Rear Brakes not working properly on 2012 Expedition

[GlennSullivan]

No brake balance in the sense of a race car adjuster that can be adjusted with a wrench.

in modern vehicles brake pressure is automatically adjusted adjusted front / rear - left / right via the ABS module and wheel speed sensors.

All the brake lines go from the 2 circuits of the master cylinder to the ABS module and then to the individual wheels.

This is what I was thinking. I’m going to try and bleed the brakes tomorrow to see if that makes any difference. The pedal isn’t spongy at all and the pedal doesn’t go down o et time. The m thinking it’s a restriction somewhere in the system. I’ll post an update if I get a chance to work on it tomorrow.
