Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, brake cleaner, socket set, torque wrench, and replacement parts if necessary.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Wheel

Use the lug wrench to loosen the lug nuts on the wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Remove Caliper

Locate the caliper bolts and use the socket set to remove them.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or similar device to avoid straining the brake line.
Inspect the caliper for any signs of damage or fluid leaks.

4. Inspect and Clean

Clean the caliper and surrounding area with brake cleaner to remove any dirt or debris.
Check the caliper piston for any signs of corrosion or damage.
If the caliper is stuck, consider rebuilding or replacing it.

5. Replace Caliper (if necessary)

If the caliper is found to be faulty, install the new caliper by reversing the removal steps.
Ensure that all connections are secure and that the caliper moves freely.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery and pump the brake pedal a few times to seat the caliper.
Test drive the vehicle to ensure proper braking performance.
