Removing a rotor with a stripped retaining bolt?

Hey all, I was doing a brake change including rotors on the rear of my car the other day, and the rotor retaining bolt for my second rotor stripped out. I can't use an allen key to remove it anymore... should I just drill out the head of the bolt, and pull the rotor over the stub, then work on the rest of it afterward? I have ordered some new bolts to replace all of them, but how do I deal with this one?

any help would be appreciated!!

Thanks!

Well you can do one of two things..I have done both and they both work. First you can get an easy out, i dont know if thats the right technical term, but u drill a hole first then use the easy out to extract the bolt. The second way would be to get a dremel or get a grinder attachment for your drill and create a slot for a straighthead screw driver. I usually prefer htis method becuase its easiest. Good Luck

^^^True. The technical term for an "easy out" is an Extractor. Your local NAPA store usually carries sets of four. I believe you would need a Number 3 Extractor for this job. It is Time consuming, but if you have to time and the tools, go for it. I don't like the slotting method, b/c it is too easy to strip out the slot you just made. With the extractor, use a 5/32 drill bit to create a pilot hole for it, then tap it lightly until it seats into place. Trustme, when you cant turn it by hand, it should be good enough to grab the bolt. Then just turn it with a pair of Vise Grips, and back it out.

Two wheels or Four, I'm happy as long as the throttle is pinned.

Thanks guys! I appreciate the ideas, I will probably try the slotting method first because it costs me... TIME! Easy Out's cost... MONEY! LOL
I will keep up to date as time allows!

And DAVE, GET YOUR ASS DOWN HERE!!!!!
ARGH!
