2003 dodge dakota, 2wd, 5 spd manual, v6. at speeds from 15 mph and up the brake system seems to fail as the truck jumps and skids very rapidly. the first time this happened i was on the freeway, traffic came to a halt quickly, i applied the brakes and almost lost control and hit the car in front of me as this jumping and skidding occured. all parts on the truck are factory and have not been modified. i am concerned and wondering if this has anything to do with the front suspension clunking. *tr
