ABSTRACT:
There is described a brake shoe for a ring type brake which means it has a cylindrical brake ring secured to a member to be braked. The brake shoe comprises a part-cylindrical, preferably sheet metal support plate having on one face a brake lining and on the opposite face an elongate rib extending generally between opposed edges of the support plate and having a substantially flat bearing surface. Preferably the rib is stamped in the sheet metal support plate and receives a complementary portion of the brake lining material therein. The rib may be disposed cordally of the support plate or parallel to the generatrices thereof. Two such ribs may be provided on a support plate parallel to each other though spaced at different distances from median plane thereof. The contact areas of the substantially flat bearing surface with the piston of the hydraulic unit associated therewith are preferably dissymmetrical about one or both of the median planes of the brake shoe. The hydraulic unit may also have two pistons each coacts with the rib(s). Both brake shoes for such a brake may be provided with such flat bearing rib(s).
