26502
. (a) Airbrakes of every motor vehicle and combination of
vehicles shall be so adjusted and maintained as to be capable of
providing full service brake application at all times except as
provided in subdivision (b) of Section 26311. A full service brake
application shall deliver to all brake chambers not less than 90
percent of the air reservoir pressure remaining with the brakes
applied.
(b) The department may by regulation authorize the use of special
devices or systems to automatically reduce the maximum air pressure
delivered to the brake chambers in order to compensate for load
variation and to obtain balanced braking. Permitted systems shall be
of the fail safe type and shall not increase the vehicle stopping
distance.
