Solution

1. Preparation

Gather tools and safety gear (gloves, safety glasses).
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Caliper

Sub-steps:
1. Visually inspect the brake caliper for any physical damage or leaks.
2. Check the condition of the caliper piston for rust or corrosion.
3. Ensure the caliper slides smoothly on its mounting points.

4. Replace or Repair Caliper

Sub-steps:
1. If replacement is necessary, remove the caliper mounting bolts using a socket set.
2. Carefully detach the caliper from the brake rotor and hang it with a bungee cord (do not let it dangle by the brake line).
3. Disconnect the brake line from the caliper using a line wrench to prevent damage.
4. Install the new or rebuilt caliper by reversing the removal steps, ensuring to torque the bolts to the manufacturer's specifications (typically around 25-30 lb-ft).
5. Reconnect the brake line and ensure all connections are secure.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle to the ground and fully tighten the lug nuts in a criss-cross pattern to the specified torque (usually 80-100 lb-ft).
3. Pump the brake pedal several times to ensure proper caliper function and to restore brake pressure.
4. Test drive the vehicle to ensure that the issue has been resolved.
