A valve support for a hydraulic electronic control unit (HECU). The support includes a flat side (30a; fig. 6) and a stepped side (30b; fig. 6) forming thicker 30.1 and thinner 30.2 parts. A first through bore 5 in the thicker part is for a motor shaft 2.1 of an electric motor 2. On the stepped side, holes 7.1.1 in the thicker part are for actuation valves, with holes 7.2.1 in the thinner part for modulator valves. A first ECU 40.1 is to be located on the thicker part to operate the actuation valves and a second ECU 40.2 on the thinner for the modulation valves, the two ECUs being included to limit the spread of circuit board electrical corrosion. There may be a second bore on the flat side in the thicker part for a piston 8.1, a third bore (14.2; fig. 9b) on the flat side in the thinner part for a pedal feel simulator (14; fig. 10b) and a fourth bore (15.1; fig. 9a) on a perpendicular lateral side for a tandem master cylinder 15. Also claimed is a HECU and braking system including the valves support and methods for producing the valve support.
