In the winter when there was lots of snow it would throw both an ABS light and brake light and it would go away when dry. It went away as soon as it got warmer but the the last few days of rain it tends to pull real hard to the right and takes dang near forever to stop.

I had the brakes checked a month ago after it had an issue in the rain and the mechanic could find nothing, all rotors and pads in good condition.

What would make the van want to pull right and take a long time to stop but only in really wet conditions. It hasn't thrown a light in the rains yet.
