You want to drive an agricultural tractor with two trailers equipped with compressed-air brakes. What do you have to ensure you do with the manual brake power regulator on each of the trailers?

When towing trailers with compressed-air brakes, German traffic rules require you to adjust the manual brake power regulator according to the load on each trailer. This means that the brake force applied should match the actual weight the trailer is carrying at the moment, not just the weight of the tractor or the trailer's maximum capacity. Proper adjustment ensures safe braking performance by preventing the brakes from being too strong (which could cause skidding) or too weak (which could reduce braking effectiveness). Therefore, always set the brake regulator to the current load on each trailer to maintain optimal control and safety.
