Abstract: A foot brake valve (2?) of a pneumatic brake system in a motor vehicle has an installation plate (4?), on which a brake pedal (14) is pivotably mounted and to which a housing (18?) of a control unit (16, 26) is fastened. A spring-loaded plunger piston (36) in actuating contact with the brake pedal (14) is guided axially movably in an annular collar (50) projecting upward out of the installation plate (4?). For fastening the housing (18?) of the control unit (16, 26) to the installation plate (4?), the housing (18?) has an intermediate flange (48) which is screw-connected to the main part of the housing (18?) and has the annular collar (50). The intermediate flange (48) is coaxially rotatably about a vertical central axis (32), and is connectable in non-positively locking fashion to the installation plate (4?) via a releasable clamping connection (62).
