1. A hydraulic block for a hydraulic power brake system, the hydraulic block having a power cylinder bore which is open on a first side of the hydraulic block, and a tubular cylinder cover which extends the power cylinder bore is disposed on a second side opposite to the first side of the hydraulic block, the cylinder cover being connected to the hydraulic block in a pressure-tight manner using a circumferential caulking, wherein the hydraulic block has a greater coefficient of thermal expansion than the cylinder cover.
