Today i noticed that pedal gets hard after the engine is turned off.
I looked around and my brake booster is making a vaccuum leak sound. Replaced the hose
from booster to intake manifold with the valve in the middle. Did not fix issue. I think air is entering the booster somewhere.
Brakes feel mostly normal, might be some very slight pedal sink at idle. Brakes still have good stop power but I think it could be better. I am not leaking fluid anywhere. Master cylinder seems ok, needs new fluid bled.
Is this the brake booster going out, or is there something else I am not seeing?
