SID brake post threading

I want to install the V-brake posts on a '00 rockshox sid that, prior to this, solely used disc brakes. Dirt and grime has collected in the threads of the sockets and posts. I've heard that I can use a matching tap to clean out the threads, however I cant seem to find the specs on the threading pitch anywhere.

Can anyone help me with this? Or do any of you know a good alternate method of getting these nice and clean?

Thanks in advance,
Brian

My favorite way to clean tight little spaces on bikes or anything mechanical is with an air chuck.

The bolts that fasten the brakes to the bosses are M6 x 1mm.

This is a good example of why I always stick a well-greased bolt into any threaded hole, even if the bolt's not holding anything on.

It's not the bolts that fasten the brakes to the bosses; It's the brake bosses themselves which I need to install. They're removeable on SIDs, for weight/ asthetic reason I suppose.

I'm pretty sure the thread pitch is M8x1.25

If you're going to buy a tap, take the brake boss along with you to match up the threads.
