Brake Booster issue question
i put on the brake booster and went to go for a quick drive to see if it fixed the problem. well now my pedal is real spongy and i have to press the pedal almost half way down before the brakes grab. I didnt remove any brake lines or anything. i simply un-bolted the master from the booster and swapped boosters. There are no visible leaks
Does this sound like air got in the system and they just need to be bled?
