Hello. does your excursion have hydro boost? what engine is in it?
Did you bench bleed the master cylinder before installing it? If you believe that your abs hydraulic control unit has air in it, it will need to be bled using a scan tool with automated brake bleeding capability for your truck. The scan tool will walk you through it. We use a modis, but there are qute a few that will do it. If you'd like, I can email you the bleeding procedure for your truck.
Ok. When you installed the new master cylinder, if you didn't bench bleed it, you probably do have air in your hydraulic control unit and will need an automated bleed. The automated bleed procedure is part of the program in your scan tool if it's supported. you would select your vehicle, and select automated bleed and it would instruct you to open a particular bleeder screw, then press the button, etc. If your not seeing automated abs bleed in your scan tool, then it's likely not supported. It has to be a bi directional scan tool in order to do it. they are pretty expensive. ours was 10k
although im sure there are less expensive ones out there
I will open the question up then in the event that someone here has the command for your scan tool. I would think the command would already be programmed in your scan tool.
Different tech here, do you still need help?
