Solution

1. Preparation

Gather all necessary tools and parts.
Make sure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the pads; replace if less than 3mm.
Remove Old Brake Pads:
- Unbolt the caliper using a socket set.
- Slide the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
Install New Brake Pads:
- Apply brake grease to the backing of the new brake pads.
- Slide the new pads into place in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged (scored or warped), remove them by unbolting from the hub.
Clean the hub surface before installing new rotors.
Install new rotors by aligning them with bolt holes and tightening to manufacturer's torque specifications (typically 80-100 ft-lbs).

5. Reassemble Components

Reattach the caliper over the new brake pads.
Torque caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern to ensure even pressure.

6. Final Checks

Lower the vehicle and remove jack stands.
Pump the brake pedal several times to ensure proper seating of the brake pads.
Check brake fluid level and add if necessary.
