Abstract
For automobile drum brakes of the simplex and duo-duplex forms of construction, each having two brake shoes (10) floatingly mounted on a brake bracket (1), a special support is proposed for the one end of the brake shoe web (10) of each brake shoe (8), this support being constituted basically of a support pin (26) rotatable about its central axis, which possesses a recessed bearing surface, on which a corresponding counter-surface (35) of the brake shoe web (10) is slidably journalled. The new support makes possible the maintaining of a constant brake coefficient throughout the full range of wear of the brake lining (12).
