Solution

1. Preparation

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

2. Remove Wheel

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

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the rotor. If it is stuck, gently tap it with a rubber mallet.
Support the caliper with a bungee cord or rope to avoid stressing the brake line.

4. Inspect and Clean

Examine the caliper for signs of rust or damage. If the piston or caliper body is damaged, replacement may be necessary.
Clean the caliper and brake pads with brake cleaner to remove debris and contaminants.

5. Freeing the Caliper

If the caliper piston is stuck, use a caliper tool to compress and retract it slowly. Apply brake lubricant to the piston and cylinder to help it move freely.
Check the caliper slide pins for movement; remove and clean them if necessary, then reapply grease.

6. Reassemble Components

Reinstall the caliper over the rotor and secure it with the mounting bolts. Torque the bolts to the manufacturer’s specifications.
Reinstall the wheel and lug nuts, and lower the vehicle back to the ground.

7. Final Checks

Reconnect the battery and check the brake fluid level, topping off if necessary.
Pump the brake pedal to seat the caliper and pads.
