Is facing disc brake mounts on a new fork necessary?

myopic

Planning to fit Avid Elixirs to a prevously unused set of forks with post mount fittings. Park Tools website suggests facing of the mounts is necessary, but I've never heard of anyone getting this done. Is it necessary?

Nothing about it on the Avid fitting instructions.

nicklouse

nope.

there is not tool for Post mount.

Cheers, Nick! That was what I hoped. Should I lightly file/sand the paint off before mounting or just mount on top of it? I thought mounting without removing some might cause the paint to crack around the edges of the mount.

nicklouse

nothing needed.

Nick, is it worth doing on a new frame for the rear IS, & are all rear mounts IS?

Thanks

nicklouse

depends on the brakes.

generally yes. but Avids dont need it but it can help if there is too much crap on the mounts which can allow noise.

I'll running a Hope Tech V2 183mm on the rear of my P7 frame, so would you suggest I get it done?

Thanks again

There are a couple of makes that have post rear mounts but I think its harder to build post mount frames so for the foreseeable future its probably going to be expensive hand made frames only.
