Rear set question
« on: March 28, 2011, 05:57:15 PM »
I am finishing up my set up, used rear sets from a yamahaa fzr 600. I'm trying tO figure out my brake side now. it seems when I depress the pedal it's maxing out and turning over on the heim joint. I'm pretty sure moving the tab on the brake lever back would fix the issue but I kinda don't won't to start chopping up the lever. Wanted to see if anyone else had any ideas. Here's pix explaining. this pic shows where the brake is when it's not engaged

This shows what's happening

I would recommend shortening the length of the brake arm at the right. This will require more effort to actuate your brakes, but should stop the over-center situation.  You'll probably need to increase the length of your heim joint rod.
Just a thought you may want to consider  ;) ...never have rods like that go into compression when activating the brake since they're too easy to buckle and bend under hard braking.  Instead, try to have those kind of linkages stressed in the stretch direction.  If necessary, move both of the lever arms to the underside to avoid the compression of the thin rods.

Keeping the actuating rods on the bottom side of the pedal keeps things from going into compression, and instead are "pulled" and can't get bent.

The angles are wrong; you need to rotate the right lever clock-wise, which will require a longer rod. A line drawn though the pivot point and the rod ends of each lever should be roughly parallel. You may have to shorten the right arm as well?
As long as the rod is straight, and sturdy enough, there should be no problems with being under compression.   
Don't fix it if it ain't broke!

man i love this site, that #$%* didn't even cross my mind,  haha.  Awesome i will give it a try wenesday when i get some time.  And the linkage rod actually gets tubing around it so it doesn't buckle.  but now i think im going to run them on the underside anyway. thanks for the help.  Also any suggestions on where to get  foldable pegs from?  Im using the stock rear pegs right now.  But honestlly they feel a bit flimsy.
