OK, first let me say this is for a Kia Rondo 2009. I posted this on a Kia forum and no one responded. Problem; while driving on a highway at 55mph and not applying the brakes at all the car started braking on its own. I barely got to pull over before the brakes locked completely on ist own. Really bad smell of brake pads. Called a tow truck and waited about and hour. When tow truck arrived car drove fine, no brakes locked and I was able to drive it on a flat bed. So after cooling off brakes unlocked. I have not jacked car up to see which if not all calipers lock. So basically if car is driven for a while brake caliper/caliper seize. after cooling off caliper/calipers open??!
I never heard of this or seen it happen before. Anyone here ever experience this on any car. ABS problem? Caliper? Master?
