I'm hoping someone can help me with this mystery. I cannot figure out what is causing my brakes to engage or rather not "disengage" after about 10-15 minutes of driving around. When the issue occurs, It starts off slowly with a slight sensation that the truck is suddenly pulling a heavy trailer, but then steadily becomes worse the further I go, eventually having to floor the gas to pull over safely off to the side. In the short term, If I pull over and pump the brake pedal a few times and start driving again it seems to fix the problem but only for a short while before it happens again. I have an OBD2 reader but it doesn't grant diagnostic data for brakes. I do have a live data read out of everything while the occurrence happens and would be glad to provide it if someone is able to use that info to narrow down a conclusion. When the issue happens, I can just let off the gas and the truck will come to a stop without needing to apply the brake. The feeling as if you're going through thick mud. I changed my brake pads about 3000 miles ago, so I don't see a correlation to my DIY brake job being the cause. The truck has 56K miles. Things that I've done so far: Replaced the Brake sensor control switch (code was thrown that mentioned Stabilitrak (it led me down a rabbit hole) (pain in the F'ng ass) - Still have issue. Took the calipers off and greased the pins. thought they might be getting stuck. - Issue is still present. Update: 01/20/2024 Replaced both front wheel hub assembly Added new brakes, Rotors, calipers Issue is still present. My next step would be to replace both the front calipers. <-- NOPE. I feel like I'm guessing at this point and the cause could be a Master Cylinder, Brake booster, Solenoid, bad brake fluid or lines. And to add, I have conspiracy monkeys in my head telling me it's all still related to the faulty GM vacuum pump issue. All this to say, if someone has dealt with a similar issue in the past and figured out the cause I would be grateful to hear from you.
