1. Insert the stahlbus Bleeder valve in hand wide to the installation site.
2. Protect the caliper with an old rag against leaking brake fluid
3. Now remove the original bleeder screw. Some brake fluid will escape, but this is usually not a problem
4. Now screw the stahlbus Bleeder valve in the caliper. Pay attention to the torque in the manual. Because there are several versions of the valve, also different torques for banjo bolts (12 Nm), conical sealing (standard, 10 Nm) and flat sealing Valves (14 Nm) are indicated.
5.Since the assembly also may have entered some air in the brake system, make your first bleeding process. To do this, open the expansion tank cap, so you can fill in brake fluid. Please note that some brake pumps shoot a small fountain through the reservoir to the top when you press the lever. In this case put the lid loosely upped the ante, or take a rag.
6. Put now a suitable hose (we have a suitable bleeder hose from silicone in the program) on the bleeder valve and insert the hose end into a suitable collecting container. You can also use our vacuum filling and bleeding device. This must be compressed before attaching the hose, so the later pump no pressure may develop and the hose is pushed up.
7. Adjust the bleeder valve now to the position "Bleeding" by opening the upper part relative to the lower part by 1/4 "to ½ turn. For safety, you should hold the lower part with a wrench when turning the upper part. For turning the upper part you will need an 8-key.
8. Now you can pump fluid including any air bubbles from the system with the brake lever / pedal. The valve will open automatically as pressure builds up and closes when the pressure drops again. The annoying on and crackin omitted here logically.
9. Always check the level in the reservoir and top up accordingly.
10.If there are no air bubblesto see more in the hose, you can use the valve (top) close to 8 Nm again.
11. Remove the bleeder hose and put the protective cap onto the valve. Because only the stahlbus dust cap protects the complete valve. The usual rubber caps are not long enough here and also look ugly.
11a If you use our vacuum filling and bleeding device, when pulling the hose through the vacuum even the last drop is sucked from the valve head. A neat and clean thing.
Here you can see a little animation to the bleeding process:
