Title: Hydraulic Banjo bolts
Post by: WetDuc on February 05, 2010, 03:40:55 AM
Is it necessary to bleed the brakes and clutch if you loosen the banjo bolt at the master cylinders to change the angle of the levers?  I haven't tried yet, but need to reposition them later.
Thanks.

I've had good luck holding pressure on the lever so just a little fluid escapes and no air enters. It's easier with a helper.

Otherwise you might need to bleed.

I'll try just loosening it a tiny bit first with some pressure on the lever.  My buddy will be there to help. 
I haven't ever bled the brakes before.  I have the workshop manual and have read up on the forum, so I know what to do.  The need just hasn't come up yet.  Is it worth it to get the vacuum or the pump kit? 

It's raining all day here today.

I've never found a need for a vacuum bleeder.

If you do end up bleeding just be careful you don't empty the reservoir. It's pretty small.

If you're just bleeding, a vac can be handy, but far from necessary. If you're doing more work, like flushing out all the fluid, or bleeding multiple bikes, then you might want one.

I did it once and my dealer does it "all the time". No issues. That doesn't mean it's foolproof though.
What I discovered is that the bolts are hard to move and once they move, they move more than needed. So, move the wrench with control - it takes very little bolt movement to adjust the banjo angle.

Thanks for the tip stopintime.   I saw a few previous posts on this topic you made in the past.  Fingers crossed, it will work well for us this afternoon.  I'll take some pictures of my buddy's 696 when we are done.

I did it when I lowered my headlight to rearrange the the erg's of my new clipons.  It worked, although I will likely bleed the clutch as the engagement position changed ever so slightly.
