When replacing the rear brake pads on a vehicle with an electric parking brake what additional step is required before removing the caliper?
To remove the rear brake pads, you need to compress the caliper piston first. You won’t be able to do this if parking brake is set. You would be “fighting” with the actuators to compress the pistons. If you try to compress the pistons while the actuators are pushing them out, you may cause damage.
Do you always have to turn rotors when replacing brake pads?
The quick and easy answer to the question is “no.” However, this answer is relative to the reason why the pads are being replaced. If the disc brake system has been functioning properly and the pads are being replaced due to wear, you might forgo turning the rotors.
What causes a brake caliper piston to retract away from the disc after brake application?
Fluid pressure inside the caliper pushes one or more pistons outward to apply the brake. When the brake pedal is released, hydraulic pressure drops and the calipers loosen their grip. When the brakes are released, the piston seals retract the pistons, allowing the rotor runout to kick the pads away from the rotors.
