Step 30 - Slowly press the brake pedal down, then, slowly allow the pedal to return to its original position. This will bring the brake pads to the rotor, initiating contact.


Press Brake Pedal

After completing the job check the brake pedal operation. Because the system was never opened, brake bleeding should not be necessary, but if the pedal is spongy, bleed the brake system. Never operate a vehicle without normal brake pedal operation. While driving the vehicle, listen for strange noises as this is an indication of a problem in which repairs will need to be performed. Inspect brake fluid levels in the brake master cylinder. Brake pad design configuration may vary slightly, but the concept is the same.


Helpful Information

A rear caliper reset tool is necessary for parking brake integrated systems. The reset tool screws the piston back into the caliper. These calipers cannot be compressed with a clamping tool, it can only be reset with the reset tool. A locator slot is used on the inboard piston, which is fitted into a peg located on the backing plate of the pad. Rear disc brake pads offer improved performance and are not affected by moisture like conventional brake shoes.

Common Problems

  • Brake pads wear down making a grinding noise.
  • Caliper slides lock up, not allowing the caliper move causing premature pad wear.
  • Inferior parts squeak, grumble and prematurely wear.
