AMTRAK/KNORR DISC BRAKE STUDY VOLUME I-FINAL REPORT

This report describes the Amtrak/Knorr Disc Brake Study which was developed: (1) To evaluate candidate replacement disc brakes for the Knorr disc brakes presently in use on Amfleet and Turboliner cars. (2) To explain the cause of the loosening of the attaching pins and the excessive wear experienced by the disc-brake friction ring on the Knorr disc brakes. (3) To find out why the disc brake failure rate was much higher when the outside temperature was below 32 degrees Fahrenheit. This report covers the first six months of a three-year controlled revenue service test, an over-the-road test, and laboratory tests to correlate over- the-road test results to pin wear.
