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

In a pneumatic braking system for trailers, if the piston in the brake cylinder extends to its maximum, it means the brake pads are too far from the brake drum or disc. This causes reduced braking force because the brakes can't apply enough pressure, leading to less effective braking of the trailer. Proper adjustment is necessary to ensure the piston moves only a short distance during braking for optimal braking power. So, an overextended piston directly reduces the trailer's braking performance.
