extended clutch line install - easy Qs

[jrusell]

I don't pull the lever completely in. Just a few mm in and release. You will see bubbles come out the reservoir. Be careful it will splash, so just barely squeeze the lever.
Before you put any fluid in the reservoir pry the brake pads as far apart as possible on both front callipers. By pushing the caliper pistons back into the bore the fluid will go back up the line and a lot of the air will come out. If you are lucky you might get all or most of the air out this way.

Using a screwdriver tap the line lightly all the way from your connection on the frame back to the reservoir. Helps get the bubbles to rise up the line.
Sometimes a bit of air will get caught in the banjo fitting at the reservoir. After you think you have it all out, hold the brake lever in with a rubber band or strap and quickly loosen and then retighten the banjo. Any air trapped will be expelled and you should have a nice hard lever.

I have never in all my years depressed the lever and left it pressurized. A good flush is all I have ever needed to get a solid feel at the lever.

Thanks, I really appreciate this feedback. Sounds like a pretty straightforward process. I will report back with my results and hopefully help the next guy who may have similar questions.

Just want to clarify. So, fill the reservoir, pump/pull the lever, and this will help push the air back UP to the reservoir, thus getting the air out of the lines.

I'am also looking to do a complete brake system flush. So once this process is done, is it necessary to cap the reservoir, and depress the lever and leave the system pressurized for a period of time to help get the remaining air out of the system? Then proceed to bleed/flush the entire brake system with new fluid (also cycling the ABS system)?

Yes... keep doing this until it feels new again.. Once all is back to normal then you can proceed to a full flush on the brake and clutch ! (thumbs up)

Success! Thank you all so much for the extra bit of information here.
I used the 'burp' method described above with the clutch line. I did not remove the clutch lever, I just slowly was able to pump the lever as the air bubbles slowly worked their way back to the reservoir. Once the air bubbles stopped appearing, I then proceeded with flushing the clutch system with fresh fluid.

For the front breaks, I used the system of slowly opening the left side brake pads. I used a small piece of wood to carefully pry the pads apart, pushing the pistons into the calipers. Left side first, then the right side until the air bubbles stopped. I had my wife helping watch the fluid in the reservoir, and to tell me when the bubbles stopped being pushed up. I then flushed the system as you guys described, I got a few bubbles out on the right side caliper and none on the leftside. Brakes fee very solid right now.

Today I will cycle the ABS system with the plug under the seat, then re-bleed the front and rear brakes. Then if all looks good, I will double check the torque for each removed fastener, and take the Tenere out for a test ride.

Thanks guys for all the extra help, much appreciated.
