NOTE
While trying to remove nut from caging bolt, the caging bolt may become unseated
from brake chamber and pull out. If the caging bolt comes out, remove nut and
washer from caging bolt by hand.
i. If air pressure is available, release semitrailer brakes to compress spring brake. This will reduce effort required to
uncage brakes.
j. To uncage brakes, turn nut (1) counterclockwise and remove nut (1) and washer (2). This will release brakes
from caged position to full operating position/condition. Rotate caging bolt (3) counterclockwise and remove from
brake chamber (4).
