Procedures for Inspecting
Certain Commercial Motor Vehicles and Trailers Pursuant to Federal
Regulation. 49 CFR Parts 390 through 397, including Appendix G to
Sub-chapter B, as appearing or as may be revised in the Code of Federal
Regulations, as related to the inspection of Commercial Motor Vehicles or any
activity related thereto, are hereby adopted as the Regulations of the Registry
of Motor Vehicles. Said regulations are applicable to trucks with a gross
vehicle weight rating of over 10,000 lbs., buses transporting more than 15
passengers including the driver or any motor vehicle transporting hazardous
materials in a quantity requiring placarding in accordance with the Hazardous
Material Regulations of the United States Department of Transportation, 49 CFR
Parts 171 through 180. In the event of any conflict between
540 CMR 4.00 and any other
regulations or law of the Commonwealth of Massachusetts, the stricter more
stringent standard shall apply. A Certificate of Rejection shall be issued to
any vehicle or trailer submitted for inspection if any of the following
conditions exist:
(a)
Air Brake
Systems.
1.
Leakage
Test. Start the vehicle engine and run at fast idle until air
pressure on gauge reaches cut-off point. Cut-off must occur at 90 lbs. per
square inch (PSI) or more, or manufacturer specifications. Stop engine and
observe pressure gauge. With service brakes in released position, if drop in
pressure exceeds 2 PSI in one minute for a single vehicle or 3 PSI for a
combination vehicle or if audible leakage is evident, the vehicle will be
rejected. Start engine and allow system to reach maximum pressure. Stop engine
and apply service brakes, at which time a pressure drop of 5 PSI to 15 PSI will
occur and system will be stabilized. With brakes in applied position, if drop
in pressure exceeds 3 PSI in one minute for a single vehicle, or 4 PSI per
minute for a combination vehicle, or of audible leakage is evident, the vehicle
will be rejected.
2.
Low Pressure Warning Device Test. Apply service brakes
repeatedly until the audible and visual low pressure indicator comes on. Reject
vehicle if indicator comes on above 70 PSI or below 50 PSI or if the indicator
is inoperable. A gauge indicating pressure is not deemed to be an adequate low
pressure indicator.
3.
Condition of Air Brake Components. During the
inspection of the vehicle, the conditions of visible air brake components
should be checked. The vehicle shall be rejected if tubing or hoses are
cracked, chafed, or restricted or are insecurely fastened or improperly
retained.
(b)
Brake System.
1.
Service Brakes.
a.
All brake systems are to be inspected in accordance with the manufacturer(s)
recommended procedures. Absence of braking action of any axle required to have
brakes upon application of the service brakes (such as missing brakes or brake
shoe(s) failing to move upon application of a wedge, S-cam, cam, or disc
brake).
b. Missing or broken
mechanical components including shoes, lining, pads, springs, anchor pins,
spiders, cam rollers, push rods, and air chamber mounting bolts.
c. Loose brake components including air
chamber spiders, and cam shaft support brackets.
d. Audible air leak at brake chamber
(example-ruptured diaphragm, loose chamber clamp,
etc.).
e.
Readjustment Limits. The maximum stroke at which
brakes should be readjusted is given below. Any brake 1/4 inch or more
past the readjustment limit or any two brakes at the readjustment limit or less
than 1/4 inch beyond the readjustment limit shall be cause for rejection.
Stroke shall be measured with the engine off and reservoir pressure of 80 to 90
PSI with brakes fully applied.
