Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the negative terminal of the battery for safety.

2. Wheel Removal

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Brake Pad Inspection and Replacement

Inspect the brake pads for wear; if worn down to below 3mm, replace them.
If replacement is needed:
1. Remove the caliper bolts using a socket wrench.
2. Slide the caliper off the rotor. Support it with a bungee cord or hang it to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Apply brake grease to the back of the new brake pads to minimize noise.
5. Install the new brake pads into the caliper bracket.

4. Rotor Inspection and Replacement

Check the rotor surface for grooves or warping.
If replacement is necessary:
1. Remove the caliper bracket by unscrewing its mounting bolts.
2. Slide off the old rotor.
3. Clean the hub surface and install the new rotor.
4. Reattach the caliper bracket securely.

5. Reassembly

Reinstall the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.
