Abstract
A dual-motion collar device is described, which elicits an additional motion from an operator when initiating a parking brake release in a vehicle. The collar device comprises top and bottom collars with a compressed and torsionally stressed spring there between, such that the collar device maintains a park brake plunger knob in a locked state. An operator twists the top collar to align interlocking features on the top and bottom collars, and then pushes downward to unlock the collar device. The operator then pushes downward on a park brake plunger knob around which the collar device is installed to actuate a parking brake valve assembly and release the parking brake.
