The Twiflex VS disc brake caliper is comprised of two modules secured between U-shaped top and bottom mounting plates by tie rods.
Typically one or two calipers are used per disc, but the number may be increased depending on disc size. The brakes may be positioned at any angle around the periphery, but ideally mounted horizontally (at the 3 o’clock or 9 o’clock positions).
Minimum disc diameter is 1000mm with no maximum except for practical limitations. The standard caliper can accommodate disc thicknesses from 38mm to 50mm - consult Twiflex for discs thicker than 50mm.
A tandem caliper arrangement is available sharing a common, central, mounting plate; minimum disc diameter is 2000mm.
The ratings shown on the tables are based on fully bedded in and conditioned brake pads with a nominal friction coefficient μ = 0.4. Twiflex disc brakes must be used with Twiflex asbestos free brake pads.
Effective disc radius = actual radius (m) – 0.110m.
Note: Spring fatigue life is a function of the caliper rating.
