Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, brake cleaner, anti-seize lubricant, torque wrench.
Ensure vehicle is parked on a level surface and the engine is off.
Safety Warning: Disconnect the battery to avoid any electrical issues.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle (depending on the brakes being serviced).
Securely place jack stands under the vehicle for safety.

3. Remove Wheels

Use the lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to access the brake components.

4. Inspect Brake Components

Check the brake pads for thickness; replace if less than 3mm.
Inspect the brake rotors for any grooves or warping; consider resurfacing or replacing if necessary.
Clean the brake assembly using brake cleaner to remove dust and debris.

5. Lubricate Components

Apply anti-seize lubricant to the back of the brake pads and any contact points on the caliper.
Ensure that the caliper hardware and guide pins are also lubricated to prevent sticking.

6. Reassemble Brakes

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.

7. Final Checks

Tighten the lug nuts to the manufacturer's specified torque value (typically around 80-100 ft-lbs).
Reconnect the battery if it was disconnected.
