THE RESPONSE SENSITIVITY OF AN EXAMPLE ANTILOCK BRAKE SYSTEM TO CHANGES IN LINING FRICTION. TECHNICAL REPORT. VOLUME II: APPENDICES

Full scale straightline brake and brake in turn tests were performed on both high and low mu surfaces with an example automobile equipped with an antilock brake system (ABS). Several different sets of brake pads were tested to measure the effect of brake pad friction level on the response and performance of the example ABS. Preliminary tests were performed to estimate the brake pad friction coefficients, which ranged from 0.27 to 0.45 in the front and from 0.30 to 0.52 in the rear. Similar braking tests were accomplished with a temporary spare tire mounted successively at the front and rear. The results show that there was no systematic effect of varying pad friction on ABS response, and that the stopping distances did not change by a substantial amount over the brake pad frictions tested.
