Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen lug nuts on the wheel(s) where brake pads will be inspected or replaced.

2. Wheel Removal

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the braking system.

3. Brake Pad Inspection and Replacement

Inspect Brake Pads:
- Check each brake pad for uneven wear patterns and thickness.
Remove Old Brake Pads:
- Use a socket set to remove caliper bolts.
- Carefully slide the caliper off the rotor and support it without straining the brake line.
- Remove the old brake pads from the caliper bracket.
Replace Brake Pads:
- Install new brake pads in the caliper bracket.
- Apply brake grease on the backing of the pads to reduce noise.

4. Caliper Reinstallation

Reattach Caliper:
- Position the caliper back over the rotor and align it with the bracket.
- Tighten the caliper bolts to the manufacturer's specified torque (typically around 25-30 ft-lbs).

5. Brake System Check

Inspect Rotors:
- If rotors are warped, consider resurfacing or replacing them.
Reinstall Wheel:
- Place the wheel back on, hand-tighten lug nuts, and then lower the vehicle.
Torque Lug Nuts:
- Torque lug nuts to the manufacturer's specifications (usually around 75-85 ft-lbs).
