I need to change the front pads on my 98 Xantia 1.8 8v According to the manual I just pull the split pin out of the lower retaining pin, extract the pin and then rotate the caliper about it's top mounting bolt. My problem is even after the split pins are removed I cannot get either retaining pin to budge, they are seized solid. Does anyone have any idea how I can get these out? I have already tried soaking them with WD40 and that did not do the trick. I don't care about destroying the pins because I have a new mounting set so new pins to go in their place.
