I pulled the speed sensor off the hub and got the rust off and that did nothing. With the speed sensor pulled off the hub and just hanging free the problem seems to become less frequent ( every 20 seconds ) as opposed to every 5-10 seconds but still present. I also replaced the proportioning valve a second time to eliminate that as the cause.
have the same problem?
