A tie rod () for mounting a booster and the brake control master cylinder on a bulkhead () of the vehicle engine compartment. The tie rod () comprises, at each of its ends, a shoulder () defining a bearing surface having a frustoconical shape. Each shoulder is situated in such a way that a narrow part of its frustoconical surface is near a threaded part () used to secure the booster and is located inside of the booster in such a way that each frustoconical surface is in contact with a corresponding frustoconical hole () in a wall of the booster.

Tie rod for booster and booster comprising such a tie rod

A braking device and a method of manufacture of such a braking device. The braking device has a booster () formed of a cover () and of a cylinder (). A central orifice () is formed on the cylinder. A master cylinder () has a body () that partially enters the booster via the central orifice. The master cylinder is fixed to the cylinder of the booster by plastic deformation of a hollow shaft (). The hollow shaft borders the central orifice and extends towards the outside of the envelope and penetrates at least one orifice made in an exterior surface of the body of the master cylinder. The cylinder has a flat face that surrounds the central orifice such that a flange () extends radially towards the outside of the body of the master cylinder and bears more or less flat against the flat face of the cylinder.
