Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Put on safety glasses and gloves.
Gather necessary tools: jack, jack stands, lug wrench, and torque wrench.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to expose the brake caliper.

3. Inspect Calipers and Brake Pads

Visually inspect the caliper body for any signs of rust, corrosion, or fluid leaks.
Check the brake pads for thickness; replace if they are worn down to 3mm or less.
Ensure the caliper piston is not leaking brake fluid. If it is, the caliper may need to be rebuilt or replaced.

4. Test Caliper Movement

With the brake pedal pressed, observe the caliper movement. It should extend evenly and retract smoothly. If it sticks, clean or replace the caliper.
Inspect the caliper slide pins for lubrication and free movement. If they are stuck, clean and lubricate with brake grease.

5. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs for most vehicles).
