High temperatures may be produced after braking on the surfaces of the disc brake and 
the brake linings. Personnel must therefore wait for parts subject to overheating to cool 
down and wear suitable protective gloves and PPE. 

 

9.1.

 

Readjusting the play 

 

1.

 

Power up the thruster (minimum supply pressure of 60 bar and maximum of 100 bar). 

2.

 

Loosen the ring nuts C61711. 

3.

 

Rotate  the  play  adjuster  clockwise  until  the  optimal  play  of  1  mm  (with  disc  of  thickness 

25.4 mm) or 1.5 mm (with disc of thickness 40 mm) is obtained between the disc and each 
brake lining (Figure 2). 

4.

 

Lock the ring nuts C61711. 

5.

 

Realign the brake shoes as described in point 6 of Chapter 7 (Figure 3). 

 

9.2.

 

Changing the lining pads 

 

1.

 

Power up the thruster (minimum supply pressure of 60 bar and maximum of 100 bar) and 

replace the silencer with the safety screw. 

2.

 

Pull out the pin K90073 and remove the shoe D71026 for brakes with disc of thickness 25.4 

mm or the shoe D71023 for brakes with disc of thickness 40 mm. 

3.

 

Unscrew the 4 screws C61171, remove the brake lining and replace it with a new one. Put a 

few drops of threadlock on the screws C61171 and tighten them to a torque of 12 Nm. 

4.

 

Reassemble  the  shoe  following  the  sequence  in  point  2  in  reverse  order,  positioning  the 

shoe alignment spring C61958 as indicated in Figure 3. 

5.

 

Readjust the play between the disc and lining as described in Chapter 9.1. 

6.

 

Replace the safety screw with the silencer. 

9.3.

 

Cleaning the friction surfaces 

 

1.

 

Dismantle the brake linings as explained in Chapter 9.2. 

2.

 

Remove any oil or grease from the surface of the disc using a non-pollutant detergent. 

3.

 

If the discs are contaminated only superficially it is better to clean them using fine emery 
cloth. If the contamination of the linings is deep or at the maximum wear limit as indicated 
in Chapter 5.2 and stated in the catalogue, replace them with new linings. 
 

9.4.

 

Changing the thruster springs 

 

1.

 

Power up the thruster (minimum supply pressure of 60 bar and maximum of 100 bar). 

2.

 

Replace the silencer C61846 with the safety screw TE M14. 

3.

 

Unscrew the ring nuts and remove the thruster from the brake.
