Q:IS THERE A WAY TO CHECK THE POWER BOOSTER? THE MASTER CYLINDER HAS BEEN REPLACED AND EACH WHEEL CYLINDER HAS BEEN BLED BUT THE PEDAL GOES DOWN TO THE FLOOR. THIS HAPPENS WNEN THE MOTOR IS RUNNING. BUT WITHOUT THE ENGINE RUNNING THE PRESSURE IN THE FOOT PEDAL COMES UP. COULD IT BE THE POWER BOOSTER//// THANKS
A:An easy way to check the power booster is pump it up with the engine off. Once it gets stiff start the car the pedal should go down a little. If it goes to the floor the booster is bad. If it stays up the booster is bad.
