The master cylinder of your Renault is a car part located in the engine. It is generally accompanied by a small tank in which the brake fluid is stored.
This metal part makes it possible for the pressurised brake fluid to flow towards the brake calipers or the wheel brake cylinder of your Renault. Thus, it is possible to brake by keeping the pressure onto the brake pedal.
