I decided to change the brake pads myself. When I went to get the caliper off, the bolts were so corroded that theyre practically round. The sockets aren't gripping on to anything. I went at it with a monkey wrench too but cant get any grip anywhere. How am I going to get these things off?
If a monkey wrench wont do it, then those bolt outs are not even going to get close. Maybe you need a smaller pipe wrench? Can you fit it on there good? I've never seen a pipe wrench slip on anything if you load it up correctly. If it will fit on there, a pipe wrench is by far the best tool to use. Sure a welder will work, but if the bolt is that rusty you'd have to grind at it to clean it up, then lug out the welder.
Thanks for the input everyone but the bolt out sockets actually worked out great for me! I was surprised at such a simple concept. I found a set of 6 for only $19.99. I used the size smaller and fit it on nice and tight with a rubber hammer. Then I just had to turn it and break it free from the rust after soaking it in some more wd40. The bolt heads looked like they went through a garagedisposal afterwards, but thats nothing a trip to autozone couldn't fix.
Next time you need a liquid penetrant to get hardware loosened up from corrosion, use something like Liquid Wrench, Break-Free, or PB-Blaster. Using WD-40 for that job is like toasting your new bride or celebrating New Years with 7-Up. It may look like the same stuff but it's not and it doesn't work nearly as well.
the rotor would have to clear the wheel studs as well the the hub with the upper edge locked into the caliper. Rotor removal is impossible with the caliper still attached to the vehicle, if it wasn't you could replace rotors without removing the caliper. Not saying its absolutely impossible but you'd end up damaging a bunch of stuff to create the clearance to make it possible
