Yamaha parts

Yamaha no longer supplies the aluminum washers that fit on the banjo bolts for the brake lines.  Instead they have superceded it with a copper washer. This copper washer is much less thick than the original aluminum washer.   3 copper washers = 2 aluminum washers in thickness.
The problem I am having is on the front where we need 3 washers to seal the longer banjo bolt that goes into the caliper, the thickness difference is enough that the bolt bottoms out before it tightens up on the washers. It would take 5 copper washers  here to make up for the difference.  Instead of adding more washers/more surfaces to seal, I am thinking of just trimming the bolt length enough to make up for this. It looks like there is enough excess bolt there to do this. Any problems in doing this I cannot think of?

Spiegler supplies the thick aluminum crush washers with their brake lines. I went ahead a bought a bag from them. I use the double banjo at the master cylinder and run 2 lines down to the calipers. Less fittings that way and easier to bleed.

Got my aluminum brake line washers from Spiegler.  Only ~.65 cents each.  These 10mm washers have a torque spec. less than the one in my manual [84 1100]. The manual spec is 19 lbs but the spec for these washers is 14.7 [15] lbs. Also when I was putting them on, one can feel the washer crushing.  Feels like when one strips a bolt.  But with a torque wrench all is well.  I put copper washers on my slave cylinder and these aluminum washers feel much softer. Should provide a great seal.

Just remember to tighten till it strips, then back it off 1/2 a turn.....

Come on Monkey, stop giving out such crap advice.


Everyone knows you only back off 1/4 turn.  :-)
