I replaced my steel brakelines in doing so the system ran dry. After bleeding them when I come to a stop and the last foot or two before stopping my pedel will drop 3/4 to the floor and than will continue brakeing.I had to unplug my abs power and they now work fine but without ABS.

those old abs units are a real biotch to bleed...some special tools/procedures needed

yes theyre very air sensitive. need to make sure youre bleeding them with the proportioning valve open
