Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check thickness; replace if below manufacturer specifications.
Inspect Rotors:
- Measure rotor thickness; replace if below minimum specification or if warped.
- If rotors are salvageable, consider having them resurfaced.
Replace Brake Pads:
- Remove caliper bolts using the appropriate socket size.
- Slide off the caliper and support it with a bungee cord to avoid strain on the brake line.
- Replace old pads with new ones, ensuring proper orientation.
Replace Rotors (if needed):
- Remove rotor retaining screws (if applicable).
- Slide off old rotor and install new rotor, securing with screws.

4. Reassemble

Reattach the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer's specified torque.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and tighten lug nuts to the proper torque specifications.

5. Test Brakes

Pump the brake pedal to seat the new pads.
Check for any abnormal noises or issues while performing a test drive.
