DS1003 MUS2 Disc Brake Caliper - Spring applied Pneumatically released

Product catalog summary
Overview: The document provides technical specifications and assembly instructions for Twiflex disc brake calipers, specifically the MUS2 and MU3 models. It includes details on braking torque, air pressure requirements, and assembly components.
Specifications:
  • Braking Torque: The graph indicates braking torque in relation to air pressure and disc diameter. The ratings are based on fully bedded and conditioned brake pads with a nominal friction coefficient of μ=0.4.
  • Disc Diameter: Ranges from 250 mm to 515 mm.
  • Air Inlet Port: Rp1/4 (1/4" BSP).
  • Weight: Caliper and thruster weigh 1.36 kg; thruster only weighs 0.61 kg.
  • Pressure Requirements: Minimum pressure for full retraction is 4.3 bar. Maximum braking force is 600N.
Procedures:
  • Bedding-in and Conditioning: Refer to Publication M1060 for procedures.
  • Assembly Instructions: Detailed steps for assembling the caliper with the thruster, including fitting the packing washer, spacer, and lock nuts.
  • Diaphragm Replacement: Ensure air supply is disconnected before replacing the diaphragm. Follow specific steps for removal and reassembly.
Components and Spare Parts:
  • Available Spares: Diaphragm Kit (Part No. 7902797), Piston Rod Assembly (Part No. 7200919), Thruster (Part No. 7200923).
Recommendations:
  • Use Twiflex asbestos-free brake pads to maintain warranty validity.
  • Ensure proper maintenance and replacement of components as per guidelines to ensure optimal performance.
Additional Information: Twiflex Limited reserves the right to modify or change the design without prior notice. The document includes contact information for Twiflex Limited in England.

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 -0.02. Twiflex Disc Brakes must be used with Twiflex asbestos free brake pads.The use of any other brake pads will invalidate the warranty.
