Figure 13 6. Once the components are rotated to the desired position,
re-clamp the unit. Pay special attention to the seating of
the diaphragm, making sure it is centered and flush to the
housing all around. Push the service side housing onto
the diaphragm and put the clamps back on. Install clamp
hardware, and hand tighten the nuts. Alternately tighten
the nuts with a wrench so the distance between the clamp
ears are equal on both sides (Figure 13).

final torque to the clamp nuts. With a torque wrench, apply

(Figure 14).
IMPORTANT: As final inspection, verify the clamp
ears are equally spaced on both sides.
Otherwise, it is possible for one side to
have too much gap to achieve proper
sealing. Unbalanced clamp ear gaps
increase the likelihood of a leak.
4. Mechanical Release of Spring
Brake (Caging) All Types
4.1 Caging The Spring Brake
IMPORTANT: DO NOT attempt to mechanically release
(cage) the spring on any spring brake that
shows sign of structural damage, significant
corrosion or any other damage that the
operator or mechanic deems unsafe.
Failure to handle with extreme caution
or attempting to disassemble the
damaged spring brakes could result in a
forceful release of the chamber and/or its
components which, if not avoided could
cause death or serious injury.
1. Remove the dust plug from the release tool access
hole in the center of the spring housing as illustrated
(Figure 15).
2. Remove the release tool assembly from its holder on
the adapter base or from its holder on the spring
housing, not illustrated (Figure 15).
3. Apply vehicle or shop pressure, 120 psi (8.3 bar) 90 psi
(6.2 bar) minimum, to the emergency side of the brake.
Maintain vehicle or shop air pressure. If shop or vehicle
air is NOT available, proceed to Section 3.2.
