Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Loosen lug nuts using a socket set and remove the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check for wear indicators on the brake pads. If they are less than 3mm thick, replace them.
Remove Old Brake Pads: Unbolt the caliper using the appropriate socket and remove it. Slide the old pads out.
Install New Brake Pads: Apply brake grease to the pads' backing plates to reduce noise. Insert new pads into the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check Rotors: Measure rotor thickness with a micrometer. If below the minimum specification or if they are warped, they need replacement.
Remove Caliper Bracket: Take off the caliper bracket using the socket set.
Remove Rotors: If applicable, remove retaining screws and slide the rotor off the hub.
Install New Rotors: Position the new rotor onto the hub and secure it.

5. Reassemble Braking System

Reattach the caliper bracket and torque bolts to manufacturer specifications (typically 80-100 lb-ft).
Reinstall the caliper over the new pads and torque to specification.
Reattach the wheel and torque the lug nuts in a star pattern.
