The Twiflex T40 disc brake caliper is split caliper design 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 300mm.

Normally 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 of the disc. A range of brake discs is available from Twiflex.

The ratings shown on the graph 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) - 0.045m.
