    Often the ABS sensors at the wheels get contaminated with metallic dust from the brakes and cause intermittent failures like you describe. I've been able to clean them with a blast of compressed air, wearing appropriate eye and face protection. It doesn't always work, but it's worth a try. Or bring it to a mechanic who works on Traction and ABS systems.
