Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake pad gauge, torque wrench.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery if necessary.
Gather all tools and replacement parts.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor without disconnecting the brake line.
- Inspect brake pads for uneven wear and measure thickness.
Replace Brake Pads (if necessary):
- If pads are unevenly worn, remove them from the caliper bracket.
- Apply brake grease to the back of new pads and install them in the caliper bracket.
- Ensure that the wear indicators are positioned correctly.

4. Check and Replace Brake Rotors (if necessary)

Measure rotor thickness to ensure it meets specifications. Replace if below minimum thickness.
If warping or scoring is present, remove the caliper bracket and rotor.
Install new rotors, ensuring they are torqued to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure with bolts, torquing to specification.
Reinstall the wheel and lug nuts, tightening them in a star pattern.
Lower the vehicle and reconnect the battery if disconnected.
Pump the brake pedal to seat the pads before driving.
