Caution:
Before starting work, the counterweight and elevator car must be
secured against uncontrolled movement. The installation must be de-

1.) Removing the brake shoes:

Unscrew the nut at the spring collar and remove disc and compression
spring.

Remove the locking ring at the brake shoe pin.

Remove brake shoe and refit the adjusting screw for the brake actuating
lever and test switch actuation at approx. the same distances on the new
brake shoe.

Install a new brake shoe on the machine.

Reseat or bed in the lining to 75% contact area of the lining surface.

Align brake shoe laterally. The adjusting screw for brake shoe stroke
should be aligned to the middle of the roller at the brake actuating lever.
If offset, remove the brake shoe and align to the roller centre by
rearranging the spacer washers at the shoe bearing. (Washer thickness
1 mm.)

Screw compression spring and spring collar with nut onto the guide bolt
until the brake lining is against the brake disc.

Tighten nuts, see 7.6 Setting initial tension distance
Important:
The test switch screw must not touch the switch contact, or only
very lightly, because otherwise the switch will be damaged.
2.) Setting the brake shoe stroke:
With the solenoid actuated, the air gap between brake disc and brake
lining should be
0.5 mm

Set stroke as described in Chapter 7.3

Change and set the second brake shoe in the same way.
3.) Setting braking deceleration
Set the deceleration as described in Chapter 7.6.
4.) Setting the brake test switches
Set the brake test switches on the brake shoes as described in
Chapter 7.6.
5.) Checking the settings on the replaced shoes

After replacement, operate with electrical recall and observe whether
both brake shoes open evenly.
Important:
After every brake shoe change, the shoe stroke, braking
deceleration, setting and operation of the test switches must be checked and
corrected if necessary.
