Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake caliper tool, torque wrench, OBD-II scanner, brake cleaner.
Ensure the vehicle is parked on a flat surface and is in park (automatic) or neutral (manual).
Disconnect the battery to ensure safety during repairs.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which caliper is being serviced.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Wheel

Use a lug wrench to remove the wheel nuts.
Take off the wheel to access the brake caliper.

4. Inspect the Brake Caliper

Visually inspect the brake caliper for any signs of fluid leaks or physical damage.
Check the condition of the caliper piston; it should move freely without sticking.

5. Replace or Repair the Caliper

If replacing:
1. Remove the caliper mounting bolts using a socket wrench.
2. Detach the brake line from the caliper, allowing any remaining fluid to drain into a container.
3. Install the new caliper, ensuring to use new copper washers on the brake line connection.
4. Tighten the caliper mounting bolts to manufacturer specifications (typically around 25-30 ft-lbs).
If repairing:
1. Clean the caliper and piston thoroughly using brake cleaner.
2. Replace any damaged seals and reassemble the caliper.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 75-85 ft-lbs).
Reconnect the battery and test the brake pedal for firmness.
