Brake Booster question LEAKING!
I have changed out the piping and know its not that. My brake booster feels like its leaking from the firewall. Like where the brake booster meets the firewall. I have pressure but it leaks, so when i brake hardm, i lose pressure at the end of braking. And when i turn off my car u can hear it "hisssssssssssssss". Any suggestions of what is wrong is great. thanks.

Re: Brake Booster question LEAKING! (MiX)
You might have a leaking diaphragm.
get a vaccum pump and attach it to the booster directly (do not leave the check valve installed) and see if it holds vaccum if not then its leaking and bad.

Re: (dogfood)
well when i brake it seems alright when i first start to brake but when i brake hard it gets mushy then hard at the end. and it sounds like my brakes lock up, But then again i dont have abs so they would lock up. But it makes weird sound. Like i can be in park and brake and i heard werid noises. But i just want to make the hissing sound stop when i kill the motor.
