Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

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

3. Remove Caliper

Locate and remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the brake rotor.
Suspend the caliper using a bungee cord or rope to avoid straining the brake line.

4. Inspect and Clean

Inspect the caliper piston for dust and debris.
Use brake cleaner to clean the caliper and surrounding area.
Check the rubber seals for wear or damage; replace if necessary.

5. Free Stuck Piston

If the piston is stuck, use a brake caliper tool or a C-clamp to slowly push it back into the caliper housing.
If necessary, apply brake lubricant to the piston and seals to facilitate movement.

6. Reassemble Components

Reinstall the caliper over the rotor and secure it with mounting bolts.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

7. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically around 76 ft-lbs).

Tools Required:
