Abstract

The invention concerns a simple device for bleeding disk brakes. The invention concerns a device for bleeding disk brakes (1) and drive out air bubbles with no possible return into the braking circuit so as to guarantee the safety of the braking system and provide simple implementation. It consists of a transparent flexible tube provided with its integrated non-return system (2) which is driven on a bleeder valve nozzle of the brake caliper (3). After opening the bleeder valves, several depressions on the brake pedal (4) will eliminate the old brake fluid with no possible return thereof. After gradually filling the brake fluid reservoir with new product and several depressions on the brake pedal the new fluid will fill up the whole circuit to appear at the tubes (5) exempt of any air bubble. Then the bleeder valves are simply closed and the inventive device cast away.

Une personne seule peut faire ce travail, elle est sûre de ne pas avoir d'air dans le circuit de freinage, et a la certitude d'avoir un circuit complètement vidangé à neuf sans restes résiduels de l'ancien liquide. La sécurité pour le conducteur est augmentée. Le gain de temps est considérable le travail est sûr, propre et de qualité. L'économie en temps, coût, et main d'œuvre est importante. La matière première constituant le petit kit objet de cette invention est très économique et jetable. L'invention est extrêmement simple, elle consiste en l'apport d'un tuyau transparent muni d'une petite buse enfoncée dans le dit tuyau empêchant le reflux des liquides ou de l'air que l'on souhaite extraire. Cette buse logée dans son tuyau transparent laisse passer les liquides dans un sens et en empêche le retour. La buse est faite en deux parties, un petit manchon plastique résistant aux produits corrosifs dans lequel se trouve un petit cône plastique qui est libre à l'intérieur et se déplace d'avant en arrière, dans le sens de la sortie du liquide, le petit cône laisse le tuyau ouvert dès qu'il y a un reflux ou aspiration le petit cône se bloque sur la buse et empêche tout liquide de revenir. Ce tube souple transparent s'adapte sur les gorges d'ouverture de vidange des étriers de frein par enfoncement et tient facilement le temps de l'opération. Le tuyau peut-être de différents calibres selon la taille de l'étrier de frein s'il s'agit d'un camion ou d'une voiture. La longueur du tuyau est d'environ 50 cm pour permettre au liquide de bien s'engager hors des étriers sans en faire tomber si l'on en est à l'opération de remplissage des circuits de frein où il n'est plus nécessaire de vidanger le circuit. Sa longueur lui permet en cas de vidange complète de pouvoir déverser ce liquide dans un récipient et ne pas mettre en contact les éléments de la voiture avec ces liquides corrosifs. La buse et son élément intérieur sont en matière plastique fabriquées en une seule opération de moulage par injection. Le tube est en matière plastique transparente résistante aux hydrocarbures.A single person can do this job, she is sure to have no air in the brake system, and is certain to have a completely drained circuit nine without residual residues of the old liquid. Safety for the driver is increased. The time saving is considerable the work is safe, clean and quality. The economy in time, cost, and labor is important. The raw material constituting the small kit object of this invention is very economical and disposable. The invention is extremely simple, it consists in providing a transparent pipe provided with a small nozzle pressed into said pipe preventing the reflux of liquids or air that is to be extracted. This nozzle housed in its transparent pipe passes the liquids in one direction and prevents the return. The nozzle is made in two parts, a small plastic sleeve resistant to corrosive products in which there is a small plastic cone which is free inside and moves back and forth, in the direction of the exit of the liquid, the small cone leaves the hose open as soon as there is a backflow or suction the small cone hangs on the nozzle and prevents any liquid from coming back. This transparent flexible tube fits on the opening grooves of the brake calipers by depression and easily holds the time of the operation. The hose may be of different caliber depending on the size of the brake caliper if it is a truck or a car. The length of the pipe is about 50 cm to allow the liquid to engage well out of the stirrups without dropping it if one is in the operation of filling the brake circuits where it is no longer necessary to drain the circuit. Its length allows it in case of complete emptying to be able to pour this liquid into a container and not to put the elements of the car in contact with these corrosive liquids. The nozzle and its inner member are made of plastic material manufactured in a single injection molding operation. The tube is transparent plastic material resistant to hydrocarbons.
