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 the moving
vehicle, the braking force is not distributed evenly to all wheels originally
equipped with brakes by the manufacturer. The inspection mechanic must drive
the 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 one third 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, the brake lines and hoses do not meet the
manufacturer's specifications, or are made of a material not approved for motor
vehicles; or
(g) once applied, and
while holding pedal pressure for one minute, the brake pedal gradually moves
toward the toeboard, indicating fluid leakage.
(2) Except as provided in Sub-item (1)(b) of
this Rule, inspection mechanics are not required to remove the wheels of a
vehicle to examine the condition of the brakes. An inspection mechanic shall
raise vehicles to check the underside of a vehicle, including the applicable
brake components list in this Rule.
(3) Auxiliary, parking, or holding handbrakes
shall not be approved if:
(a) there is no
lever reserve when the brake is fully applied;
(b) cables are visibly frayed or frozen;
there are missing or defective cotter pins; there are broken or missing
retracting springs; or there are worn rods or couplings;
(c) the operating mechanism, when fully
applied, fails to hold the brakes in the applied position without manual
effort; and
