#1. The brake pedal on a vehicle with power-assisted disc/drum brakes moves slowly to the floor during braking. Which of these could be the cause?
#2. On a vehicle with disc/drum brakes, the front brakes grab quickly when light pedal pressure is applied. This could be caused by a failed:
#3. On a vehicle with single piston, floating caliper disc brakes, the brake pad against the piston is badly worn. The other brake pad is only slightly worn. Technician A says that too much rotor runout could be the cause. Technician B says that a frozen caliper piston could be the cause. Who is right?
#4. When the brakes are applied, a vibration comes from the front of a vehicle with a disc/drum system. Which of these could be the cause?
