2012 terrastar brake problem

Could it be the ABS module? or the brake control module? How would i test that?

 

Would it be the ABS module or brake control module? How would you go about testing this?

 

No, lights come on when I push the pedal

 

The only warning light is the yellow triangle plus a “warn engine” text. But this Happens after I try to continue driving. My guess is that the engine is pulling too hard and this causing this light/warning.

shutting off the truck and restarting makes the warning and light go away, but the brakes are locked up. It’s only after 30-40 mins cool down that they release on their own.

It’s at my other mechanic, he is not sure what it is and doesn’t really want to continue replacing parts without more info. I called international dealer near me, they seem to think it’s the brake booster.

truck only has 100k miles. Pretty clean. Only other issue is the power windows and locks don’t work, but there was a couple service bulletin about that.

I brought the truck at an auction, truck was driven 60 miles to the auction location with no issue, sat for 3 weeks before the auction took place. I drove it off the lot and with my #### luck this happened before I made it home.

 

What do you think?

 

I dont believe the INTERNATIONAL MAXXFORCE 7 engines came with a hydro boost power steering unit. Its med duty truck.
