Mark position of expander arm (1) with regard to the shaft (2).
Dismantle arm and set it in the appropriate position.
in direction (A), if braking is too early,
in direction (B), if breaking is too late.
Repeat the process for the second arm.
Replace the pin fixing the cylinder fork.
Adjustment should be conducted separately for each wheel. Expander arm (1) should be
moved by one notch in chosen direction. If the extent of cylinder action is still incorrect, move
the lever again. After proper brake adjustment, at full braking the axle shaft expander should
create an angle of 90
°
with the cylinder piston, and the stroke should amount to approximately
half the length of the total stroke of the piston. After brake release expander arms may not be
supported on any structural elements, because too little withdrawal of a piston ram may
cause abrasion of brake shoes in drum and result in overheating trailer brakes. Expander
arms must be positioned in parallel with regard to each other at full braking. If this is not so,
adjust the position of the lever, which has the longer stroke.
The cylinder fork mounting position is selected by the Manufacturer and may not be changed.
For all the braking systems on this trailer it should be 175 mm, see Figure (5.5).
Checking and adjustment of main brake:
•
every 12 months,
•
if needed.
Brake repairs, changes of brake linings etc. may be only undertaken in authorised service
points. Making unauthorised repairs and modifications by the user voids the guarantee.
Among the service operations which may be performed by the trailer user there is only brake
adjustment by changing the setting of expander arms.
5.2.8 CHANGE OF PARKING BRAKE CABLE AND ADJUSTMENT OF CABLE
TENSION.
Proper operation of the parking brake is dependent on the effectiveness of the axle brake
and the correct brake cable tension.
