19A NCAC 03D .0532 BRAKES
No vehicle brakes shall be approved for an inspection sticker unless the items indicated in this Rule are inspected and found to meet the minimum requirements established in G.S. 20-124 and this Rule.
(1) Footbrakes shall not be approved if:
(a) When applying brakes to moving vehicle, braking force is not distributed evenly to all wheels originally equipped with brakes by the manufacturer. (The inspection mechanic must drive vehicle to make this test. The inspector may check the brakes while driving vehicle forward into the inspection area.)
(b) There is audible indication (metal on metal) that the brake lining is worn to the extent that it is no longer serviceable. (The wheel must be pulled and the brake lining examined when this occurs.)
(c) Pedal reserve is less than 1/3 of the total possible travel when the brakes are fully applied, or does not meet the manufacturer's specification for power brakes or air brakes.
(d) The reservoir of the master cylinder is not full. (Only brake fluid meeting SAE specifications for heavy duty hydraulic brake fluid shall be used when adding or changing brake fluid.)
(e) There is a visible leakage or audible seepage in hydraulic, vacuum or air lines and cylinders, or visible cracked, chafed, worn, or weakened hoses.
(f) The vehicle has any part of the brake system removed or disconnected.
(g) The brake pedal moves slowly toward the toeboard (indicating fluid leakage) while pedal pressure is maintained for one minute.
(2) Inspection mechanics are not expected to remove wheels in order to inspect the brakes. (Except as provided in Sub-item (1)(b) of this Rule.) Inspection mechanic must raise vehicle to get beneath to check underside.
(3) Handbrakes (auxiliary, parking or holding) shall not be approved if:
(a) There is no lever reserve when the brake is fully applied.
(b) Cables are visibly frayed or frozen, or there are missing or defective cotter pins or broken or missing retracting springs or worn rods or couplings.
(c) The operating mechanism, when fully applied, fails to hold the brakes in the applied position without manual effort.
(d) When emergency or handbrakes are applied they fail to hold vehicle.
