Abstract: A disk brake assemblage providing an improved arrangement whereby the brake pads and supports therefore may be changed with a minimum amount of disassembly of the disk brake assemblage. The brake assemblage is provided with an annular cylinder and an annular piston operable therein and comprising a brake cylinder device operably disposed between a pair of backing plates and brake pads which are adapted to frictionally engage respective brake disks or rotors. Both the cylinder and the piston are provided with axially projecting lugs or members normally engaging correspondingly formed recesses on the brake pad backing plates for retaining the brake pads and plates in the operable position. By axially squeezing or displacing the cylinder and piston toward each other, the lugs are displaced out of the recesses to permit the brake pads and backing plates to be removed and replaced.

Abstract: A full disk brake including a pair of disks, brake pads, and a closed external housing. In order to facilitate removal of the housing for changing brake pads, the housing is segmented, such as in the form of a pair of semi-cylindrical segments which are secured to the respective peripheries of oppositely facing disks. The housing segments may be removed independently of the brake actuating mechanism, that is, the wheel cylinder, to permit the pads to be changed. The housing segments may also be mounted such that they may be partially unsecured and then swung out of the way of access to the brake pads.

Abstract: A device for regulating the traveling speed of a motor vehicle, comprising an electric regulator acted upon by a speed-responsive signal, which regulator compares the prevailing travel-speed with a prespecified desired traveling speed and, in the case of a deviation of the actual traveling speed from the prespecified one, emits a signal proportional to the deviation variable. The device comprises a pneumatic adjusting drive, preferably the accelerator, which acts upon an element affecting the ratio between fuel and air in the fuel-air mixture fed to the motor vehicle engine. The adjusting drive is in turn acted upon by a vacuum or excess pressure or normal pressure by way of a control stage which is responsive to a signal emitted by the regulator.
