Solution

1. Preparation

Gather necessary tools and replacement parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout; if over specifications, replacement is necessary.
- Visually inspect for grooves or scoring.
Replacement:
- Remove caliper bolts and slide the caliper off the rotor (support caliper to avoid strain on brake line).
- Remove the rotor by unscrewing any retaining screws if present.
- Clean the hub surface and install the new rotor, ensuring it is seated properly.

4. Inspect and Replace Brake Pads

Remove the brake pads from the caliper bracket.
Check for uneven wear and replace if necessary.
If replacing, lubricate the backing of the new pads with anti-squeal lubricant and install them.

5. Reassemble Components

Reinstall the caliper over the new rotor and pads.
Torque caliper bolts to manufacturer specifications (typically around 20-30 lb-ft).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brake System

Lower the vehicle from jack stands.
Tighten the lug nuts in a star pattern to the specified torque (usually around 80-100 lb-ft).
Pump the brake pedal to ensure pads are seated properly before test driving.
