Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel covering the affected brake caliper.

3. Remove the Brake Caliper

Loosen and remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the brake rotor.
Support the caliper with a bungee cord or wire to avoid strain on the brake line.

4. Inspect and Clean

Inspect the caliper’s piston for damage or corrosion.
Clean the caliper and piston using brake cleaner.
Check the rubber seals for wear and replace if necessary.

5. Rebuild or Replace the Caliper

If the piston is damaged, consider rebuilding the caliper with a rebuild kit or replacing it with a new caliper.
To rebuild, remove the piston and replace seals, ensuring all components are lubricated correctly.

6. Reinstall the Caliper

Slide the caliper back onto the rotor.
Reinstall and torque the caliper mounting bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reconnect the brake line if it was removed.

7. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten the lug nuts in a crisscross pattern.
Lower the vehicle from the jack stands and remove the jack.

8. Final Check

Reconnect the battery and pump the brake pedal to ensure proper caliper function.
Check the brake fluid level and top off if necessary.
