Adjustment of ‘pad wear’ switch 

 

This switch is permanently closed and opens when the pad wear reaches 1mm. 

 

-  Power the brake with opening pressure 

-  Check that the pads clearance is correctly adjusted, otherwise proceed to adjustment. 

-  Brake being open, check that the connection pin 

22 

is in contact onto lever 

42. 

-  Cut off pressure to close the brake.

 

-  Unscrew nut 

V11

 then adjust screw 

V02 

Allen wrench to free it from the switch end

 

(adjust the screw 

skimming the lever). 

- 

 Adjust the screw HC 

V02

 until the switch triggers (status « worn pads »). When the pads will reach a 

1mm wear, the switch will release as the hysteresis of the switch is 1mm.

 

-  After an adjustment is finished, do not forget to 

retighten nut 

V11 

on the screw 

V02

.
