Abstract

The invention relates to the cylinders of hydraulic drum brakes, making it possible to evacuate excess liquid to the outside by leaks from the cups. It comprises the piercing of the cylinder with a skew hole from each end at the origin of the groove of the internal chamfer, in order to connect the bottom of the hole of each fixing bolt 1; the fixing of the cylinder to the drum flange, by two bolts which are pierced by a hole 2. The piercing of the bolts 2 may be replaced by a flat or a channel for the evacuation of the liquid.
