Commercial Vehicle Systems Product DATA PD-415-200 Function This range of Spring Brakes is used on axles fitted with air disc brakes and provides the service and parking brake functions. The internal wind off mechanism allows the parking brake force to be removed if air pressure is no longer present. The Spring Brakes have a mounting seal integrated in the non-pressure housing which prevents the entry of dirt or water into the disc brake caliper. See PD-413-000, Document No. Y115384 for the full range of Spring Brakes for trailers. Technical Features Maximum operating pressure: 1 bar Full hold-off pressure: 5.5 bar Operating temperature range: -40 C to +80 C Sealing of secondary chamber: Rubber Boot Push rod stroke: See table Port threads: M16x1.5 Release device: Mechanical Weight: See table Standard Symbol as DIN ISO 1219 11 12 BX 7... 1

PD-415-200 Product Data Winding-off the Power Spring 1 2 3 4 5 In case of failure in the air system, to release the actuator s spring force: Ensure wheels are chocked. Remove release bolt from its holder (Figs. 1 & 2) Unclip closure cap (Fig. 3). Fully insert T end of the release bolt into the spring portion and rotate to engage in the internal slot (Fig. 4) Fit washer and nut. Rotate the nut (19 mm AF) in a clockwise direction (Fig. 5). Max. torque 68 Nm. Attention: Attention: Use only the correct sized ring or open-ended spanner! The parking brake portion of the Spring Brake contains a very high spring load and it is strongly recommended that you do not attempt any disassembly of this portion. This should also be taken into consideration when disposing of spring brakes of any type. Revision Details Rev. 003 March 2011 Format changed to new layout and part number list revised.
