This morning I decided it would be a good idea to change the brake fuild in my truck. When I went to loosen the brake bleeder screws I found them to be extremely tight. Though they didn't appear to be very rusty I soaked them for hours in penetrating oil. Using a tight fitting open end wrentch the only result was slipping around the corners of the nut. A good pair of vicegrips tighten as tight as I thought I dare tighten them resulted in only a slip as well. These must have been installed by the same factory Gonzilla that put on my original oil filter! Does anyone have a good solution to this problem? Thanks in advance!
