SOLVED Brake Pedal Stiff as Hell and No Brakes

As I have been dealing with my hesitation issue now I have a whole new problem. Went to hit brakes brake pedal would not move no breaks at all. Hissing noise came from brake pedal area when I Turned it off and Pressing down at first. With engine running I press brake pedal in park and motor starts to run like crap. When i turned the Engine Off I hit Pedal won’t go Down far at all but No Hissing.

 

Sounds like you have a bad vacuum leak. Could be the power brake booster itself has failed, or a vacuum hose has cracked or come off the engine somewhere. Might want to check the plastic check valve on the brake booster too.

 

Check Valve seems to be in Working Order.

 

Loud hiss and hard pedal is very sure sign of booster failure. I'd bet my .02$ on it.

 

Yep already have a New Booster. Now to install. 1st time dong this job

 

New Booster in Problem Solved. Not hard and left Brake lines connected.

 

Thanks for following up! This will surely help someone searching with the same problem.

I would add SOLVED to the thread title, go near top of page and click on "thread tools" and "edit title"

 

I just developed this hissing noise on my 01. Where did you get the Booster from?

Cool! Thanks

 

Man this helped me. I have been hesitant because everyone speaks of spongy brakes when talking about brake boosters. Mine are hard and have a hissing sound. Not to mention , my vehicle travels and brakes don't bite. Vacuum lines are all good as well as rotors and pads. Started after bleeding . I think I caused it by over- bleeding. May have messed up my diaphragm in my booster according to older thread I read. Ordering booster now.
