Has anyone ever heard of this? The abs system slowly applying force to the brakes without me stepping on the pedal. I just get out and let the pressure off by opening one of the bleed valves on any wheel and this solves the problem for a little while, 10 miles or so depending on how much I use the brakes, yet It keeps coming back. Even happened going down the freeway without using the brakes at all. Recently changed a master cyl. and did get air into the system but I bled them and even fliped the front calipers in front to make sure there wasn't air in them. The abs light is on in the instr. cluster so I will have to have the dealer put the abs system in bleed mode but in the meantime if anyone has dealt with this or has any ideas what the #$%^ is going on give a shout.
