GENERAL:
1.1 Description:

• This manual contains the Installation, Operation and Maintenance instructions for
  the Twiflex GMR40-SD disc brake caliper.
• The GMR40-SD disc brake comprises a GMR40 caliper and SD thruster which is
  suitable for a disc thickness of 40mm.
• The minimum disc diameter for both calipers is 610mm but there is no limit on the
  maximum diameter.
• The GMR40-SD disc brake calipers are spring applied, air released and produce a maximum tangential
  braking force of 36 kN at a nominal thruster stroke of 20mm.
• By removing springs from the thruster the braking force can be reduced to 10 kN. The range of
  thrusters use dry and filtered compressed air at pressures from 1.4 to 4.6 bar depending on the spring setting.
• A total of five spring settings are available (see Tables 1 & 2).
• Two types of monitor unit can be supplied.
• The first incorporates microswitches to indicate full retraction and when thruster stroke
  adjustment is required.
• The second incorporates inductive proximity sensors which also indicate full retraction and the
  requirement for thruster stroke adjustment, but in addition provide a signal which can be used to
  initiate system shutdown if adjustment has not been
  made.
