DS2508 - 1

Nominal dimensions given For caliper dimensions see DS2500 Weight (caliper and thruster) -11kg (thruster only) - 4kg Volume displacement of thruster at 4mm retraction is 5ml Maximum Working Pressure 120 bar The ratings shown on the above graph are based on fully bedded and conditioned brake pads with nominal friction coefficient p = 0.4. For bedding-in and conditioning procedures see Publication Ml060. 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 -0.033. 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. ADVANCED BRAKING TECHNOLOGY

Depending upon the service conditions it may eventually become necessary to replace the hydraulic seals. This is done as follows: (a) Remove thruster from caliper, (b) Unscrew and remove the pushrod. (c) Remove the end cap from the rear of the thruster.(see drawing above) (d) Unscrew M10 bolt, (see drawing above) (e) Gently apply hydraulic pressure at inlet port to ease the piston out of the cylinder, (f) The seal and O Ring can now be replaced on the piston and also the one in the cylinder, (see drawing above) (g) Lightly grease the seals and replace piston and lock in position with M10...
