Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Remove Brake Components

Remove brake caliper:
- Use a socket set to remove caliper bolts.
- Suspend the caliper using a bungee cord or rope to avoid stress on the brake line.
Remove brake pads:
- Slide out the brake pads from the caliper bracket.

4. Inspect and Replace Parts

Inspect brake pads:
- Check for thickness; replace if less than 1/8 inch.
Inspect rotors:
- Measure rotor thickness with a micrometer; replace if below minimum specifications or if scored.
- If warped, resurface or replace rotors as necessary.
Replace components:
- Install new brake pads and ensure they are properly seated.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually between 20-30 ft-lbs).

5. Reassemble

Reinstall the wheels and torque lug nuts to specification (typically 80-100 ft-lbs).
Lower the vehicle back to the ground.

6. Final Checks

Pump the brake pedal to ensure proper contact between pads and rotors.
Check brake fluid level and top off if necessary.
