|   need some avid mechanical setup advice | kokothemonkey
Mar 27, 2003 9:01 AM | | OK I am running 160 in the rear and 185 in the front with XTR levers. I have a problem in that my front brake feels awesome (very little reach to get the brake to engage) but my rear I cannot get as tight as my front. The rear brake takes a much greater lever pull to engage the brake, and if I adjust the barrel adjusters on the levers the brake rubs, and if I try to adjust the caliper knobs it also rubs. Do I need to loosen the set screws again and turn the inner (larger) knob in more? That is what I was going to try next. I know the rear will not feel quite as smooth as the front but I would like both levers to engage around the same pull distance.
Thanks a bunch,

| Cable routing | shiggy
Mar 27, 2003 9:22 AM | | The cable routing needs to be as strsaight as possible. Any bend causes extra friction and extra compression of the housing is needed when you pull the lever (the housing tries to straighten itself).
Also, many of us set our levers to engage very close to the bar. It may not feel "firm" or "solid" but the braking is still very powerfull.
BTW Use the barrel adjusters only to remove slack from the cable. Never for pad wear or other "feel" adjustments. The performance of the brake will suffer. |
| Hey koko, read the Avid instructions carefully (again) | OldSchool
Mar 27, 2003 10:13 AM | | Some of your questions/comments are addressed there. It seems that you don't quite "get" how the brakes are to be configured. It's really quite easy.
I just installed my first set a couple of months ago, and it was easier than installing V-brakes. You can have your levers engage the brake whereever you wish. The Avids are that adjustable...
Good luck,

| Re-install, re-align | uber-stupid
Mar 27, 2003 10:55 AM | | If decreasing the gap causes rub, then it's probly not aligned properly. Check the rotor first, to make sure it's perfectly true, which it should be, but have to make sure first.
Assuking the rotor's straight, loosen up the CPS bolts, tighten the knobs on the caliper again, like you should have done when you installed it, (and paying due attention to proportions on how the pads should be adjusted when you do this) until you can't rotate the wheel. Then re-tighten your CPS bolts, and adjust your pads. Pad proportion when alignign the caliper can be important, since you want to center the caliper such that the pads will be in their proper positions from the beginning.
The last poster was right... these things are designed to be very adjustable. Pay a lot of attention to the instructions though, because if you do it even a little bit wrong, it won't be properly aligned, and you'll have a hard time getting it to work properly without rubbing. |
