Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and secure.
Lift the vehicle using a jack and support with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for wear indicators; if they are worn down to the metal, replacement is necessary.
Remove Brake Pads:
- Remove caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new brake pads.
- Insert the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Inspect Rotors:
- Check for deep grooves or warping.
Remove Rotors:
- If worn, remove the caliper bracket and then the rotor.
Install New Rotors:
- Place new rotors on the hub and secure with bolts.
- Reattach the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads.
Tighten caliper bolts to manufacturer specifications.
Reinstall the wheel and lug nuts, tightening in a crisscross pattern.
Lower the vehicle and test brake function.
