3 Brake replacement
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.
B - Brake fitment
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.
NOTE
: if fitting a new brake assembly, the transit plug must be
removed from the Actuator seal (30) before fitting the Air Actuator.
NOTE
: if replacing the original brake assembly, remove the
adhesive tape from the air actuator mounting aperture.
Lightly grease the operating shaft pocket with the appropriate
grease. Fig. 18
WARNING
Only use the grease supplied with replacement
components/kits. Under no circumstance should any other
type of grease be used.
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.
Initially tighten the 2 nuts to a pre torque of 80 –100 Nm,
(this ensures the actuator seals and does not distort the non
pressure plate). Apply a final torque of 180 – 210 Nm
Refit the pads as described in the section 2 "Pad replacement"
Refit the PWWI where appropriate.
