ABSTRACT:
A brake having first and second brake support means; a brake shoe mounted on each support means intermediate the ends of each support means, each support means pivotably being mounted at one end to a fixed frame, a first spring means mounted to the other end of the second support means biasing the first and second support means, and thus the brake shoes toward each other in a braking action. First actuating means are connected to the second support means and act against the first spring means to maintain the brake shoes in a non-braking position and selectively operable to release the first spring means. A third brake support means is pivoted to one of the first and second brake support means, the third brake support means being also connected to one of the brake shoes. Second actuating means are connected between the third support means and the one of the first and second support means, the second actuating means selectively being operable to move the brake shoes to a braking position independently of the first spring means.
