Abstract The present invention is one kind of shoe-drum brakes with nultiple-freedom linking shoes and an automatic interval regulating mechanism. The multiple-freedom linking shoes include two linding two-freedom combined shoes, and each of the two-freedom combined shoes has brake shoe hinged to its driving arm, which is hinged to the brake underplate. The interval regulating mechanism is linked with the multiple-freedom linking shoes. The brake has high brake efficiency and stability, obviously improved heat and water degeneration resisting performance, homogeneously distributed friction pair pressure and long service life. The automatic regulation of friction pair interval results in idean comprehensive preformance.
