    Maybe time for a new slack adjuster. You have one over-adjusting by the sound of it. Have a mechanic that knows what they’re doing check the pushrod length and angles of the slack adjusters first. There are a couple of details in there that can cause over adjustment, but if that’s all good you just need a slack. I’ve had some come back that had maxi chambers changed at shops on the road that were all ####ed up. Cut the pushrod too long and it adjusts almost every time you make a brake application.
