NOTE:
Before beginning any axle/brake service procedures,
park the vehicle on a level surface. Block the wheels
to prevent the vehicle from moving. Support the
vehicle and axles(s) with safety stands. DO NOT
work under a vehicle supported only by jacks.
Jacks can slip or fall over. Serious personal injury
and damage to components can result.
Failure to properly support the vehicle
and axles prior to commencing work could
create a crush hazard which, if not avoided,
could result in death or serious injury.

according to the spring brake manufacturer’s instructions.
