Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Lift the Vehicle

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Check the surface of the rotor for grooves or scoring; replace if damaged.
- Measure rotor thickness with a micrometer; ensure it meets specifications.
Brake Calipers:
- Check for proper movement; ensure caliper slides are lubricated and not seized.

4. Replace Components (if necessary)

Replacing Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads, ensuring they fit snugly.
Replacing Brake Rotors:
- Remove the old rotor (may require a hammer to knock loose).
- Install the new rotor and secure with any retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
Reattach the wheel and lower the vehicle.
Pump the brake pedal several times to ensure proper pad seating.
