Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket set and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Remove the brake caliper by unbolting it from its mount. Slide the caliper off the rotor and hang it securely using a bungee cord.
Replace: If the brake pads are worn down (less than 1/8 inch), remove them from the caliper bracket. Install new brake pads, ensuring they are properly oriented.
Tools Required: Socket set, bungee cord, brake pad spreader tool.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Rotors: If rotors are scored or damaged, remove them by unbolting the caliper bracket and then the rotor.
Replace with New Rotors: Install new rotors, ensuring they are clean and free of grease or debris.
Tools Required: Socket set, torque wrench (for reinstallation), brake cleaner.

5. Reassemble Braking System

Reinstall the brake caliper and ensure it is securely mounted.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from jack stands and tighten the lug nuts to the manufacturer’s specified torque.
