Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts with a tire iron 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 to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid stress on the brake line.
- Inspect the brake pads for wear; replace if the friction material is below 3mm.
Brake Rotors:
- Check for any scoring or grooves on the surface.
- Measure the thickness with a micrometer; replace if below manufacturer specifications.

4. Replace Components (if necessary)

Brake Pads:
- If replacement is necessary, remove the old pads and install new ones, ensuring they are seated properly.
Brake Rotors:
- If rotors are worn, remove them by unscrewing any retaining screws, then replace with new rotors.

5. Reassemble the Brake System

Slide the caliper back over the new pads and rotor.
Reinstall caliper bolts and torque to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to specification.
Pump the brake pedal a few times to ensure proper placement of pads.
