Abstract: As one of the most critical part of the automobile brake, the brake pad and its wear performance affects
directly the working performance and service life of the brake. The current researches use the small sample tests with
test conditions quite different from the actual working conditions of the brake pad. In this paper, based on the disc brake
simulation test-bed of the automobile, the influence rules of the initial braking speed, braking pressure and friction
surface temperature on the brake pad wear were analyzed. The results showed that, by increasing braking pressure, initial
braking speed or friction surface temperature the wear increased accordingly. The initial braking speed had the most
obvious effect on the wear. The braking pressure had no obvious effect on the wear. Through several supplementary
tests, it is found that, without external heat producer intervention, the wear was significantly affected by the initial
braking speed and braking pressure than by the friction surface temperature. Based on the test data, the empirical
formula of the brake condition parameters and wear were fitted by SPSS software. The results in this study had certain
theoretical significances and practical values for guiding the design, manufacture, use and maintenance of the
automobile brake pad.
