DRAWING 5.3A REGULATION OF MAIN BRAKES

(1) expander arm, (2) expander shaft, (3) regulation screw

TABLE 5.1

MAIN BRAKE BRAKING FORCE

UNIT

124.5

Regulation should be conducted separately for each wheel. After proper brake regulation, at

full braking the axle shaft expander arm should create an angle of 90

with pneumatic ram

piston. With properly regulated brakes, trailer main brake braking force should reach a value

not less than that given in table(5.1).

ATTENTION!

Braking force of the trailer, is the braking force of all trailer wheels.

Difference in braking force may not be greater than 30%, considering that 100% constitutes

greater force.
