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. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for wear; replace if the friction material is below 3 mm.
Brake Rotors:
- Check the surface of the rotors for grooves or rust.
- If damaged, replace the rotor. If only minor scoring is present, consider resurfacing.
Brake Calipers:
- Ensure the caliper is not sticking. Check the piston for free movement.
- If the caliper is seized, replace it.

4. Replace Components

If brake pads are worn, replace them:
- Apply brake grease to the backing of new pads.
- Install new pads into the caliper.
If rotors are replaced:
- Install the new rotor.
- Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 lb-ft).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 80-100 lb-ft).
Pump the brake pedal several times to ensure proper seating of the brake pads.
