Solution

1. Preparation

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

2. Lift and Remove Wheel

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

3. Remove the Brake Caliper

Locate the caliper mounting bolts (usually two bolts).
Use a socket wrench to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor without stretching the brake line. Support the caliper with a bungee cord or rope to avoid hanging it by the brake line.

4. Inspect and Clean the Caliper

Check the caliper piston for signs of rust or corrosion.
Use brake cleaner and a brush to remove debris and dirt around the caliper and piston.
Inspect the caliper slides; if they are sticky or corroded, they should be cleaned and lubricated with high-temperature brake grease.

5. Replace or Rebuild the Caliper

If the caliper is damaged, replace it with a new or rebuilt unit.
If rebuilding, replace the caliper seals and piston as necessary.

6. Reinstall the Caliper

Slide the caliper back over the rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer’s specifications (typically 20-30 lb-ft).
Reattach the wheel and torque the lug nuts to the manufacturer’s specifications (usually 76-80 lb-ft).

7. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper caliper operation.
Check the brake fluid level and add fluid if necessary.
