Pops are often sticking calipers. If the rear brakes are acting differently from one another, it is not the ppv.

Just to ask a stupid question, the e-brake is off, correct. and it's slack?

 

But what would cause these problems with the rest of the wheels. I can understand the sticking caliper but I dont know why the pedal would only go have way down with the rest of the wheels.

E-brake is not set and it has slack in it.

WTF Can This Be?????

 

Explain, step by step, exactly how you are bleeding. Are you trying to this by yourself, or do you have help?

When I bleed, 2 people, I use a plastic peanut butter jar with a vacuum hose going from the bleeder into the jar with the the hose submerged in fluid. This way I can see when the bubbles stop coming out of each wheel and eliminates the chance of air being drawn back in.
