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.
