brake caliper mounting bolts

[danfman]

I've had my Saturn about a year and haven't had to do any work on it, I guess that is a good thing. I was trying to change the brake pads last night but the caliper mounting bolts wouldn't budge. I've never seen bolts on that tight. I am assuming there is probably loc-tite or similar on them since they've never been removed before. I've worked on brakes before but have never seen anything like this. It looks like too tight of a spot to get a torque wrench back there. right now it's soaking in PB Blaster, but I have rarely had success with that. Anyone seen anything like this or have any suggestions?

I changed my SW1 pads over the winter holidays. I didn't have a problem, but I remember them being tight. I did them cold, after sitting a night. I may have had to put a long "breaker bar" type wrench on them. You know, one of those 2' long arms for the socket. Another tip I heard is to just break them loose by tightening a notch, then back them out.
Also, MAKE SURE you pump up the fluid to the slaves again. I thought I had, but had an unpleasant surprise on the 1st drive.
good luck

torque wrenches are used for seting finial torque after tightening, not for breaking loose sezied bolt. doing such will damage the wench and throw off calibation.

i suggest the following
1. breaker bar
2. breaker bar with cheater bar
3. heat(propane)
4. air tools

I had the same problem on my '98 SL. The caliper bolt rusted, and froze itself inside the caliper. My neighbor used an impact gun to free it.

Good luck.
