Abstract
An electromechanical drum brake has a vehicle-mounted brake anchor plate, a wheel-mounted brake drum, a spreader mechanism, which is fastened to the brake anchor plate and is designed to push a leading and a trailing brake shoe of the drum brake away from each other in opposite directions along an active axis and against the brake drum, and a support block, which is fastened to the brake anchor plate, protrudes into the brake drum and forms a first support bearing for the leading brake shoe and a second support bearing for the trailing brake shoe. In this case, the first support bearing and/or the second support bearing are/is formed in each case by a strain-sensitive sensor unit.
