When slowing down, I have to pump brakes to not have it feel like running over a corrugated roadway with no braking action (seems like I'll go right into the next car or obstacle) so I lift foot off pedal & try again. They now are working. A car buff said it sounds like the ABS system is not working & don't put any more money into car. So I bought a used car, but have to sell this one and want to let buyer know what is problem.
