Brake System Inspection
BRAKE SYSTEM INSPECTION
Inspect the complete system. Inspect brake lines and hoses for proper hook-up, binding, leaks, cracks and chafing. Inspect disc pads and drum linings for wear and disc rotors for surface condition. Inspect all other brake parts including drums, wheel cylinders and calipers. Inspect parking brake adjustment. You may need to have your brakes inspected more often if your driving habits or conditions result in frequent braking.
