Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, mechanic's gloves.
Safety Warnings: Ensure the vehicle is on a flat surface, and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Inspect Brake Components

Remove the brake caliper by unbolting the caliper bracket bolts.
Slide the caliper off the rotor and support it with a bungee cord or rope (do not let it hang on the brake line).
Remove the brake pads from the caliper bracket.

4. Examine Brake Pads and Rotors

Inspect the brake pads for uneven wear; replace any that are excessively worn.
Measure the thickness of the brake rotors; replace if below the minimum thickness specification (usually stamped on the rotor).
Clean the rotor surfaces with brake cleaner to remove any debris or contaminants.

5. Caliper and Hardware Inspection

Check caliper slides and pins for rust or debris; lubricate with brake grease if necessary.
Ensure that the caliper is not sticking; replace if faulty.

6. Reassemble and Torque

Reinstall the new or cleaned brake pads into the caliper bracket.
Reattach the caliper and ensure it is secured with the appropriate torque specification (usually around 20-30 ft-lbs, check manufacturer’s specs).
Reinstall the wheel and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
