7.3 Manual Brake on the Trailer
Some trailers are fitted with a manual handbrake for additional safety. It operates
exactly like the mast brake. When the brake is pulled, it pulls a cable which is equally
distributed on both sides and that locks the wheels in place.
•
To engage the brake, pull handle until brake locks in a horizontal position,
parallel frame.
•
To disengage the sign brake, reverse the movement.
•
To adjust the tension on the cable, adjust knob at the end of the brake handle;
you must first loosen the screw that is perpendicular to the knob.
•
If the brakes are still too loose, you can adjust the cable by loosening the clamp
on the right-side wheel and moving the cable to get it tighter.

7.4 No Independent Trailer Braking System
If the trailer has no independent braking system, the trailer relies exclusively on the
application of the brakes on the tow vehicle to apply braking force to the trailer.
For safe and effective braking operations, it is
crucial
that the weight of the trailer does
not exceed the gross vehicle weight rating (GVWR) of the tow vehicle.
The tow vehicle GVWR is generally found on a label inside the door frame of the
vehicle.
The trailer GWR is on the trailer name plate at the front of the trailer.
