I had a previous post about my brakes not working, just had a question tho, that makes me think that i just have alot of air in the system. With the car OFF, and i push the brake, it seems like the pedal gets progressively harder (but not enough that i cant push it to the floor), and then if i let it go for a min its back to being all mushy and stuff and i have to pump the brake again. Could this help anyone diagnose this problem?

 

im going through the same thing replace the booster
