Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, brake cleaner, torque wrench, socket set, flathead screwdriver, caliper tool, rubber mallet.
Safety Warnings: Ensure the vehicle is on a level surface and secure with wheel chocks. Disconnect the battery before starting work on electrical components.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Elevate the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

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

4. Inspect and Clean Caliper Components

Remove the caliper bracket if necessary to access the slider pins.
Inspect the slider pins for corrosion or damage. Clean them with brake cleaner and a cloth.
Apply a thin layer of brake grease to the slider pins and reinsert them.

5. Replace or Rebuild Caliper if Necessary

If the caliper is damaged or the piston is sticking, consider rebuilding or replacing the caliper.
For a rebuild, remove the piston using a caliper tool. Clean and inspect the piston and seals.
Replace any damaged components with new parts.

6. Reassemble Components

Reattach the caliper to the bracket and tighten the mounting bolts to the manufacturer's torque specifications (usually around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Finalize

Lower the vehicle to the ground and remove the jack stands.
Tighten the lug nuts to the manufacturer's torque specifications (usually around 120-140 Nm).
Reconnect the battery if it was disconnected.
