Check adjustment, check for a leaking wheel cylinder, check for axle seal leaks.

No leaks, only way to unlock it was to back off the adjuster but it keeps adjusting to lock up when I drive.

Is it adjusting till it locks? Are all springs on the adjuster?

I had changed out a leaking cylinder and bled the brakes like normal. This was a month ago. After reading a manual on bleeding it after I change a wheel cylinder it told me I need to bleed the abs also. It has the ehcu 4-wheel abs system. Now what do I do?
