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 lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the brake rotor.
- Check the pads for uneven wear; replace if necessary.
Replace Brake Pads:
- If replacement is needed, remove the old pads from the caliper bracket.
- Apply brake grease to the back of the new pads to prevent noise.
- Install the new pads into the caliper bracket.

4. Inspect and Clean Calipers

Check calipers for proper movement; clean and lubricate if necessary.
If calipers are stuck, consider rebuilding or replacing them.

5. Inspect Rotors

Check rotor thickness using a micrometer; replace if below the minimum specification.
Resurface rotors if they are within specifications but have scoring.

6. Reassemble and Test

Reinstall the caliper and torque bolts to manufacturer specifications (usually around 75-85 ft-lbs).
Reinstall the wheel and lower the vehicle.
Pump the brake pedal to seat the pads before driving.
