LINKAGE ASSEMBLY

A linkage assembly couples a plunger of a brake valve to a manually operated brake input member. The linkage assembly includes a pushrod and a resilient member. The pushrod has an end member which is engagable with the plunger. The resilient member is attached to the pushrod end member. The resilient member has an end which is engagable with the plunger when the pushrod end member is spaced apart from the plunger. The resilient member deforms to allow the pushrod end member to directly engage the plunger when the pushrod end member is moved towards the plunger. One of the end and resilient members surrounds a portion of the other of the end and resilient members. The resilient member may be a sleeve which surrounds an end portion of the pushrod. Or, the resilient member may be surrounded by a hollow end portion of the pushrod.
