Gee, it appears that the bolts holding the non-moving part of the caliper is not removable. It should be, but I was unable to move the bolts AT ALL. I gave up after tapping the wrench (socket and box) with a 3lb sledge, but both wrenches kept caming off.
Uhm…. Yeah. I guess I’m keeping the same rotors.
The sledge will just frustrate you, and possibly hurt you or the car. What you need is a torque extension. This is what I had to do with the Jeep (often), which has everything welded together with rust. I used the handle to the floor jack as an extension on the end of my ratchet, to give me much more torque. Just extending the length of your wrench a couple of feet will make it MUCH easier to get the bolt off, additionally, a breaker bar can be had from any tools type place for about $10.00 It’s basiclly a ratchet without the ratcheting part. They are much strong than a ratchet and will allow you to put much mroe force on a bolt than a socket/ratchet set would on it’s own.
Finally some good penetrating oil sprayed on the bolt and left to sit for as long as you can will also help the process along.
If all the above fails, impact wrenches, torches or TNT will usually get things apart. The further down that list the more exciting :)
HTH!
