As I remember, the 01' has an Allen pin (I might be wrong) and it is often rounded out by using an old Allen wrench

that has worn flutes (aluminum drain plugs are notorious for this) so you might want to get a new set or cut off about 5mm

from your wrenches. If it's an Allen pin (5mm, I think?) you might try taking the pads out and using some penetrating oil on it,

than use a Torx bit a little larger than the rounded out hole, tap it in and use a wrench to back it out. Be absolutely sure to put

some anti-seize on the new pin threads.

If it, in fact, is a hex head nut, penetrating oil (take the pads out to not get oil on them) and a slot cut on the head with an

abrasive disk in a Dremel tool will allow a slotted screwdriver to back it out.

ps. I thought I'd add a little more to the post. The Torx bits are easy to carry in the tool chest and work pretty well on Allen's that are stripped out (dress those Allen wrenches, you'll have a lot less heads stripped out). The Torx bit is tapped in and can be rapped a couple of times to help"shock" the capscrew and loosen the bond somewhat. A short 1/4" socket and wrench can be used to put pressure on the bit when extracting the capscrew.

A T-15 works well on 3mm heads, a T-45 on 6mm aluminum drainplugs etc. In a pinch you can also re-install the bolt or plug using the Torx bit untill you get a replacement.
