Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gloves and goggles.

2. Lift Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the brake caliper bolts using a socket set.
- Carefully lift the caliper and support it without stressing the brake line.
- Remove the brake pads from the caliper bracket.
Replace Brake Pads (if worn):
- Compare new brake pads to old ones to ensure correct fit.
- Install new pads into the caliper bracket and apply brake grease on the back of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check rotors for scoring or damage. If they are worn beyond the manufacturer's specifications, they must be replaced.
Replace Rotors (if required):
- Remove the rotor from the hub by removing any retaining screws or caliper bracket.
- Install the new rotor and torque to manufacturer's specifications.

5. Reassemble Braking System

Reinstall the brake caliper over the new pads and torque caliper bolts to specifications.
Reinstall the wheel and lower the vehicle.
Torque wheel nuts to the manufacturer’s recommended specification.
