Posidrive size?

I am attempting to replace my rear brakes. There are two countersunk screws that hold the drums to the hubs. One of mine is very stuck. I think I will have to order a Posidrive screwdriver to get it out. Can anybody tell me what size Posidrive fits this screw?
Any other tips to remove this screw would be appreciated. (The other ones came out easily.)Thanks a lot.
 
Hi. I assume by posidrive you mean an inpact driver, that you hit with a hammer.

They come with a few different bits, but if the right size isn't with the kit you can pick up another bit at any hardware store, or most auto supply stores. Just make sure you set the tool for removal, not tighten. They can be a little confusing ( at least to me anyway..)

Good luck, mind you with this tool you should have no problem..

First, welcome to the forum. I'm not sure what size posidrive you;d need, but if you think you might ever have other damaged screws to deal with in your life, you might want to invest in a set of Sear's

Drill Out/Screw Out Power extractors They come in handy

Ken, the screws require a #3 Pozidrive bit. If you attempt to remove them with a regular Phillips, chances are you will strip the head of the screw.
The hammer operated impact driver will work, but you will have better luck using the proper tool.

When you replace the screws, put a bit of anti-sieze on them, and you won't have the problem again.

Welcome to the forum, as well!

Thanks for the help. The #3 bit did the trick. As the article explains, these things really grip.
I got a set of Posidrive bits #0, 1, 2 & 3 for 60 cents each from web page These are 1/4 inch hexagon bits that slip into the end of a screwdriver that accepts 1/4 inch interchangeable bits. If you don't already have one, Wiha has the bit holders starting at about six bucks.
