So, bottom line, Consider your vacuum assist to the brake booster as an option to test if you've tried everything else because it's cheap and easy to try. Now wondering if my rebuilt brake booster from O'Reily's is good. Saw another thread where a guy said he had a bum rebuilt unit and had to get another.
I saw this as a way to check your brake booster: " Hold brake pedal in when you turn off car and pedal should not move for 30 seconds"; mine starts pushing back up almost immediately. Is that test legit? |
Not entirely. Even after you turn off the car the brake pedal has a bit of give in it. Pump it a couple times until it firms up and THEN hold it. There should be no give at all unless there's a fluid leak or vacuum leak in the booster.
