Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a lug wrench to loosen wheel nuts before lifting the vehicle.
Lift the vehicle with a jack and support it with jack stands.
Completely remove the wheel to expose the brake assembly.

3. Inspect Brake Pads and Rotors

Measure the thickness of each brake pad using a caliper; replace any that are below manufacturer specifications (usually below 3mm).
Examine the brake rotor surface for grooves or uneven wear; replace if necessary.

4. Replace Worn Components

If brake pads need replacement, remove the caliper bolts using a socket set.
Slide the caliper off the bracket and hang it using a bungee cord (do not let it dangle by the brake line).
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.
Reinstall the caliper over the new brake pads, securing it with bolts to manufacturer torque specifications (usually around 25-30 ft-lbs).

5. Final Assembly

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
Reconnect the negative battery terminal.
