In a prior thread I posted the problem where I'm getting brake dust on the left front and literally nothing on the right. New calipers, rotors, pads, and lines and the problem continues. The right front wheel spins freely while the left front seems to grab a bit but still turns. The suggestion was possible air in the lines still, probably ABS, but I would need the Tech I or equal to do the auto bleed.
Well I found someone with the computer and sure enough there's an auto bleed feature. On the rear calipers the pump was noticeable and fluid poured out of the calipers but on the fronts only a few drops of fluid. While doing this it takes you step by step through the process and the question IS:
Does this help anyone diagnose the problem or is that normal that a lot of fluid flushes from the rear and little or none from the front?
Does this indicate there's a valve problem in the ABS?
All of the valves seemed to pump or at least make the noise while there's a noticeable difference in the rear v. the front.
There were no errors or DICs on the computer while the system performed the auto flush. The guys that had the tool were stumped as they've never used that feature.....long story. Anyways, now I'm bleeding each caliper and I notice the fluid is just nasty so clearly the ABS auto bleed must have cleared out something. I flushed by brakes twice before until they were clear so now I'm repeating the process and I've already gone through a quart of fluid on the front two calipers.
