Abstract Preview

ISO 20918:2007 describes a method to evaluate the braking threshold of heavy commercial vehicle combinations with pneumatic braking systems, by means of a roller brake tester.

ISO 20918:2007 describes procedures for workshops and garages and provides

  • a recommended pressure range of the system threshold pressure for motor vehicles and trailers, and
  • a recommended practice for determining the system threshold pressure.

ISO 20918:2007 covers neither high-pressure compatibility, including the control of the coefficient of friction between lining/pad and drum/disc, nor dynamic influences. ISO 20918:2007 is not for use at Type Approval.
