Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove the Wheel

Use the lug wrench to loosen the lug nuts slightly before raising the vehicle.
Jack up the vehicle and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect the Brake Caliper

Visually inspect the caliper for any signs of damage or corrosion.
Check the caliper pistons for proper movement; push them back gently to see if they return smoothly.
Look for brake fluid leaks around the caliper seals.

4. Replace the Brake Caliper (if necessary)

If the caliper is determined to be faulty:
- Use a socket set to remove the caliper mounting bolts.
- Carefully detach the brake line from the caliper, allowing brake fluid to drain into a container.
- Replace with a new or remanufactured caliper, ensuring the brake line is securely attached and the mounting bolts are torqued to the manufacturer's specifications.
- Bleed the brake system to remove any air from the lines.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified values.
Perform a test drive to ensure brakes function correctly.
