Solution

1. Preparation

Gather tools and materials.
Safety gear: gloves and safety goggles.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts on the wheel.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Clean Calipers

Inspect calipers for any signs of damage or leaks.
Clean the caliper surface with brake cleaner to remove dirt and debris.
Check the caliper piston for corrosion or seizing; apply lubricant if necessary.

4. Replace Brake Pads (if necessary)

Remove the caliper by unbolting it from the bracket using a socket set.
Slide out the old brake pads from the caliper bracket.
Insert new brake pads, ensuring they are seated correctly.
Reinstall the caliper over the new pads and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (generally 80-100 ft-lbs).
Pump the brake pedal a few times to seat the pads against the rotors.
