So i was in race and when reached the finish line Suddenly the brake pedal went to the floor.took my foot off and pressed it again it was find. And later searched for the issue I did not find any problem and There is no leakage of oil from the brake line , only i see the leakage from the back of wilwood master cylinder .

NOTE:I Cancel brake booster only i use wilwood master cylinder .

i know all the "replacement" masters that are in the booster less "kits" wilwood only recommends to be ran on 2 wheels, and not all 4

you may want to call them and ask if the one you have is idea for your setup

chasebays sells the wilwoods all the time they said they have never had a problem.Recently I bought one just havent tried it yet hope I dont have any problems

MrParks

Wilwoods have a tendency to.do this.if you don't bleed the.unit.properly I would rebleed the.unit.and make.sure the cap for the res is tight.and sealed. The masters they sell ate not open normally like oem ones. It uses a LIL vaccum pressure to re fill the master under pedal pressure. Next time before the pass pump the pedal a couple times to insure there is.pressure.

MrParks

Vacuum bleeding would.be ideal
