Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, C-clamp, brake cleaner, socket set, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands securely.

2. Remove the Wheel

Loosen the lug nuts on the wheel.
Use the jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Clean the Caliper

Use brake cleaner to clean the exterior of the caliper and surrounding area.
Check for rust or debris on the caliper and mounting bracket.
If necessary, remove the caliper by unscrewing the bolts holding it to the bracket.

4. Service the Caliper Slide Pins

Remove the slide pins from the caliper.
Clean the pins and the corresponding holes in the caliper with brake cleaner.
Apply a thin layer of high-temperature brake grease on the slide pins.
Reinstall the slide pins, ensuring they move freely.

5. Replace Brake Pads if Necessary

Inspect the brake pads for uneven wear; replace them if they are worn down.
Install new brake pads if needed, ensuring they are properly seated in the caliper bracket.

6. Reassemble and Test

Reattach the caliper to the bracket and torque the mounting bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern.
Lower the vehicle and tighten the lug nuts to the specified torque.
