Designed for heavy-duty military vehicles, the MB-21 brake pump is a compact alternative to single-stroke, air-over-oil brake actuators. Its stall capability allows the pump to stall and hold for days with drive air initiated. The reciprocating air-drive ensures complete brake actuation for any size or number of calipers or drums. It is ideal for use on prime mover or large scale trailer and truck brake circuits, ABS systems, brake pilot pressure boost systems, and brake actuation and release systems.
