The brakes of a car chatter when they are applied. Which of the following could cause this problem? Technician A says the dust boot of a caliper should be removed and a large screwdriver used to pry the piston out of it's bore. Technician B says air pressure should be injected into the brake line hole to force the piston out of the brake caliper. The brake warning light on the dash stays on all the time. Which of the following could be the cause of the problem? The front of the car equipped with disc brakes in the front and drum brakes in the rear, grab quickly as light pressure is applied to the brake pedal, which of the following could be the cause of the problem?
