Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a jack to raise the front or rear of the vehicle, depending on which brakes are suspected to be faulty.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel bolts.
Carefully take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; they should be at least 1/8 inch thick.
- Look for signs of glazing or burning.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove the worn brake pads from the caliper bracket.
- Install new brake pads, ensuring they are correctly aligned.
- Reattach the caliper over the new pads and torque caliper bolts to manufacturer specifications.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for warping or excessive scoring.
Replace Rotors:
- Remove the caliper bracket if necessary to access the rotor.
- Remove the rotor from the hub.
- Install new rotors and ensure they are seated properly.
- Reattach the caliper bracket and torque bolts to specifications.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts in a crisscross pattern to specifications.

7. Test the Brake System

Refill brake fluid if necessary.
Pump the brake pedal to ensure proper feel before driving.
Test drive the vehicle to ensure the issue is resolved.
