<p>A caliper brake set engages a brake disk on a machine shaft or drive sheave to hold an elevator car in place at a landing. Brake shoes (20) are pivotally mounted about pins (22) ,with coil springs (24) urging the shoes (20) against stops (23) ,so that the brake pads (26) remain substantially parallel to the side surfaces of the brake disc,thereby preventing tilt and drag of the pads (26) on the disc when the brake is released. <IMAGE></p> |
