I have no idea what just happened. I was driving the XB and all of of sudden it just stopped dead in its tracks. The engine was still running and rev'd up just fine, but the wheels locked up and would not go. Upon closer inspection, it appears that the brakes have locked up, although i'm not 100% sure. I just know that the lever that the brake servo linkage runs through absolutely will not move. Its stuck and refuses to let go. It seems as though once I get one thing fixed, something else goes wrong or breaks! I appreciate any kind of help I can get with this particular issue as I am really not sure what to do about it. Thanks!
