Hi everyone, got a question about brake bleed on my ‘90 2.9L V6. Been tracing an issue with the rear brakes and have settled on the ABS Hydraulics Unit. I replaced the master so i know she’s good. The lines above Abs have solid flow and below ABS is zero flow so I know somethings up with the ABS unit. Does anyone know how to diagnose the module? I tried bleeding the brakes with 12V connected to see if it’ll open the valves, my guess is that they might be stuck closed? It’s an expensive module so I don’t want to replace it unless I have to, I’d rather troubleshoot it if possible. I’ve heard you might need some kind of special tool to diagnose.
