Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Pads

Remove the Wheel:
- Use a jack to raise the vehicle and secure with jack stands.
- Remove the lug nuts using a socket set and take off the wheel.
Inspect Brake Pads:
- Check the thickness of the brake pads; replace if worn below manufacturer's specification.
- If necessary, remove the caliper bolts and slide the caliper off the rotor.
- Remove the old brake pads.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to reduce noise.
- Insert the new brake pads into the caliper bracket.
- Reattach the caliper over the new pads and tighten the bolts to the specified torque (usually around 25-30 ft-lbs).

3. Inspect and Replace Brake Rotors

Check Rotor Condition:
- Measure rotor thickness with a micrometer; replace if below minimum thickness.
- Look for signs of warping or uneven wear.
Remove Rotors:
- If rotors are to be replaced, remove the caliper as described above.
- Unscrew the rotor retaining screws (if applicable) and slide the rotor off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Position the new rotor onto the hub and secure with retaining screws.
- Reinstall the caliper over the new rotor.

4. Reassemble and Test

Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
Reconnect the battery and perform a brake test before driving.
