My front calipers are siezing up. It started with the pass. side about a week ago now the drivers side is doing it also. And the ABS light is on thru all this. I don't know much about ABS units but I was wondering if this may be the original culprit of the problem. I haven't pulled a caliper off to see if the piston retracts easily while disconnected from the car, if it does then I will have to think that the problem lies somewhere else (ABS or master cyl). But I was just wondering if anyone else had a similar problem, since I won't get a shot at doing this until the weekend.
