Abstract
When a vehicle decelerates quickly or otherwise experiences a hard brake event, the described systems and methods facilitate reducing load transfer between axles of a common set of axles (e.g. a tandem axle, a tridem axle, etc.). Transfer of suspension pressure from a dynamically unloaded axle to a more loaded axle is limited by a suspension control component such as a valve or solenoid or the like that closes upon detection of a hard brake event in order to lock air in the suspension components of the respective axles. This in turn limits the dynamically unloaded axle from lifting, thereby permitting it to contribute more significantly to the braking effort and improving stopping distance.
