I just replaced my clutch master cylinder and in doing so removed the hose from the brake booster. After putting everything back together my brakes were real stiff. I then bled all 4 brakes and my pedal is still real stiff. I seem to have to apply a lot more pressure to the pedal to stop but it does stop. Is this normal or could I have damaged the brake booster.

 

Did you put the hose on the same way it came off? There is a check valve inside that hose. Its there to keep air going one way when the brake booster gets vacuum pressure from the engine.

 

Take a look at this thread that I posted on.
I hope this helps some.

Yeah, make sure the check valve is on the right way. It will only let the air go one way. There should be an arrow that says "To Engine" or "Engine" on it.

If that doesn't help take a look at this thread that I posted on earlier.
I hope this helps some.

Thanks dudes, the hose was on backwards. Problem solved.
