So just got home from picking up my truck... I gave them the TSB and they said i had the correct pads on. They kept telling me the squeaking and humming is normal and they can't do anything because 1. I'm over the 7500 miles to do the TSB and 2. I have the correct pads... The supervisor said he has a 2500 that does the same and he just lives with it..... i have never had a vehicle that does this and it be normal.... I even showed the service advisor my video and she said that is pretty loud.. UGH...


Does it go away after the brakes warm up?

Found it, a little google always helps. Thanks all. When I called to ask them if it was covered under warranty she said bring it in and lets see. I mentioned I found the TSB on it, so it should be cov

there is a TSB for this issue. Apparently the early build trucks have an improper spec'd pad. they replace pads at all 4 wheels

No. It’s intermittent also. It happens the most when coming to a stop at low speeds <10mph and it always happens in a drive thru.

I picked my truck up this afternoon.

I have a copy of the TSB that I will upload tomorrow with pictures of the pads.

So far no squeaking...

As per KuiMonster’s post, my problems were intermittent but they never made noise when I was stopping from a speed more than 35 miles an hour or if I applied the brakes firmly.

They replaced my truck’s brakes because since we bought it in Sept 2019 (It’s a 2020 2500HD), it has squealed coming to stops. Well now it sounds like a DUMP TRUCK when coming to a stop. I took it back in and they said sorry, no fix no change so just live with it now.

The new pads are not squeaking for me.

I have put about 600 miles on them so far.

A lot of the miles have been towing and I apply more pressure to stop (the noise seemed to be worse with slow easy stops for me).

Where's the copy of the TSB? I'm sure plenty of us here could use that info.

Less than 3000 miles on the truck, and mine are getting noisy now.  Build date on my truck is 8/2020 though.  Wonder if the tsb has been extended for newer builds?  Also now have a faint whine sound that sounds like a power steering issue.

I’m at ~18,000 miles - anybody know if they limit the miles for the TSB?

It’s 7,500 miles the dealer told me. But if my pads were the wrong ones they would change it even tho I had 9,500 miles. Good luck. My dealer sucks. 2* for a reason.

Hi,

I looked up my invoice.

The new pad part numbers are:

84702753 (S) Pad Kit
84571661 (S) Pad Kit

I have a long gravel driveway and my brakes will still squeal for the first stop or two but it’s much better than previously.

It sounds as though every dealer is "handling" this differently.  Mine tried to say a TSB doesn't mean that it's covered, only that they are going to get bum-rushed with the issue.  I called BS on that!  The next excuse was the wear parts only carry a 12 month/12,000 mile warranty and if it's not a recall, the warranty language kicks in.  I just decided to pull the "loyalty" card on them and mention the 3 GMC Sierras, and 2 Cadillacs that we have purchased there and that I will just take my business elsewhere from here on out.  Long-story-short, the service manager "pulled some strings" with the factory and they covered it.  I have new pads on all four corners, rotors where not glazed, and only time will tell.

Had the pads replaced per the TSB this morning - DRW with 8,100 miles, but I reported the issue a few weeks back. My dealer service adviser team is great, though, and they always take care of me.

 

Question: My break pad monitor now just shows "----" for the front, and still at 96% for the rear.  I tried to reset in the DIC, but it would not do anything. I only have 15 miles on them from dealer to home.  Will this correct itself with some miles, or did they not do something right? Per the manual and the DIC, it has a menu where you can tell it "replaced front pads" and/or "replaced rear pads." Mine doesn't do anything when I press the thumb wheel.

check to see if they plugged the sensor back in. It is only on the driver side

My truck makes a squecking noise when driving - not even when applying the brakes.  I tried for months to pinpoint where it is coming from but I cannot tell when in truck.  Could it be this issue?  It drives me freaking crazy.

Nailed it. Plug was on, but not snapped all the way. Oddly, the truck still will not let me reset the sensors in the DIC - still at 96% as they were when I brought it in. Not a big deal, but annoying nonetheless.

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
