Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, C-clamp, brake cleaner, socket set, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Remove Caliper

Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor.
Support the caliper using a bungee cord or a suitable hook to avoid stress on the brake line.

3. Inspect and Clean

Inspect the caliper for rust or damage.
Clean the caliper using brake cleaner.
Check the guide pins and bushings for wear; these should be free of corrosion and grease.

4. Address Sticking Piston

Use a C-clamp to gently push the piston back into the caliper. If it does not move smoothly, replace the caliper.
Lubricate the guide pins with high-temperature brake grease.

5. Reassemble Components

Reinstall the caliper over the rotor and secure it with the mounting bolts to the specified torque (consult the vehicle's service manual for the exact torque value).
Reinstall the wheel and lower the vehicle.

6. Final Checks

Pump the brake pedal a few times to seat the caliper and brake pads properly.
Inspect the brake fluid level and top up if necessary.
