Ok So a while ago, as stated before,my mom made me go to the local mechanic shop to fix my brakes and told me that my proportioning valve and master were out. So i just replaced the master myself with a cheapo $25 one. Problem is that ive bleed the system for like 2 hours straight and now with the new master, the car doesn't lockup tires when i slam the brakes like it used too, and i have to push down pretty far to get the brakes going and its not very good either. Should i replace the PP valve with another one or try a different master cylinder? I think the quality of the master might be bad as well..What do you guys think? I tested the booster and it checks out and no brake fluid leaks anywhere else....Please help I know this sounds weird but I have a date with the girl i like in a few days and i dont wanna crash my firebird with her in it!!
