Fixing of a brake-fluid reservoir

A brake apparatus comprising a brake master cylinder having a longitudinal axis and including an upper portion and, on the upper portion, a central mounting lug located on the longitudinal axis, and a brake fluid reservoir including at least two lateral mounting lugs (10, 11) on either side of the central mounting lug (20) of the master cylinder, the lateral lugs having faces in contact with the central lug of the master cylinder, the lateral lugs including two collinear holes (12, 13) receiving a mounting pin (3) passing through the lateral lugs (10, 11) and the central lug (20) of the master cylinder, and the lateral lugs including at least one device for the axial immobilization of the mounting pin (3), characterized in that the holes (12, 13) in the lateral lugs (10, 11) include wider sections (14, 15) located on the side of the faces of the lateral lugs which are in contact with the central lug of the master cylinder, the wider sections confining the mounting pin in the holes.

A mounting device for mounting a brake fluid reservoir on a support device, the mounting device comprising at least two lateral mounting lugs (10, 11) designed to be placed either side of a central mounting lug (20) of the support device, the said lugs including two collinear holes (12, 13) designed to receive a mounting pin (3) itself designed to pass through the lateral lugs (10, 11) and the central lug (20) of the support device, the said lugs including at least one device for the axial immobilization of the mounting pin (3), characterized in that the holes (12, 13) in the lateral lugs (10, 11) include wider sections (14, 15) located on the side of the faces of the lateral lugs which are designed to be in contact with the central lug of the support device, the said wider sections being designed to confine a mounting pin placed in the said holes.
