Many of you ask us this question during your dealer visit. Today we want to tell you more about how trailer brakes work .
The braking system, which is mandatory equipment for a trailer with a GVW (permissible total laden weight) of more than 750 kg , guarantees excellent coupling security when braking the towing vehicle.
It should be noted that this braking device is also mandatory on a trailer if the trailer's unladen weight (PV) is at least half the weight of the towing vehicle .
ROAD BRAKE PRINCIPLE
When the towing vehicle brakes or slows down, the towing vehicle pushes the rear of the towing vehicle, which creates a horizontal force in the inertial brake control via the slide shaft.
This thrust is transmitted to the lever and thus to the rod, the cables and the control lever inside the brake, the emitter. Second, it pushes the jaws on the drums, causing it to brake .
GOING BACK
While the towing vehicle is reversing, it activates the control arm, brake control, rod, cables and spacer by pressing on the sliding shaft of the inertia brake control, pushing the jaws into contact with the drums.
However, unlike normal braking, the drums rotate in the opposite direction and engage and drive the detachable brake shoe. This detachable jaw makes it possible to eliminate braking during the total travel of the inertial braking control after tilting the automatic reverse lever. Remaining braking is negligible and can return to hitch.
HANDBRAKE
The handbrake is provided according to the following principle : Thanks to a compensator box mounted on the handbrake control brake lever and mounted on the tie rod, it is sufficient to pull the handbrake lever backwards to the last tooth to immobilize the trailer. shelf.
For long-term parking you will need to use wheel chocks. This will allow you to prevent the wheels from locking up (jaws sticking to the drums), especially in winter.
