DS1507 MSK Disc Brake Caliper - Spring Applied, Pneumatically Released Nominal dimensions given For caliper dimensions see DS1500 Disc Thickness Weight (caliper and thruster) - 4.9kg Weight (thruster only) - 3.4kg Volume displacement of thruster at full retraction = 0.95 l. Maximum working pressure 7 bar 2 Maximum Braking Force - kN Minimum Pressure for Full Retraction - bar Braking Torque Nm - Full Rate The ratings shown on the above graph are based on fully bedded and conditioned brake pads with nominal friction coefficient μ= 0.4. For bedding-in and conditioning procedures see Publication M1060. Braking Force is defined as the Tangential Force acting on the brake disc at the Effective Disc Radius. Braking Torque (Nm) = Braking Force (N) x Effective Disc Radius (m) where Effective Disc Radius = Actual Disc Radius -0.03. Twiflex Disc Brakes must be used with Twiflex asbestos free brake pads. The use of any other brake pads will invalidate the warranty. Twiflex Limited reserves the right to modify or change the design without prior notice.

Pneumatic brakes require a control valve which may be operated either manually, or by pneumatic or electrical signal. Should it become necessary to replace a diaphragm, Remove from caliper and ensure air supply is disconnected. Unscrew and remove push rod. Remove the M5 bolts and the rear cap of the thruster. Remove the worn diaphragm; clean-up the contacting surfaces and re-assemble with...
