Abstract: A wheel hub and removable bolt ring assembly for air disk braking system includes a hub cylinder, a bolt ring, a locking collar, a plurality of L-shaped locking recesses, and a plurality of rotor mounts that are concentrically positioned around a central axis. The plurality of rotor mounts is positioned adjacent to an outboard end of the hub cylinder. The plurality of L-shaped locking recesses radially traverses into the hub cylinder. The bolt ring and the locking collar are positioned in between the outboard end and an inboard end of the hub cylinder. A plurality of locking splines of the bolt ring is removably mounted around the hub cylinder through the plurality of L-shaped locking recesses. A plurality of locking tabs of the locking collar is removably mounted around the hub cylinder through the plurality of L-shaped locking recesses.

Abstract: A sealed hydraulic stop valve for caliper guide system of an air disk brake system provides a means of continuous maintenance and lubrication. The system includes a tubular guide pin, a cap, a sealed hydraulic stop valve, and a plurality of lubricating grooves. The tubular guide pin attaches a caliper head to a carrier of the air disk brakes. The lubricating grooves inject grease into the system and are radially distributed about the tubular guide pin. Each lubricating groove normally and externally traverses into the tubular guide pin. The cap and the stop valve seal off the tubular guide pin and allow for grease injection to the lubricating grooves. The cap is concentrically positioned about the tubular guide pin. The stop valve is adjacently integrated into the cap, opposite to the tubular guide pin. Resultantly, the stop valve is in fluid communication with each of the lubricating grooves.
