CAUTION
When lifting the Brake assembly avoid trapping fingers
between the Brake housing and carrier which are free to
slide relative to each other. Also prevent any sudden
movement, which may result in rapid sliding of the
components, which may cause damage to rubber dust
excluder areas.

Ensure all mounting faces are clean and free from corrosion.
With the help of an assistant, carefully lower the Brake assembly
into position on the axle mounting.
Avoid excessive movement of the Brake during location and do
not allow the Brake to drop into position on the axle, either action
could result in damaged to the slide pin dust excluders.
Fit new fixing screws and torque to the vehicle manufacturers
recommendations.

lug must be
removed from the Actuator seal (30) before fitting the Air Actuator.
NOTE

adhesive tape from the air actuator mounting aperture.

components/kits. Under no circumstance should any other

Offer the air actuator to the housing assembly ensuring the
mounting faces and push rod are clean and the push rod is
correctly located in the operating shaft pocket.
