In short, you must be specific as to the truck''s job application.The truck and the trailer builder design the braking system based on axle loading. Overloaded vehicles will not comply with government standards, nor will they be in proper balance. To ensure the brake lining is not overrated for the loads that the axles will carry, you should specify a specific gross axle weight rating (GAWR) for their axles.Secondly, you must ensure that the brakes on the powered vehicle are compatible with the brakes on the trailer. This applies to foundation brakes and friction materials, to air transmission times and to proper piping and valves. Trends in air brake systems
