Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and secure with wheel chocks.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the vehicle from the designated lift points.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect the Brake Caliper

Visually inspect the caliper for rust, leaks, or physical damage.
Check the caliper piston movement by pressing the brake pedal lightly.

5. Freeing the Stuck Caliper (if applicable)

If caliper is stuck, apply brake cleaner to the caliper slides and bushings.
Use a rubber mallet to gently tap the caliper to help free it.
If still stuck, remove the caliper from the bracket using the appropriate socket.

6. Replace Caliper (if necessary)

Use a bench vise to compress the piston back into the caliper.
Install a new caliper and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).
Reattach brake lines and ensure there are no leaks.

7. Reassemble the Brake Assembly

Reinstall the wheel and lug nuts, tightening to the manufacturer's torque specification (usually around 76 ft-lbs).
Lower the vehicle back to the ground.
