Bleeding a dry brake system
This past weekend while I was painting calipers and installing new brake pads instead of plugging the brake lines after I disconnected them I let them all run dry. Even though I never touched the brake peddle the master cylinder ran completely dry.
After putting everything back together I bled the brakes for a day and a half and still wasn't getting all of the air out of the system. I finally threw in the towel and brought it to a mechanic. He had worked on a Honda with ABS on it before and had the same problem of not being able to get all of the air out of the lines. What he eventually found out was that there was air trapped in the ABS module, and he needed to hook it up to a computer to get the ABS to activate and push the air and fluid out.
He checked with Isuzu, and apparenlty the way to bleed a completely dry VehiCross brake system is to remove the fuse for the ABS and do a standard bleed with the motor running.
I don't know what this does, but it works like a charm as now the brakes are bled and working great.
