1995 Winnebago Adventurer 30WQ w/P30 Chevy Chasis/454 engine: Auto brake can activate without warning while driving. Did Chevy ever do a redesign to fix this? Can I have my mechanic bypass the actuator and put a "Parking Brake Toggle Switch" in the cab? I want to be proactive and fix this before I have the brake activate at highway speeds as has happened to others.
