Abstract
A tandem master cylinder comprising a first plunger mechanically connected to a foot brake pedal and a second plunger separated from the first plunger to define one of the two fluid chambers. A T-shaped intermediate member provided with a retainer head is interposed between two plungers so as to limit the spaced distance therebetween and mount a return spring on the retainer head abutting the second plunger. The retainer head is of a reduced diameter thereby providing an annular gap between the retainer head and the inner wall of the cylinder body. Thus undesirable injury to the inner wall due to radial displacement of the retainer head will be avoided.
