What tool do you need to remove the two bolts that hold the caliper to the spindle?
On GM model cars I know you use a Torx socket. You can purchase them at Checker Auto Parts.
On my 2004 c1500 Chevy 2wd the torx socket size is 55. But they are frozen. i could not even get them loose with an air impact. I guess I will try heating it with a torch and hope I don't fry the brake caliper seal.
They are held in place on GM and Oldsmobile with a Torx T-55 bolt. The bolt is held in place with the red colored Loctite, so it will take a good deal of force to remove it, or gentle tapping combined with heat. (A 4' breaker bar worked on my 92 olds.)
