Brakes

[Graham]

Ok so not stictly in the remit of the engines forum but i thought i'd start here...

im looking to upgrade the brakes and psssibly the pedal box on the racer,
i've gone for the biggest disk size that i can get away with weight penalty size 299-300mm but how do i work out what caliper is it just the most pistons and piggest pad area i can get in the wheel? and with the widest disk?


ALso if i change the pedal box and go to twin master cylinder how do i work out the master cylinder piston size and if i need to source twin remote master cylinders or if i can do without?


cheers

I was really hoping to be able to go floor mounted but as you say there is no space to do it. the real problem i have is that the pedal box is so poorly mounted it moves around to much loosing feel. i also wanted to run the twin cylinders for better adjustment control.

Ap do do a very nice looking 3 pedal box with pull rather than push cylinders but i hate to ask how much as a fully specced up Tilton 3 pedal unit id about 650..

SO it looks like finding some way to stiffen the pedal mount on the bulk head for now... and adding a better proportioning valve

As for brakes themselves im currently looking at hispec racing 132-6 ( 6pot) calipers and 299X32 performance friction disks and pads, i just need to work on the offset to clear the top wichbones.
