Abstract
A brake shoe has a groove in a support member to receive a dove-tail guide on a brake lining to hold the brake lining on the support member. One longitudinal side of the groove is inclined to define a wedge and the other longitudinal side is straight. Springs are mounted on the support member on the straight side of the groove to extend behind and clamp the brake lining dove-tail guide. Modifications of the groove include inclined sides along only portions of the groove and springs at the straight wall portions of the groove to extend behind and clamp the dove-tail guide of the brake lining.
