Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Wear safety gloves and eye protection.

2. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Carefully take off the wheel to expose the brake components.

3. Remove the Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; support it with a bungee cord or similar device.

4. Inspect and Service the Caliper

Check the caliper piston for smooth operation; clean and lubricate the piston with brake grease if necessary.
Inspect the caliper slides and brackets for corrosion or dirt; clean them with brake cleaner and a wire brush.
Apply high-temperature grease to the caliper slides to ensure they move freely.

5. Replace Components (if necessary)

If the caliper is damaged or the piston is seized, replace the caliper with a new or remanufactured unit.
Replace brake pads if they show uneven wear or are below the manufacturer’s recommended thickness.

6. Reassemble the Brake System

Slide the caliper back onto the rotor and secure it with the mounting bolts; torque to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and secure the lug nuts in a crisscross pattern to ensure even pressure.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification.
