Solution

1. Preparation

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

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket wrench.
Carefully slide the caliper off the brake rotor, ensuring not to damage the brake line.
Support the caliper using a bungee cord or similar tool to prevent stress on the brake line.

4. Inspect and Clean

Inspect the caliper for corrosion or damage, particularly around the piston and mounting points.
Clean the caliper slides and piston area using brake cleaner and a wire brush.
Lubricate the caliper slide pins with high-temperature brake grease.

5. Replace or Repair Components

If the caliper is damaged, replace it with a new or remanufactured unit.
If the piston is sticking, consider rebuilding the caliper with a rebuild kit, including new seals and dust boots.

6. Reassemble

Slide the caliper back onto the rotor and reinstall the caliper mounting bolts, tightening them to the manufacturer's specifications (typically 20-25 lb-ft).
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.

7. Bleed the Brakes

If brake fluid was displaced, bleed the brake system to remove air bubbles.
Use a brake bleeder kit or have an assistant depress the brake pedal while you open and close the bleeder valve.
