Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket set and take off the wheel to access the caliper.

3. Inspect and Clean Caliper

Inspect the caliper for leaks, cracks, or wear.
Clean the caliper surface using brake cleaner to remove any debris and dirt.

4. Replace Caliper (if necessary)

If the caliper is leaking or damaged:
1. Disconnect the brake line using a flare nut wrench, and allow any brake fluid to drain safely into a container.
2. Remove the caliper mounting bolts with a socket set.
3. Remove the caliper from the rotor and inspect the brake pads.
4. Install the new caliper in reverse order of removal, ensuring to use new copper washers on the brake line connection.
5. Torque the caliper mounting bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

5. Reinstall Wheel and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer’s specifications (typically around 100-120 ft-lbs).
Reconnect the battery and pump the brake pedal a few times to seat the new caliper.
