Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Use wheel chocks to prevent movement.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts on the wheel before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the pads; if they are less than 3mm, they need replacement.
Remove Brake Caliper:
- Use a socket set to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads into the bracket ensuring that they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition: If the rotors are scored or below manufacturer specifications, they should be replaced.
Remove Rotors:
- If necessary, remove the caliper bracket by unscrewing the mounting bolts.
- Slide the rotor off the hub.
Install New Rotors: Align the new rotors onto the hub and secure them as per manufacturer specifications.

5. Reassemble Brake System

Reinstall Caliper:
- Position the caliper back over the new pads and rotor.
- Secure the caliper with the bolts and torque to manufacturer specifications.
Reattach Wheel:
- Place the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to the specified torque.

6. Final Checks

Check Brake Fluid Level: Ensure the fluid is at the correct level in the master cylinder.
Test Brake Function: Before driving, pump the brake pedal to ensure proper pad seating.
