Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure it on jack stands to ensure safety while working underneath.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Inspect the brake assembly for access to the caliper.

4. Inspect and Clean the Caliper

Visually inspect the caliper for any signs of sticking or damage.
If sticking is suspected, use a brake cleaner to spray and clean the caliper.
Check the caliper slider pins for proper lubrication and movement.

5. Test Caliper Movement

Remove the caliper from the bracket (if necessary) by unscrewing the bolts.
Manually move the caliper piston in and out using a C-clamp.
If the piston does not move freely, it may need to be replaced.

6. Reassemble Components

Reinstall the caliper, ensuring that the slider pins are lubricated and moving freely.
Replace the wheel and tighten the lug nuts to the manufacturer’s specified torque settings.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle to the ground.
