I am trying to put new front brakes on my 2007 CLS550. The caliper is held on by two torx E18 bolts. I have an E18 socket but I can't budge either bolt. These two bolts are located on the back side on the caliper. There are also two torx e18 bolts that are on the front side of the caliper adjacent to the rear bolts. Is it possible to loosen the caliper by loosening and removing the torx bolts on the front side of the caliper? Alternatively, does anyone have any ideas on how to get the rear frozen bolts out? I tried heating one. I also tried to get a bar on the end of my socket wrench to get some leverage but there is no room to do that. My air socket wrench did not have enough power to break the bolts loose. Does anyone have any ideas?
