Solution

1. Preparation

Gather tools: socket set, torque wrench, C-clamp, brake cleaner, and safety goggles.
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the wheels before lifting the vehicle.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, as necessary.
Secure the vehicle with jack stands.

3. Remove Wheel

Remove the loosened lug nuts completely and take off the wheel.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; pads should be at least 1/4 inch thick.
- Look for uneven wear or damage.
Replace Brake Pads:
- Remove caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord or wire.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are correctly seated.
- Compress the caliper piston using a C-clamp to allow room for the new pads.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for warping or scoring; replace if necessary.
Replace Rotors:
- Remove caliper bracket bolts and take the bracket off.
- Slide the rotor off the hub.
- Clean the hub surface and install the new rotor.
- Reinstall the caliper bracket and torque to manufacturer specifications.

6. Reassemble

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to specification.
Place the wheel back on and hand-tighten the lug nuts.

7. Lower Vehicle

Remove jack stands and lower the vehicle.
Torque the lug nuts to manufacturer specifications in a crisscross pattern.
