Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repairs.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which caliper is sticking.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the brake caliper.

4. Inspect the Brake Caliper

Visually inspect the caliper for signs of damage or rust.
Check the caliper slide pins; they should move freely.

5. Clean and Lubricate

Remove the caliper from the bracket by unscrewing the bolts.
Clean the caliper slide pins using brake cleaner and a wire brush.
Apply high-temperature brake grease to the slide pins and reinsert them.

6. Replace Brake Pads (if necessary)

If pads are unevenly worn, replace them with new pads.
Follow the manufacturer’s specifications for pad installation.

7. Reinstall the Caliper

Reattach the caliper to the bracket and torque the bolts to the manufacturer’s specifications (usually around 25-30 Nm).
Reinstall the wheel and torque the lug nuts to the specified value (typically 100-120 Nm).

8. Test the Brakes

Lower the vehicle and reconnect the battery.
Pump the brake pedal to seat the caliper and pads.
Test drive the vehicle at low speed to ensure proper braking function.
