When I start the truck the ABS and the BRAKE light come on. It will stay on till I turn off the truck and restart it. If I turn on the truck and the lights are on, I can immediately restart it and it will be gone. Its interemitant. I had this once before when my power steering fluid was low. Its part of the hydroboost brake system. But all fluids check out. Any ideas? I already checked all the grounds. Seems to be electrical.
