The Twiflex VMS3-SPS disc brake caliper is comprised of two modules bolted to
a central mounting plate, 12mm thicker than the brake disc. Minimum disc
thickness is 38mm and minimum disc diameter is 1500mm with no maximum
except for practical limitations. Based on a development of the earlier Twiflex
VMS2-SP disc brake, the VMS3-SPS provides a significant increase in braking
force but in a similarly sized package.
Infinite fatigue life (>2 x 106 cycles) is achievable for most units at the 3mm air
gap shown in the table and possible, by reducing this setting, for the higher
rated brakes – contact Twiflex for further information.
The braking force is a function of both the air-gap setting and the thickness of
the shim pack (if used) but may be also controlled using hydraulic back pressure
during braking.
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) – 0.155m.
Spring applied, hydraulic released modular safety brakes.
