| BRAKE LINING TEMPERATURE TESTS - BENTLEY TESTS CARRIED OUT ON 3 B.V. FERODO M.Z. LININGS. BRASS RIVETS IN CONTACT WITH DRUM. STEEL SHOES. TEMPERATURE MEASURED BY THERMO-COUPLES IN CENTRE RIVET OF LEADING SHOES ON NEAR SIDE WHEELS. REAR BRAKES FRONT BRAKES Y-AXIS: BRAKE LINING TEMPERATURE X-AXIS: DISTANCE - MILES (SEE NOTE 2) NOTE 1: THE TEMPERATURES RECORDED ARE THE MAX: READING AFTER EVERY HEAVY APPLICATION OF THE BRAKES. THE TEMPERATURE IMMEDIATELY BEFORE THE APPLICATIONS IS NOT SHOWN. NOTE 2: THE DISTANCE SCALE IS APPROXIMATE ONLY. THE READINGS ARE SPACED AT REGULAR INTERVALS ON THE CURVE WHEREAS ACTUALLY THEY OCCURRED AT IRREGULAR INTERVALS.
