foundation brake System (cont.)
WaRNING:
Never attempt to disassemble or repair a spring
brake chamber. Serious personal injury could
result from accidental sudden release of the
high-energy spring.
The slack adjuster functions as a lever in the brake
system. It converts the linear force of the brake
chamber into torque, which forces the brake shoes
against the drums. Trailers are built with automatic
slack adjusters. Automatic adjusters ensure
constant brake shoe force by maintaining brake
shoe to drum clearance.
WaRNING:
Service brakes and parking brakes must
be inspected by the driver before and after
operation. NeVeR operate a trailer with
defective brakes.
• Verify the brake chamber plastic end cap is in
place to seal out dirt and contaminants.
• Visually inspect all components for broken or
missing parts, damage, and corrosion.
• Ensure the service brake chamber clamping ring
is secure and damage-free.
• If a defect is suspected, place the vehicle out of
service until a qualified mechanic can perform
repairs.
WaRNING:
before entering traffic, check the operation of
the trailer brakes to ensure they are in proper
working order. operate the foot pedal, dash
control valves, and hand valve to verify the
brakes apply and release each time. listen and
be alert for air leaks during each type of brake
application.
