The stahlbus®-bleeder valve consists of two parts with a setback function. In the bleeding and filling, only the upper part of the valve is opened, in which an o-ring-sealing is integrated. Through it neither air nor brake fluid or hydraulic fluid can penetrate through the opened thread.
With the bleeder valve we have eliminated some common problems including the synchronizing of the opening and closing process. If there is a drop in pressure, the stahlbus®-bleeder valve closes automatically until pressure is applied again.
The entire bleeding process can be completed in just a few minutes, by yourself, without assistance. Hidden air bubbles are flushed out of the system due to the high volume of fluid forced through the bleeder valves.
The stahlbus®-bleeder valve was tested by the TÜV Rhineland Group (European Quality and Safety Standard) for function and quality and received the highest rating. Brake fluid is just as important for your braking system as brake pads and brake disks! The most expensive and most modern brake system means nothing if air is in the system.
When replacing brake lines, you can open the valve up to one and a half turns and flush the system with a vacuum or with a pressure system. The incorporated o-ring seals the system completely throughout the process.
A - First rotate the upper part of the valve 1 with a half turn to allow the valve to start the bleeding process. Check Valve release 2 out of lock position.
B - By pumping the brake lever/pedal 3 the pressure opens the check valve (ball 2) and all the air and air bubbles 5 are forced out of the brake lines. As soon as you release the brake lever, the pressure is released and the check valve closes immediately. Therefore no air can penetrate into the brake system and only fluid and air can exit.
C - Close the bleeder valve with a half turn. The check valve is secured again. Important: Check the level of your reservoir 6 again! «
A common problem associated with bleeding hydraulic systems, such as brakes, clutches or couplings, is that the conventional bleeder screw let's air in and hydraulic fluid out.
Since the conventional screw typically has inadequate thread thickness, it consistently allows air into the system each time it is turned on and off, resulting in permanent bubbles.
