Have you tried turning off the Emergency Automatic Braking in the infotainment system? 

Yes.  I've tried turning off the grade braking, the stabilitrak, traction control, mashing the P-Brake.   None of these options have worked unfortunately

The picture attached isn't accurate to these trucks but what I'm getting at is the "poppet valve" in the image isn't fully closing or is leaking this would apply the brakes until the vacuum (on the va

No, I was replacing the original OEM pads as they were worn down. I cheaper out and bought the O'Reilly's brand BrakeBest pads. No problem with brakes sticking on original pads. However, first set of

Pumping the brakes momentarily relieves the problem?  When the problem begins does the truck pull to one side?  Have you felt the rims to see if one or more is hotter than the others?

Oddly enough, pulling over and pumping brakes and putting it reverse back into drive seems to temporarily get me back on the road.  After speaking with a mechanic friend he sends to think it might be wheel bearing issues.  

I just put it up on Jack stands and when I try spinning the front wheels, I don't get a full rotation freely after letting go.  

 

I don't have a lift or after market wheels.  I do have slight larger tires than factory (33x12.50 R20). I do tend drive in AWD from time to time.   So maybe the bearings are shot? I would've thought bad bearings would've thrown a code or something.

 

To answer your question, oddly enough, there is no pulling to either side.

 

If not the bearings... My new conspiracy might be the torque converter.  But again, that would most certainly throw a code or two given the outcome

Time to take the wheels off to check the brakes and wiggle the wheel hub. The way it sounds, you should be able to grab the top and bottom of the wheel and wiggle it. 

 

Yes it does sound like bearings. Or brake pads, clanking metal.

FWIW, I just had to have bearing replaced on passenger side. I had noticed my fuel economy had dropped off a bit. But what I really noticed was a noise on turning especially on sweepers. It wasnt a loud noise but a definite change. Driving straight forward was fine but when I turned left, the different noise was present. It went away as soon as I was driving forward again. This pointed to the right, passenger side wheel. Because of outside conditions and the fact that I'm a professional procrastinator, I let the dealer diagnose and they confirmed a bad wheel bearing in right side. I had it replaced and the sound went away. I also noticed that it held the line while driving ahead again as well. I had started getting a bit of sloppy wandering while driving straight ahead and I'm guessing that the additional resistance on the one side had a hand in that.

Just wanted to add that I also have a Goldwing trike. Last year, I diagnosed bad bearings on right rear side. Surprisingly, I didn't have any back and forth movement when grabbing the wheels but there was a bit of a grinding sound when manually spinning the wheel and it was more pronounced when compared to left side. I bought the replacement hubs from Rock Auto. The hubs were actually front wheel hubs for a 97 Cavalier. They appear to be similar to how the Silverado hubs look. It was stupid simple swapping out these trike hubs and for good measure, did both sides. 

 

I have seen several other threads on the Silverado front wheel bearings and they do seem to be an issue with failing...

The only reason I let the dealer do it was because it's still covered under the GM Protection Plan I purchased. Mine done last month was at just over 90k miles.

Rock on man. I use the truck to keep me busy outside. I'm always wrenching on something.

Well...

 

I'm officially tapping out!   I've replaced the brake pedal sensor switch, Both left and right Wheel hub assembly, rotors, pads, calipers, and complete flush.  Still have this damn issue.  

I just came across this post today and his scenario is damn near an exact as to what I'm  experiencing.

Check pedal to booster linkage.

 

If it were me I'd look at replacing the master cylinder or booster. 

 

Maybe just bleed the brakes for the experience?

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
