clutch. The master cylinder sizes I have are:
Front 5/8 .625
Rear and clutch 3/4 .725
Which I was advised by the person I bought the pedal box from.

All I want is the brake balance to be the same as a standard mini, with the master cylinder sizes I have can I achieve this? And without the need for a brake proportioning/limiting valve?

Thanks in advance!

The only way you'll really get it set up correctly is through physical testing and adjustment which is a bit dangerous on the road if you don't know what you're doing.

The knob adjusts the propotion of pedal force transfered to each master cylinder by adjusting the master cylinder positions on the bar. Set the bar in the box so that it is perpindicular to the master cylinders and then start back from there. The rears will lock in this position as the brake bias will be set 50:50 (F:R). Now adjust the knob until the rears only just lock up as the fronts do.

On a road car thit should be easy to find a safe ball park setting but it begs the question of why you've bothered to go to this much trouble to simply retain the standard bias settings.
