I took 2000 F250 7.3
in to replace broken brake line. Truck came back w/ ABS light on. Trucks runs/ stops fine. Sometimes the ABS light goes off. When it does, when i hit the brakes, the abs to work, like i'm sliding on ice. I don't know if its related, but my speedometer sometimes doesn't work either. And twice now the over drive light on the gear shift is wacky and doesn't light up properly. All these problems started after brakes went out due to brake line failure, and truck went to chevy dealer
. Any help would be great. THANKS SO MUCH.
