Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Disconnect the battery for safety.

2. Remove Wheel

Tools Required: Socket set, lug wrench.
- Loosen the lug nuts slightly while the wheel is still on the ground.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Tools Required: Visual inspection tools (flashlight).
- Inspect the brake pads for wear. Replace if the lining is less than 3mm thick.
- Check the brake rotor surface for grooves or uneven wear; measure thickness with a micrometer.
- If rotors are below minimum thickness or damaged, they should be resurfaced or replaced.

4. Replace Brake Pads and Rotors

Tools Required: Brake caliper tool, socket set, torque wrench.
- Remove the caliper bolts and slide the caliper off the rotor. Support the caliper with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- If replacing rotors, remove the rotor from the hub by unscrewing the retaining screws (if equipped).
- Install new rotors (if applicable) and torque the screws to manufacturer specifications (generally around 10-15 ft-lbs).
- Install new brake pads into the caliper bracket ensuring they are positioned correctly.

5. Reassemble

Tools Required: Torque wrench.
- Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and then use the torque wrench to tighten lug nuts to specifications (usually 80-100 ft-lbs).

6. Final Checks

Tools Required: Brake fluid (if needed), brake pedal.
- Check brake fluid levels in the reservoir and top off if necessary.
- Pump the brake pedal several times to seat the new pads against the rotor.
- Conduct a brief test drive at low speed to ensure the brakes are functioning correctly.
