Abstract: A multi-disc brake, in particular for a road vehicle, includes parallel plates which are arranged at a distance from one another and which are rotationally stable and between which a rotatable brake disc is positioned. The radially extending plates and the brake discs can be pressed against one another during braking while overcoming a clearance and once the brake is released, the discs are separated from each other thus forming a clearance. The brake discs are pressed individually in the non-brake position by axially working restoring springs and/or in groups counter to an axially stationary stop, which stop can be rotated with the brake discs.

Abstract: A disc brake includes a brake caliper which engages over a brake disc and which has a caliper head and a caliper back connected thereto by tension struts. Brake pads are received in the brake caliper, are radially secured by a retaining bracket that extends in the axial direction of the brake disc, and can be forced against both sides of the brake disc. The disc brake further includes a measuring device which is connected to an evaluation unit for determining the brake application force and which is designed such that the measuring device has two base elements that can be displaced relative each other in the direction of brake application, one of the elements being a sensor and the other being a corresponding element actively connected thereto. One base element is arranged on the retaining bracket which is clamped on one side of the caliper head or on the caliper back and the other base element is arranged on the brake caliper on the side opposite the side on which the retaining bracket is clamped.
