  • Page 10: Installation

    5020-M Owner's Manual Kobelt Manufacturing Co. Ltd. NSTALLATION REPARATION The foundation plate to support the brake caliper must be designed to withstand the maximum braking forces generated by the brake caliper. The foundation must also be flat to ISO tolerance grade IT8 and square to the brake disc. See Appendix A for key installation dimensions.
  • Page 11 5020-M Owner's Manual Kobelt Manufacturing Co. Ltd. The disc mounting bolts used must be of a suitable size and grade to safely resist the brake torque plus the stresses induced from thermal expansion of the disc. For high temperature disc applications, the holes for the mounting bolts must be machined oversized to allow the disc to expand during operation.
  • Page 12: Caliper Brakes

    Lower the brake down and tighten the mounting bolts to the recommended preload. 3.3.2 Instrumentation Kobelt caliper disc brakes may be equipped with a release indicating proximity switch (part number 6001-3711). The connection to the switch must be made with a 3 pin – M8 cable.

  • Page 14: Torque Test

    5020-M Owner's Manual Kobelt Manufacturing Co. Ltd. Reference section 5.2 for instructions on manually operating the brake. Disc temperature must not exceed 700°F (371°C) or permanent degradation of the lining may occur. Burnishing is best achieved by applying the maximum torque and minimum speed that the drive can tolerate.
  • Page 15: Operation

    5.1.1 Disc Temperature The Kobelt brake lining achieves maximum friction at 300°F. Over 300°F the brake begins to fade or experience diminishing friction. The maximum operating temperature of the brake linings is 700°F [371°C]. Temperatures in excess of this limit will permanently damage the linings and require replacement.
