Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent movement.

2. Remove Wheel

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

3. Inspect Caliper

Sub-steps:
1. Visually inspect the caliper for signs of damage or leaks.
2. Check the brake line and fittings for any signs of wear or leaks.
3. Ensure the caliper slides freely without binding.

4. Replace Caliper (if needed)

Sub-steps:
1. Remove the caliper mounting bolts using a socket set.
2. Carefully slide the caliper off the brake rotor.
3. Disconnect the brake line from the caliper using a flare-nut wrench, ensuring a container is present to catch any fluid.
4. Install the new caliper by reversing the removal steps.
5. Fill the brake system with fresh brake fluid and bleed the brakes to remove air.

5. Reassemble

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
3. Test the brake pedal for firmness before driving.
