What does coupling the brakes mean?

Coupling the brakes refers to locking the two brake pedals together, a practice commonly used in vehicles where dual braking systems exist, such as on trucks or large construction vehicles. This ensures that both pedals operate simultaneously, providing a more balanced and effective braking response. By locking the pedals together, it enhances maneuverability and control, especially when navigating difficult terrains or operating heavy machinery.

The synchronization of brake pressure, calibration of brake sensitivity, or connecting trailer brakes to the vehicle all involve different aspects of braking systems but do not specifically define the process of coupling the brakes. Synchronizing brake pressure relates to ensuring consistent force is applied across all braking systems, while calibrating sensitivity deals with adjusting how responsive the brakes are. Connecting trailer brakes to a vehicle concerns hooking up additional braking systems for trailers, which is a separate consideration in vehicle operation.
