This invention pertains to a compression spring supported plate assembly which carries a friction lining for coaction with an arrestment surface and which is supported a predetermined distance away from a movable base structure. The precompression of the springs can be altered to change the brake force, acceleration, independently and without affecting the distance of the brake lining from the base structure. Correspondingly the distance of the brake lining from the base structure to compensate for brake wear can be altered without affecting the precompression of the springs.
