15.5 Multiple disc brake, support arm
The brake is an analogue electromagnetic multiple disc brake, that is
the brake is applied by energising the magnet coil. The current in the
magnet coil is regulated by a potentiometer in the brake pedal and
thereby regulates the braking force. The multiple discs are of steel. The
brake acts as a secondary travel brake and is applied when the driver
needs to brake heavily, >50% of the available braking force.
The brake is assembled inside the support arm wheel on a hub with
splines and a locking heel that takes up the braking force.
The support arm wheel must be dismantled from the truck to check and
maintain the brake, see C-code 3550, except when inspecting the actu-
al magnet coil, which can be done with the wheel fitted. All instructions
given below assume that the wheel has been dismantled.

15.5.1 Assembling

• Check that the brakes apply and releases as they should. Connect
the brakes to 48 V D.C. Switch the current on and off.
• Check that the play between the end plate (6) and pressure plate (2)
is 1.0-1.25 mm with the current switched on (brakes applied). The
play may need to be adjusted, see section adjustment.
NOTE!
Check the play at the same time in two positions at 180 degree spac-
ing.
• Fit the brake in the support arm wheel. Make sure that the inner disc
splines are aligned correctly so that they go on the splines on the
wheel hub without resistance.
• Assemble the wheel in the support arm according to instruction C-
code 3550.
Ensure the locking heel (8) is positioned in it cut-out in the support
arm.
• Connect the brake cable (14) and check the brake function by press-
ing down the brake pedal fully.
