Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Wheel Removal

Using a lug wrench, loosen the lug nuts on the wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a dial indicator to measure rotor runout; if out of specification (usually more than 0.002 inches), consider replacement.
Remove Rotors:
- Remove the caliper by unbolting it from the bracket using a socket set.
- Support the caliper with a bungee cord or hang it to avoid stress on the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install New Rotors:
- Place the new rotor onto the hub.
- Reinstall any retaining screws if applicable.

4. Inspect and Replace Brake Pads

Remove Brake Pads:
- Remove the caliper bracket by unbolting it, then slide out the old brake pads.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to reduce noise.
- Slide the new brake pads into position within the caliper bracket.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and torque the bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 150-175 ft-lbs).
Reconnect the battery and check the brake fluid level; top off if necessary.
Pump the brake pedal until it feels firm.
