A brake pad friction lining having, as required by UIC regulations for use on railways in Europe, a coefficient of friction under wet conditions not less than 85% of that under dry conditions, comprising a fibre-reinforced matrix of organic polymeric material which includes non-fibrous particulate material serving as friction or wear modifier or filler. The organic polymeric material employed according to the invention comprises cured high-hysteresis elastomeric material, for example a high-styrene/butadiene rubber, in a proportion by volume of the lining which is high enough to ensure a loss angle of at least 13 DEG therein.
