Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and safely secured with jack stands.
Disconnect the battery to avoid any electrical issues during the procedure.

2. Remove Wheel Assembly

Use a lug wrench to loosen the lug nuts and remove the wheel.
Secure the wheel in a safe location to prevent damage.

3. Inspect Brake Components

Remove the brake caliper bolts with a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
Remove the brake pads and inspect for uneven wear. Document the thickness.

4. Check Brake Rotor

Measure the rotor thickness with a micrometer; compare it to manufacturer specifications.
If warped, replace the rotor. If scoring is present, consider resurfacing if within limits.

5. Caliper Inspection

Check the caliper slides and pins for lubrication and proper movement.
Clean and lubricate with high-temperature brake grease.
Replace the caliper if it shows signs of sticking.

6. Reassemble Components

Install new or resurfaced rotors, ensuring they are secured to manufacturer specifications (torque values typically around 80-100 ft-lbs).
Insert new brake pads, ensuring they are positioned correctly.
Reattach the caliper and secure it with bolts.

7. Final Steps

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Reconnect the battery and perform a brake fluid inspection.
