Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear gloves and safety goggles for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which caliper is sticking.
Secure the vehicle with jack stands.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Take off the wheel to access the brake components.

4. Remove the Brake Caliper

Loosen and remove the caliper mounting bolts using a socket wrench.
Carefully slide the caliper off the brake rotor. Do not allow the caliper to hang by the brake line; support it with a bungee cord or similar tool.

5. Inspect and Clean

Remove the caliper piston using a caliper tool if necessary.
Inspect the caliper piston and bore for corrosion or debris.
Clean the caliper using brake cleaner and a soft brush.

6. Lubricate and Reassemble

Apply brake grease to the caliper slide pins and piston.
Reinstall the piston and ensure it moves freely.
Reattach the caliper to the brake rotor and tighten the mounting bolts to the manufacturer’s specified torque.

7. Reinstall the Wheel

Place the wheel back onto the hub.
Tighten the lug nuts in a criss-cross pattern to ensure even pressure.

8. Lower the Vehicle

Carefully lower the vehicle back to the ground using the jack.
Remove jack stands.

9. Test the Brakes

Pump the brake pedal a few times to seat the caliper and ensure proper function.
