BC Transit – Air Brake Course

Long Stroke Push Rods
Many new air brake systems are equipped with long stroke
brake chambers. As the name implies, a long stroke
chamber design has a longer pushrod stroke than the pushrod
of a standard brake chamber.
The key advantage of a longer stroke is that it keeps
brakes in adjustment longer (it does not create more
braking force). Note: long stroke push rods should not
be used with regular brake chambers – this could cause
poor brake balance and timing.
Long stroke brake chambers can usually be identified by
square-shaped inlet ports or a name tag on a clamp bolt.
