Claim 6:
7. A method for assembling a hydraulic unit, the hydraulic unit including a hydraulic block that has a cylindrical hole in which a piston is axially displaceably guided, a sleeve disposed nonrotatably at a mouth of the cylindrical hole and surrounds the piston, and a rotation prevention element that is disposed between the sleeve and the piston and extends in a displacement direction of the piston, and which holds the piston nonrotatably by positive engagement, wherein a rear end of the rotation prevention element is held in a first receptacle of the sleeve, and the rotation prevention element projects forward out of the sleeve toward the hydraulic block, wherein the sleeve has an inwardly projecting flange having a hole constituting the first receptacle for the rear end of the rotation prevention element and wherein the hydraulic block has a second receptacle for the rotation prevention element, into which a front end of the rotation prevention element is inserted, the method comprising:
fastening the rear end of the rotation prevention element in the hole of the inwardly projecting flange of the sleeve;
disposing the piston in the sleeve;
disposing the sleeve at the mouth of the cylindrical hole in such a way that the front end of the rotation prevention element enters the second receptacle of the hydraulic block for the rotation prevention element, and the piston enters the cylindrical hole of the hydraulic block.
