avid brake question

[Dennis]

hey, I haven't posted in a while, been working on the old car and getting it back in shape, a bit rusty.

anyway, as its snowing heavily outside today, my mind started wandering about bikes. I would like to polish and then anodize a pair of avid discs for Blue Crush to replace the v-brakes. (maybe)

I remember someone posted pics of polished avids a while back that looked awesome. in order to do this, I think it would be best to take the brakes apart (it would be necessary for anodization).

Has anyone tried to do this? there are torx screws on them, but they have a "pin" or something sticking up in the middle to prevent them from being loosened. I wonder if Avid would take them apart for and then put them back together after anodizing.

any body have any ideas about this?

thanks

I remember that pic you were talking about. They came out nice!

I've been working on a weight weenie project with my old set of BB7's (first set I bought used which look like crap). I've taken those two screws out (M5 x 25mm long, for reference) and replaced them with ti bolts. Saves 5 grams per caliper.

The two halves of the caliper are bonded I THINK, then the screws are used as further support.

I just took a dremel tool, removed the centers of the original tamper-safe torx bolts, then took a "normal" torx bit and took them out. Easy.

DON'T take the two halves apart. Just remove the bolts, take them to your anodizer, tell them not to drop them and when you get them back put the bolts in and ride your new bling.

I fear that if the halves are taken apart they will never work the same. Has to do with bad ju-ju, or karma you know.

There are special Torx screwdrivers which have a hole in the middle to fit for those special torx screws. I have such screwdrivers.
So this should be no prob.

But.
If you take the brakes apart you will hyve to change all seals afterwards. Including the piston seals.
So be sure you can get a o-ring and seal set from avid in advance. Otherwise I wouldn't do it.

A pretty nice idea anyway.
Let us see the results.

oh, I didn't realize they had "tamper resistant" torx screws. how tamper resistant can they be if you can go down to Sears and get drivers for them?

any way, thanks for the replies. I am going to email Avid and see if they will take apart my brakes, send them to me, then put them back together after I get them anodized. I just want to be safe.

Those kind of screws are called "Resistorx".

What do you mean "take them apart"? If you mean to take the guts out of them you can do that yourself with an Avid MDT-1 tool. The resistorx bolts don't have anything to do with the innards.

Here's a link to their pdf file.

This is all you need to do to remove the mechanical's inside. You can do this yourself. The tool will cost less then all the shipping you'd have to pay.

I am an idiot. I should have realized that there were instructions on how to disassemble and reassemble these brakes.

how stupid of me.

thank you for coming to my aid.

Hey now - no name calling allowed, even if it's yourself.

You should be able to get that tool at/ordered from your LBS. That, or if you ask them REALLY nice you may even be able to get them to do it for you ..... IF they have that tool in stock (if they don't then run away!).
