Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a hydraulic jack and support it with jack stands.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Locate the brake caliper and remove the caliper mounting bolts with the appropriate socket.
3. Carefully lift the caliper off the rotor; do not let it hang by the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Inspect the brake pads for wear; replace if they are below the minimum thickness (usually around 3mm).
6. Apply brake grease to the backing of the new brake pads to reduce noise.
7. Install the new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or warped, remove them by unscrewing the rotor retaining screws (if applicable).
2. Clean the hub surface with a wire brush to ensure proper rotor seating.
3. Install new rotors by aligning them with the wheel hub and securing with screws.

4. Reassemble Brake Caliper

Sub-steps:
1. Reposition the caliper over the new brake pads and rotor.
2. Tighten the caliper mounting bolts to the manufacturer's specified torque (usually around 25-35 ft-lbs).
3. Repeat the process for the opposite side if needed.

5. Final Checks

Sub-steps:
1. Lower the vehicle and remove wheel chocks.
2. Pump the brake pedal several times to ensure proper brake pad seating.
3. Check brake fluid level and top off if necessary.
