8.4 Adjustment / readjustment of the friction block distance 
 
The friction block distance is adjusted after mounting the brake caliper by adjusting / readjusting 
with the adjusting screw (3). The distance between the friction blocks and the brake disc on both 
sides should be approx. 0.3 mm when new. If the friction blocks wear out, brake force must be 
adjusted.  When reaching a dimension of "X" = 27 mm (see figure 2.1) at the latest, brake force 
adjustment and adjustment of the friction blocks must be carried out. 

 

 
Attention! 

Before commissioning, the air gap must be set to 0.3 mm on both sides!

 

 

 
 

 
      Caution! Danger of injury! 

When the brake caliper is released, the spring (5) is pretensioned. In the event 
that the electromagnet is not constantly supplied with the correct power supply, 
parts of the brake can suddenly move relative to each other! 

 

Proceed as follows: 

Release the brake by switching on the supply voltage. 

Press a friction block (2) against the brake disc and tighten the screw (6) against the tip of the 
spring guide until the desired total clearance (maximum 0.6 mm) is reached on the other friction 
block (2). Lock the screw (6) with the lock nut. 

 

 

 

Tip! 

The adjustable minimum clearance depends on the lateral run-out of the brake 
disc. The lower the clearance, the greater the wear reserve before the brake 
caliper has to be adjusted. 

 

Depending on the position of the brake caliper and the brake disc axle, the laterally mounted 
electromagnet can generate a tilting torque, which causes an uneven air gap between the two 
friction blocks and the brake disc. In extreme cases, a friction block can even come into contact 
with the brake disc and the entire clearance is set at the opposite friction block.  
The result would be a constant rubbing of this friction block during operation. The air gap can be 
evenly adjusted by means of the set screws (3). Determine which friction block has the larger air 
gap. Turn the set screw on the lever clockwise and adjust an even air gap of 0.2 - 0.3 mm on 
both sides. 

 

 

 

Important:  

It must be ensured that the friction blocks (2) do not rub against the brake disc 
when the brake caliper is open.  

 

If the power supply of the brake is switched off, the full braking torque (holding torque) is 
available.
