1. A hydraulic block arrangement for a hydraulic unit of a hydraulic power vehicle braking system, the arrangement comprising:
a cuboidal hydraulic block having (a) a power cylinder bore in a motor side of the hydraulic block, (b) a main brake cylinder bore extending between first and second fastening sides of the hydraulic block, the first and second fastening sides being opposite each other and being adjacent and perpendicular to the motor side, and (c) a first fastener connecting arrangement at the first fastening side and a second fastener connecting arrangement at the second fastening side;
an electric motor situated at the motor side covering an opening of the power cylinder bore;
a piston rod that is shiftable by a brake pedal or lever; and
a fastener mechanically fastened to the first fastener connecting arrangement at the first fastening side of the hydraulic block;
wherein the fastener:
is configured to also be mechanically fastened to the second fastener connecting arrangement at the second fastening side; and
includes a fastening flange that has an opening therethrough aligned with the main brake cylinder bore and through which the piston rod is passable into the main brake cylinder bore from whichever of the first and second fastening sides to which the fastener is mechanically fastened.
