Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Brake cleaner
- Torque wrench
- C-clamp (for caliper compression)
- Safety glasses and gloves
Safety Warnings:
- Always work on a flat, stable surface.
- Ensure the vehicle is securely supported on jack stands.

2. Remove Wheel

Loosen lug nuts slightly before lifting the vehicle.
Use the jack to elevate the vehicle and secure with jack stands.
Remove the lug nuts and then the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor.
- Check the thickness of the brake pads; replace if below the minimum thickness (usually 3mm).
Replace Brake Pads:
- If replacement is needed, compress the caliper piston using a C-clamp.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any visible scoring or damage on the rotor surface.
Replace Rotors:
- If replacement is necessary, remove the caliper bracket by unscrewing the mounting bolts.
- Slide the old rotor off the hub and install the new rotor.
- Reattach the caliper bracket and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten lug nuts to the specified torque in a star pattern.
Pump the brake pedal several times to ensure proper engagement of the brake pads.
