How do I maintain the SRA vacuum clutch/brake?

The Vac-U-Torq® range of rotary cutters were fitted with a SRA vacuum clutch/brake unit.

Four sizes of clutch were used:

SRA 20, SRA 23, SRA 30 & SRA 36.

These Vac-U-Torq® cutters were manufactured between 1984 & 1999 so spare parts availability is limited.
