Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Remove the wheel:
- Use a lug wrench to loosen and remove the wheel nuts.
- Lift the vehicle with a jack and secure it with jack stands.
Remove the brake caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Check brake pads:
- Inspect the brake pads for thickness; replace if they are below 3mm.
- If the pads are worn out, proceed to replace them.
Install new brake pads:
- Clean the caliper bracket and apply brake grease to the backing of the new pads.
- Slide the new pads into place.

3. Inspect and Replace Brake Rotors

Check rotor condition:
- Use a micrometer to measure rotor thickness; it should meet manufacturer specifications.
- If warped or below specifications, remove the rotors.
Remove the rotor:
- If necessary, remove the rotor retaining screws or clips and pull the rotor off the hub.
Install new rotors:
- Clean the hub surface and install new rotors, securing them with screws or clips.

4. Reassemble and Test

Reattach the caliper:
- Position the caliper over the new pads and rotor.
- Tighten the caliper mounting bolts to the manufacturer’s torque specifications.
Reinstall the wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value.
