Abstract: A friction lining assembly having a backing plate and a sheet metal restoring spring fixed thereto, for a partially lined sliding-caliper type disk brake having a brake holder fixed with respect to the vehicle, on which friction lining assemblies arranged on both sides of a brake disk are slidably guided. A housing, which extends over the brake disk and the friction lining assemblies, is slidably mounted on the brake holder. The restoring spring is clamped axially between the brake holder and the friction lining assembly by at least one spring leg and applies a release clearance to the friction lining assembly. The spring leg extends over a hammer-head-shaped claw of the backing plate. The spring leg is plastically deformable in a defined manner under braking actuation as a result of a reduction in the friction-material thickness in order to impose a constantly dimensioned release clearance on the friction lining assembly.

Abstract: A method is provided for measuring parameters of state of a fluid contained in a container (10, 10?) that has a sensor carrier plate with plural sensors (S01-S10, S01?-S10?). Each sensor has a sensor head in operative contact with the interior of the container (10, 10?) and in operative contact with an external control unit (12).

Accordingly, the force flux in the holder is closed, and in the case of pull suspension all the holder arms are nevertheless included in the force flux.
