Hey guys. This question is a bit odd. I just got a shimano slx brake (front) and it wont quite hit the rotor all the way (the pad). There is about 1/2 to 3/4mm of space between the lower part of the rotor and the bottom of the pad. Im using an avid adapter through post mounts to a manitou post mount fork. Its also slightly slanted on the adapter and not flush to the place where it bolts in (the caliper) due to the design and since I didnt use cps bolts (didnt fit). A mechanic I took it to said its fine but Im a perfectionist. It does work yes, but whats the best approach to this. Should I even concern myself with it?

is the pad making contact on all the surface?

You say it misses at the bottom, but if the whole pad makes contact with the rotor, then there is not much more you can get, you would just be shifting where the pads sit on the rotor.

Not completely. About 1/2 to 1/3mm of the pad is riding above the top of thd rotor. Its not a huge amount but im not sure if it has any significant effect in the end...

You are worried about 0.33-0.5mm? Really?

Closer to .5 to .75. I just want as much power as I can get. More importantly the caliper mounts are not flush with the adapter...that worries me more.

The rotor/bracket fit is a much bigger issue. Fix that and I bet the rotor "fit" will improve.

Meant caliper/bracket fit
Ya thats what gets me confused. If I put any spacers in to make it fit as it should, it pushes the pads even farther from the rotor. Its on an angle due to lack of spacers. I think that maybe the avid adapters just dont work with shimano stuff?

Are you using the Avid CPS washer stack with the Shimano caliper? If so, GET RID OF THEM!

Cool. I guess I should just ignore the lack of flushness between the adapter and caliper? It is minmal after all. Thanks alot!

I do not see it in the pics, but if it bothers you, file the bracket.

So wait. How could shimano realize I havent been using their recommended hardware? Am I not risking damage to the caliper mounting plates using an off camber adapter?

Yes. I solved the problem. Had to file both sides of the adapter on a file till they could accept the caliper flat and flush to the facing rather than angled off.
