Ok so whole back story last year i changed my front manual drums to wilwood 4p disc with a hydroboost. So this system worked flawlessly absolutely no issue, till now. About 2 months ago the pedal started to feel mushy and at a stop light it felt like it lost pressure since the car will suddenly start going forward resulting in me having to put more pressure. thinking it was just air i drive it around for another 100 or so miles. So i did some suspension work and thought might as well bleed the system so i can get on it ..except the pedal got worse . Before it didnt sink to the floor but after i bled it, went straight down and barely caught on. at some point i was going down hill i couldnt stop so i pushed it a little harder and my rear drums locked up, but not my front disc. So ok i thought bad master cylinder. Well, i put in the master cylinder, new lines from master cylinder to prop valve, and bench bled the master as well as bleed all 4 brakes. guess what..still having the same issue :exclamation: , but the brakes got a little less scary and better! yay! -_-.. So now that leaves me to the prop valve. did that go bad? how can i check? do i need to bleed it? it has never been changed. If it isnt the prop valve then the pedal might need adjustments, since it catches on but, late. if that makes sense. I am no mechanic or expert in brakes, any ideas guys?
