Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads
- Check the thickness of the brake pads; replace if below 3mm.
Replace Brake Pads
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Insert new brake pads into the bracket, ensuring proper alignment.
- Compress the caliper piston using a C-clamp or brake tool to fit over the new pads.
- Reinstall the caliper and tighten the caliper bolts to the manufacturer's torque specifications (typically 25-35 ft-lbs).

5. Inspect and Replace Rotors (if necessary)

Inspect Rotors
- Measure rotor thickness to ensure it meets specifications; replace if below minimum thickness.
Replace Rotors
- Remove the caliper bracket by unscrewing the bolts.
- Slide off the rotor from the hub assembly.
- Install the new rotor, ensuring it is seated correctly.
- Reattach the caliper bracket and torque to specifications.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten lug nuts in a crisscross pattern to the specified torque (typically 100-150 ft-lbs).
