I'm Awesome
Well long story short I have put all new brake lines on the rear of my truck and bled them. All the front brakes are brand new and have been previously bled. When you push the pedal down as if you were bleeding the brakes, it never gets real stiff, but sometimes it gets somewhat hard. When you released the bleeder screw on the back brakes, the pedal does not go down like it normally does on anything else I have done. There is good steady stream of fluid coming out of the screws. The leaks that the truck had on the rear have been fixed. It is not leaking brake fluid anywhere that I am aware of. So anyways.. lol when the truck is running, you have to pump the brakes up to really get that much of a pedal. They still work for the front decent, but the back ones take alot of pumping of the pedal to even get it to begin to grab the wheel. I am not sure if it is the master cylinder/ brake booster/ or proportioning valve going bad. I have heard a brake booster leak because they loose vacuum and mess with the motor idle, but not the case here. any help I would appreciate it.
