Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly while the vehicle is on the ground.
Jack the vehicle up and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench.
Locate the caliper mounting bolts and remove them using the socket set.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or rope to avoid straining the brake line.

4. Inspect and Clean Caliper Components

Inspect the caliper for corrosion or damage.
Clean the caliper slide pins and mounting bracket with brake cleaner.
Apply a thin layer of high-temperature grease to the caliper slide pins.

5. Check Brake Pads and Rotors

Inspect brake pads for uneven wear; replace if necessary.
Check the brake rotor for warping or grooves; resurfacing or replacement may be needed.

6. Reassemble

Slide the caliper back onto the rotor and secure it with the mounting bolts. Torque to manufacturer specifications (typically around 25-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and securely tighten the lug nuts in a crisscross pattern to ensure even pressure.
