A piston belonging to the pneumatic brake cylinders of your trailer is extended to its maximum during braking. What danger can this present?

When the piston in the pneumatic brake cylinder of your trailer is extended to its maximum during braking, it means the brake mechanism has reached the limit of its movement. This can reduce the actual braking force, because the system cannot press the brake pads or shoes any further against the drum or disc. As a result, the braking efficiency is reduced and the trailer may not slow down or stop as effectively as expected. This situation is dangerous, especially in emergency situations or on steep descents, because the trailer’s braking power is compromised. It is important to ensure your brake system is properly adjusted and maintained so that the piston does not reach its end position under normal braking loads.
