Strange situation going on that I've never seen myself.... a couple weeks ago I installed a quick performance 9" into my El Camino with disc brakes and ebrake. While bleeding the brakes the master let go, so installed a new one. Haven't change the proportioning valve and the brakes seem to work fine. That is until I go for a drive and 10 15 20 minutes later the brakes lock up and stay that way. The only way to free them up is to open the bleeder, and not all 4 wheels, sometimes front sometimes back. Maybe its the stock disc/drum proportioning valve screwing with me? Idk, driving me nuts thou
