handbrake

could still do with some help regarding the above, if any rally lads can assist? :d

I run a 6.25 iirc for my handbrake, I use to have 6.75 but found 6.25 is better option. What bias valve are you planning on using? I have willwood one in a corsa here. I don't have bias valve in my orange nova, never felt I have the need for it, although the works nova does so I might have a play and see what it does :p

ah cool, i take it you have T-pieced your rear lines into a single line through the handbrake and then split again at rear?

Well I run a pedal box so the out pipe from cylinder goes into car, through hand brake cylinder and then T's just behind rear seats then goes accross to each side then down through the floor to braided hose and caliper. Pretty simple setup really.

I'm not running a pedal box, just a 2 port Corsa B pedal and M/C so will be a single line through the car. May experiment without a bias valve and see what its like and fit one in after if need be

I'd run a pedal box if you can afford it. Means you can set how you like your brakes to work if that makes sense, plus if your pushing hard in a rally your pedal will pump up with a servo.

Only problem with pedal box on road rally car is that technicly your not aloud to be able to alter brakes from drivers seat. I still have my adjustment nob on the dash infront of me and have never been pulled up on it. Although my mate has a couple of times and had to disconnect adjuster :( pain in the **** if running late through scrut

I know exactly what you mean, I may see if a Corsa one comes up cheap enough...just starts putting the cost of the build up!! I may fit standard MC for now then look into pedal boxes further down the line once the car is built. As for the adjuster knob i reckon I will fit that in the engine bay,

Good plan. A friend of mine takes the vacum pipe of his servo on his proton as he can't afford pedal box but breaks were pumping up lol legend
