Brake differential valve issues
94 F250 IDI Turbo
replaced brake lines, brake hoses, pads, drivers caliper and rotor.
Truck pulls to the left when braking and the drivers side gets significantly hotter than the passenger side.
I have the red brake light on.
i was reading the Haynes maintenance book and says how to reset the valve to get the light off, but will that valve also change the pressure to equalize the pressure? Or is that valve on to trip the light?

it works, pistons move freely, and it does get warm, but the drivers side gets hot. I am wondering if the New caliper is bad out of the box? But that seems extremely unlikely

The Red brake light indicates the parking brake may not be fully seated in the Off position. Low brake fluid or the low vacuum switch (diesel only) can also trigger the Red brake lamp but also usually triggers the Yellow ABS lamp as well.

The passenger side caliper is seized or seizing up, and your driver side is doing all the work.
You should do brakes in pairs.
