Abstract: A hydraulic block, the upper side of which is provided with a brake-fluid reservoir which is fixed in place on the front surface and on the rear surface of the block by fastening apparatus/device (arrangement). The front fastening apparatus/device (arrangement) is formed by a tab that projects from the underside of the reservoir, this tab being screwed to the front surface of the block. The rear fastening apparatus/device (arrangement) is made up of a tab, which projects from the rear side of the reservoir and is formed by a hook that is supported by a carrier that is fastened to the rear side of the hydraulic block and forms a support for the tab, as well as a clamp, which connects the tab to the hook.

Abstract: A hydraulic module including a cylinder (2) which accommodates a piston (3) which delimits a chamber (4) which receives the brake fluid. The piston (3) is connected to the electric motor (5) of the module (1) by a recirculating ball screw (6), whose core (61) is fixedly connected to the piston (3) which itself is guided by needles (21) which are parallel to the axis (xx) of the piston (3) and with which notches (351) on the circumference of the piston (3) interact. The piston (3) is a piece, which is formed from a cylindrical body (32) made from anodized aluminum and an outer ring (35) made from steel, which is forcibly mounted on the edge (34) of the piston and is provided with notches (351) with a cross section which corresponds to the effective cross section of the needles (21).
