A supplemental braking system mounted on a vehicle’s driveline provides a redundant stopping mechanism, typically for added safety in situations where primary brakes might fail. This system often employs a caliper-like device clamping onto a rotor or drum attached to the driveshaft, creating friction to slow the vehicle. Common applications include heavy-duty trucks, trailers, and off-road vehicles where steep grades or heavy loads increase the risk of brake fade or failure.
Redundant braking systems offer increased safety and control, especially in challenging driving conditions. They provide a backup stopping mechanism, reducing the risk of runaway vehicles and potential accidents. Historically, these systems have been crucial for heavy vehicles operating in mountainous terrain or carrying substantial loads. Their presence can enhance driver confidence and provide a critical safety net. Furthermore, in certain commercial vehicle applications, these systems are mandated by safety regulations.
