Repair Instructions

If the inspection shows that the brake pads are worn or the rotors are damaged, follow these steps:

Step 1: Remove the Brake Caliper

  1. Loosen the Caliper Bolts:

    • Use the socket set to remove the caliper bolts securing the caliper to the bracket.

  2. Remove the Caliper:

    • Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it to prevent strain on the brake line.

Step 2: Replace Brake Pads

  1. Remove Old Brake Pads:

    • Slide the old brake pads out of the caliper bracket.

  2. Install New Brake Pads:

    • Apply a thin layer of brake grease to the backing plates of the new pads (if applicable).
    • Insert the new pads into the caliper bracket.

Step 3: Compress the Caliper Piston

  1. Use C-Clamp or Brake Tool:
    • Place the old brake pad against the caliper piston and use a C-clamp to gently compress the piston back into the caliper. This step is necessary to create enough space for the new, thicker pads.

Step 4: Reinstall the Brake Caliper

  1. Slide the Caliper Back:

    • Position the caliper back over the new brake pads and rotor.

  2. Tighten Caliper Bolts:

    • Reinstall and tighten the caliper bolts to the manufacturer’s specified torque.

Step 5: Reinstall Wheel

  1. Mount the Wheel:

    • Place the wheel back onto the hub and hand-tighten the lug nuts.

  2. Lower the Vehicle:

    • Carefully lower the vehicle off the jack stands.

  3. Tighten Lug Nuts:

    • Use the torque wrench to tighten the lug nuts to the manufacturer’s specified torque settings.
Final Steps

  1. Test the Brakes:

    • Before driving, pump the brake pedal a few times to ensure the caliper piston is seated and the brake system is operational.

  2. Check for Squeaking:

    • Drive the vehicle in a safe area and test the brakes. Listen for any remaining squeaking or unusual noises.

  3. Inspect:

    • After a short drive, perform a final check of the brake components to ensure everything is secure and functioning properly.

If the squeaking persists after replacing the pads and performing the above checks, consult a professional for further diagnosis, as it may indicate issues with the rotor surface or other components of the brake system.
