AIRBRAKE SYSTEM - CONTINUED
REAR BRAKE ASSEMBLIES (Four)
Cam-actuated conventional brake assembly mounted to each axle. Applying brake pedal pushes brakeshoes against
brakedrums to slow down vehicle. Return springs pull brakeshoes away from brakedrums when brake pedal is released.
A slack adjuster mounted on each brake camshaft allows uniform adjustment of brakes.
FRONT BRAKE ASSEMBLIES (Two)
Double wedge-actuated conventional brake assembly mounted to front axle. Applying brakes forces a wedge between two
rollers and plungers, causing plungers to spread apart pushing brakeshoes against brakedrum.
