Functional Testing of Brake Combination Valves

The high level of reliability required of safety-related automotive parts, such as brake control system components, demands thorough functional testing of the component. A highly automated test system now in use at a component manufacturing plant helps to provide this reliability by performing 12 separate tests on each brake combination valve produced. The air test and the 11 hydraulic tests are described, features of test system design and operation are discussed, and the test equipment used is listed.
