Hello. First things first, this site has been extremely useful. Thanks to those who have helped me out. Learning about my vehicle has been easier than I would have thought.

Another question though. I am replacing the discs, pads and sensors on the front of my vehicle and have been having trouble getting the bolts that hold the caliper to the vehicle loose with my own strength. Searching the forum, I have seen a couple of ideas such as a cheater pipe or heating up the bolts. I have no idea if locktite has been used on the bolts and am wondering if anyone has conquered this problem. Will penetrating oil work? Do I need some air powered tools? The pads are out, caliper working fine but rotors are done. Any ideas are welcome.

Thanks.

Use an 18" breaker bar............they'll release.

A combination of penetrating oil, a breaker bar and 6-point socket should work fine. Per the book the caliper bolts should be replaced; however, I have always reused them without incident.

Why are you removing the caliper bolts?

Or is this a later model with floating calipers? In which case there is what, one per side? Does it take locktite?

Are there locking tabs on the mounting bolts?

No locking tabs. The OE bolts are coated with some type of plastic on the threads to prevent any possible rotation once installed.
