MK5RST

fitted cossie brakes all round to my MK5, with the same master cylinder ad the old brakes, the rear brakes are a bit keen, as in they lock up before the fronts..... Lethal what should the percentage be between the 2 brakes, 100% being the fronts, where should the rears be?? around 70%???? Any info will be good, regards. pete

generally ya need about 70 to 80% pressure to the front if you whack em on hard. otherwise 60 to 70% normally. i'm guessing you dont want the latter. otherwise you wouldnt have upgraded.
if you want 70/30, f/r... 30 is less than half the pressure of 70. (obviously)
so if as you say, 100% on the front, you'd be looking at about 35% on the rear.

MK5RST

right, i upgraded because the 1.6 std brakes and drums werent any good for a 170bhp rst motor and ive just ordered a cam kit and have got my front mount cooler to go on to so opting for 200bhp but want to get brakes right beforehand, ive ordered gaz coilovers too, im trying to get a good all round car...

pee vee

did the same mod on mine mate
but i had Fitted RS2k/xr31-130spec rear disc brakes.
and it was never a problem on mine.

MK5RST

yeah, those rear brakes are slightly smaller and are made for that setup, i wanted cossie brakes all round and i got em cheap

choppa

sensible man, brakes first. 200hp should be fun.

MK5RST

well the car wieghs nothing, dashboard, 2 cobra seats and a full SD roll cage so i cant afford for the back brakes to be locking up mid corner Pic here..... Not everyone,s cup of tea i know.....

choppa

whatever floats ya boat mate... i'd have one if i had the money for a new car...! couldnt afford the mods youve done though

choppa

nice wheels

MK5RST

well the shell cost me just short of £200 and the cossie wings and skirts about £300 SD cage £200 seats £200, brakes £100 and rs running gear + all other bits inc cams, chips ect about £700 so it aint MEGA bucks

JamboRS

get a bias valve and you can set the brakes to any level

MK5RST
