Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during repair.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Use a jack to lift the vehicle securely and place jack stands underneath for safety.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper brackets for debris and clean if necessary.
Insert new brake pads into the caliper bracket. Ensure they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
Install new rotors, ensuring they are clean and free of grease.
Torque the retaining screws to the manufacturer’s specifications.

5. Reassemble and Recheck

Reinstall the brake caliper over the new brake pads, ensuring it fits securely.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the battery.
