...noise temporarily if the car is sitting a few days. After you hit the brake a few times it quiets down. I took the drums off and the shoes seem to have plenty meat on them. I didn't see anything wrong . The brake fluid level is good. I was wondering if the line pressure is weak .... or ... cylinders are weak ...
What could be causing this to happen ????
