FIELD: transport engineering. SUBSTANCE: invention is designed for fastening friction linings to support plates in friction-action mechanisms. According to invention, friction lining 12 is secured on brake shoe 11 by large number of key members 16 held by screws 17 to brake shoe 11 and interacting with large number of grooves 18 in lining 12 to prevent separation of liquid 12 form brake shoe 11. Key members 16 are held inside grooves 18 to provide limited relative displacement between lining 12 and brake shoe 11 in any direction or no displacement at all. EFFECT: improved reliability of friction mechanism, increased service life of said mechanism. 7 cl, 5 dwg
