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.

Effective disc radius = actual radius (m) – 0.155m.

The Twiflex VS disc brake caliper is comprised of two modules secured between U-shaped top and bottom mounting plates by tie rods.

The Twiflex VKSD disc brake caliper is comprised of two halves, or spring modules, and is suitable for use with a minimum disc thickness of 20mm. The modules are mounted each side of a central mounting plate 12mm thicker than the brake disc. Minimum disc diameter is 1000mm.

The Twiflex VCS Mk4 disc brake caliper is comprised of two halves, or spring modules, and is suitable for use with a minimum disc thickness of 20mm. The modules are mounted each side of a central mounting plate of the same thickness as the brake disc. Minimum disc diameter is 500mm.
