Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Safety: Engage the parking brake and wear safety glasses.

2. Remove Wheel

Loosen the lug nuts while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect:
- Check the brake rotor surface for warping or scoring.
- Use a dial indicator to measure rotor runout; if it exceeds specifications, replace the rotors.
Replace:
- Remove the caliper by unbolting it from the bracket and hanging it safely (do not let it dangle by the brake line).
- Remove the brake pads from the caliper bracket.
- Unbolt the rotor from the hub if necessary, then install the new rotor.
- Reattach the caliper and install new brake pads.

4. Inspect and Replace Brake Pads

If the brake pads are worn beyond manufacturer specifications, replace them.
Ensure the caliper slides smoothly and lubricate if necessary.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
Test the brakes by pressing the pedal a few times to seat the pads against the rotors.
