brake pad surface not fully used

[RexFuzzle]

The vibration could be caused by that but once again I doubt it- I think it would still have to be "twisting" the disc a little but and with less in contact it might be able to do it a bit more.

I used Avid adapters with Shimano brakes, had all sorts of issues to get them spaced correctly, swapped out the adapters, all was good in the world. My advice, change the adapters.

This is the worst case I have ever seen of Brake surface OVERUSE!

Braking with the pistons, not even the pads!!

or, if the problem still persists, try the following

1. Remove caliper from adapter.
    
   
2. Remove lever fron bars.
    
   
3. Coil hose neatly
    
   
4. Pack away in spares box
    
   
5. Dig deep into pockets
    
   
6. Purchase Hope M4's
    
   
7. Fit
    
   
8. Forget.
   

 

ok, Peach and Super_mil would attest that I'm the last person to give advice on brake spacing. Heck, for months I ran a 160mm rotor on my Hope Mono Trial cos I was too lazy to put a 180mm on.

 

Then on another bike, I removed Avids to put Hope M4s on. Tired lazy me left those cup n cone spacers in. It took a few weeks to muster up the desire to change it.

 

That said... I run Avids on 2 of my bikes (Hopes on the other 2) and the Avids haven't given me any hassles... and if the brake is doing its job... I leave it... at leat until I can't stand my friends ragging me about my ghetto bike tech anymore

Crazy, I dont know how someone can not hear that ... probably cause it is Shimano quiet ... Avids you would have heard for sure!

So after checking this fred, i saw that my front brakes where set too high, they have the damn spacers in. Without the spacers, it uses the full brake pad. now the pad is half used, and has a duk groove in it. I will have to take it off and sand it down. Although i have just realized that i have taken off and worked on every single part of a bike, but never on the disk brakes caliper. Guess there is only one way to learn.

Sadly not at my tools will only be with them tomorrow to fix.
