PCT No. PCT/KR95/00052 Sec. 371 Date Nov. 12, 1996 Sec. 102(e) Date Nov. 12, 1996 PCT Filed May 9, 1995 PCT Pub. No. WO95/31650 PCT Pub. Date Nov. 23, 1995A center brake for automobiles is disclosed. The brake has braking teeth (which may be triangular, trapezoidal or of other shape) formed on the outer surfaces of the brake shoes and on the inner surface of the brake drum for improved brake performance. Preferred brake drum material is cast iron and preferred brake shoe material is non-toxic to avoid health damage to those who come into contact with the brake. The mechanical structure of the preferred brake results in a system which reliably carries out its brake shoe return function even when there is a failure or malfunction of brake return springs or ice on the brake during cold weather. The preferred brake can be alternatively actuated by a switch or lever. |
