Disc tab facing tools

For all of you who have installed disc brakes...did you bother to have the fork/frame tabs faced so that they are perpendicular to the axle vector? Be honest, did most of you just install them and everything was okay? I am all for doing things right but I really didn't want to spend the money on this tool and I am not going to bring it to a bike shop because I like to do my own work and learn as I go.

What are your opinions? I hear that this can alleviate squeal as well...

thanks

I've never bothered with it. Then again I use Avids and their CPS system makes installation super easy. It's a nice thing but not critical

Hey thanks for a quick response. I have seen one made by hope for about $115... I am pretty meticulous in how I do things so I am thinking that as long as I shim it good and the forks/frame are not too out of whack from the factory than I should be fine. I did not think it was something many riders did...so now I feel a little better, thanks.

Raiyn, you never jumped in on my pad prep liquid question from last week?

Sounds good to me, and anymore tolerances are pretty decent from the factory.

I wasn't here the latter part of last week so I may have missed the question

here it is...what do you think?

(while you were gone)
I was just wondering if it is okay to use the commercially available prep compounds that you apply to the back of brake pads for automobiles for MTB disc applications??? I am not sure whether it would really help or not, but it shouldn't hurt anything...right?

Totally unnecessary. All it would potentially due is get places where it would do more harm than good.

Why are you dissapointed? I just saved you a lot of extra effort and potential clean up

hahahh I am just giving you grief. I thought that I might have had a good idea but I know you are most likely right. We're not talking a car here.

I have read many of your posts and value your opinions...so please chime in whenever you have time for one of my future questions.

I have had to face the disc tabs on about five bikes, two of which used Avid mechanicals. The only time it is really necessary is if you are getting brake pad rub on the pad closest to the frame. If you are getting rub on the pad closest to the wheel then you can generally just use spacers (washers).

I have only had to do one or two of them to eliminate squeeling. Most disc mounts come pretty straight from the manufacturer.

When facing I always use the Magura. It's not cheap though.

I was checking out the Hope one though, it says that it fits into the rear dropouts. Will it not do the fork also? http://www.speedgoat.com/product.asp...=330&brand=110

The hope tool has a two axles, one for the rear and one for the front. Since the part of the axel where the plate with holes clamps to is 20mm it will also work with 20mm forks.

Thanks...I've been checking that one out. Mostly because of the price and also because I bought Hope brakes. I might as well wait until all my new parts are assembled and see how it all fits together. I am getting the stripped down version of the Rock Shox Reba model and have a Homegrown frame which I guess was made in the Yeti factory years ago. Anyway, hopefully the tolerances will all be pretty good.

However, I am a specialty tool geek. I like buying stuff like that. Wouldn't be surprised if I end up with a Hope facing tool...but I'll try not to.
