Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, wire brush, torque wrench.
Safely park the vehicle on a level surface.
Engage the parking brake and wear safety goggles and gloves.

2. Lift the Vehicle

Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to raise the vehicle and support it securely with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Components

Brake Caliper Removal:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord or hang it to prevent strain on the brake line.
Brake Pad Removal:
- Remove the old brake pads from the caliper bracket.
Brake Rotor Removal:
- If necessary, remove the rotor by unscrewing any retaining screws or tapping gently with a hammer to dislodge it.

4. Inspect and Clean

Inspect Brake Components:
- Check brake pads for uneven wear or damage. Replace if worn below the manufacturer’s specifications.
- Inspect rotors for grooves or warping. Resurfacing may be required if they are still within thickness specifications; otherwise, replace.
Clean Surfaces:
- Use brake cleaner and a wire brush to clean the caliper bracket, rotor surface, and any mounting points.

5. Install New Parts

Install New Brake Pads:
- Apply a thin layer of brake grease to the back of the new pads to prevent noise.
- Position the new pads into the caliper bracket.
Install New or Resurfaced Rotor:
- Place the rotor onto the hub and secure with retaining screws if applicable.
Reattach Brake Caliper:
- Slide the caliper back over the new pads and rotor.
- Tighten caliper bolts to the manufacturer’s torque specifications.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
Pump the brake pedal several times to seat the brake pads.
