Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a socket set.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the pads. If they are less than 3mm, they should be replaced.
Replace Brake Pads:
- Remove the caliper bolts with a socket set.
- Slide the caliper off the rotor and secure it with a bungee cord to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for deep grooves or significant wear on the rotor surface.
Replace Rotors:
- If damaged, remove the rotor by unscrewing the retaining screws (if equipped) and gently tapping with a hammer if stuck.
- Install new rotors, aligning them with the wheel hub.
- Reinstall any retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specification (typically around 76 lb-ft).
Pump the brake pedal to ensure proper pressure before moving the vehicle.
