2012 terrastar brake problem

They have a Hydro-Vac brake Booster, the international dealer seems to think this was the issue. So might be the next thing i replace. However is there a way to test it?

First thing is the check what the engine is logging for codes. I don't think it logs codes for being worked too hard. There are codes for the brake pedal being held down too long. If the truck sat for a long time before you bought it, it is possible you just have seized calipers. You already replaced the fronts, if your rears are smoking, I would replace those too.

 

I have a 2016 doing the same thing. What was your repair to fix it? I was thinking about putting a hydro boost on it. Already did the calipers and break lines. Sounds like we had the same trouble

 

I’ve seen a few of these rust up badly between the master cylinder and hydro boost, causing the brakes to stick slightly.

 

Did you ever figure out what was causing the brake problem?

 

Did you find the problem yet??

Thanks,
Michael
