Sounds like yours is messed up bad. Unless you know how to deal with those kinds of problems I would strongly suggest going to a certified brake expert and get it done right. I changed my own brakes most of my life but when there are ABS problems I won't touch them. Awards

Make sure you check the Diff. fluid i would change it if ithas not been done . If it has limited slip you should add the additive to too. At the town garage where i work we change the trucks between 50 to 75 thousand miles. Cheap insurance. Awards

You should bleed your brakes while you are at it.Air on the line can cause you alot of trouble with anti-lock brakes. Awards
