Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather safety equipment (gloves, goggles).

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Clean Brake Components

Caliper Inspection:
- Remove the caliper bolts using a socket set (check manufacturer specs for torque).
- Lift the caliper away from the rotor and inspect the caliper slides for corrosion or dirt.
- Clean the caliper slides with brake cleaner and a wire brush.
Brake Pad Inspection:
- Check the condition of the brake pads; replace if they are worn down below the minimum thickness.
- Ensure the pads are aligned correctly in the caliper bracket.

4. Address the Sticking Issue

Caliper Service:
- If the caliper slides are corroded, apply brake grease to the slides to ensure smooth operation.
- If the caliper piston is sticking, remove the piston using a caliper tool and clean/replace as necessary.
Parking Brake Adjustment:
- If applicable, adjust the parking brake mechanism as per the manufacturer’s specifications to ensure it is not overly tight.

5. Reassemble and Test

Reattach the caliper and secure it with bolts, tightening to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque.
Test the brake pedal for proper feel before taking the vehicle out for a test drive.
