BRAKE LINING

摘要

PROBLEM TO BE SOLVED: To provide a brake lining that selects and applys an abrasive such that aμ-V negative gradient becomes larger at a brake start speed and smaller immediately before stopping. SOLUTION: In the brake lining of a caliper brake for an automobile brake that includes a friction conditioning agent, a fibrous base material and a bond, a layered structural abrasive satisfying the formulas below is used as a part of the friction conditioning material, and a combined total of 5 volume % or more of the layered structural abrasive ALand a granular abrasive APare included. When f(v) is denoted for scratch resistance by the abrasive, d (v) is for shearing resistance of the abrasive itself, and v is for speed, at the time of brake start, d (v)>f (v),Δf (v)/Δv<Δd (v)/Δv, d (v)=f (v) at a sliding speed of around 2.5 m/sec., and d (v)
