The Twiflex MS series disc brake calipers are suitable for use with 12.7 mm thick discs. Minimum diameter of the disk: 250 mm.
Normally for each disc one or two calipers are used, mounted horizontally (in a position corresponding to 3 o'clock and 9 o'clock) to avoid wear of the skate caused by the weight of the actuator itself. A wide range of brake discs is available from Twiflex (See Discs and hubs).
For the operation of the pneumatic units it is necessary to use filtered, dry and non-lubricated compressed air. Pneumatic brakes require a manually operated control valve or controlled by an electric or pneumatic signal.
The performances of the graphs referred to the various configurations are intended to be obtained, with well-run shoes and with a friction coefficient equal to µ = 0.4. Twiflex disc brakes must be used with asbestos-free Twiflex brake pads.
Effective radius of the disk = current radius (m) - 0.03 m.
