Any mechanics/more knowledgeable drivers than my sorry ass have any idea what it could be?
I’m hoping it’s something I can do myself or get done over the road, because I have a whole other story last time this was in the shop and don’t want to deal with that again.
I’m in a 2022 International LT, brakes are sticking 90% of the time I use the pedal. Truck won’t move, brake lights stay on, air lets out painfully slow and I’m stuck anywhere from 3 to 10 seconds until the brake lights turn off and it rolls. Pulling one of the ABS fuses mostly fixes it. Brakes still won’t exhaust the air, but I don’t get stuck as bad. I also intermittently get a fault code for abs spn:1056 fmi:2. All I’ve been able to find online was a Mack throwing the code because the air lines at the trailer module were reversed.
I don’t believe it’s the pedal valve, that was checked before but could’ve been missed.
