So the only way to keep this system active is to buy OEM pads with the sensor?

Might be a nice feature to some but the metal wear tab was simple and worked.

There IS a sensor on these, it’s not just calculated by driving style. They use resistance wires built into pads that the truck reads. I have heard others saying the system doesn’t seem to be all that

Wow. A sensor? I stand corrected. That is crazy. Maybe that is why the calipers are bigger on the T1s? I am sure everything will be twice as expensive to replace. I would rather have adjustable

Just examine them like a normal human would and turn off that stupid function. I would think people do a proper inspection of their vehicle from time to time, rather than waiting for electronic system

97% front, 99% rear, after 3100 on the clock for me. The downshifting of the truck when coming to a stop, or after tapping the brakes when going down a hill, I would think save some wear.

As has been discussed most likely the dealer did not reset when the truck was new as they are supposed to.

And as others replied to you, their trucks were reading 100% when they picked it up from the dealer.

Sensors are in the pads, it’s not like the oil life or air filter monitor where it’s just computer calculated. There is an option to “reset” the system but it’s supposed to auto-detect the new pads and prompt the reset itself.

 

Seems like there’s two camps, people that have an accurate pad monitor and people that don’t. I’m thinking in these cases there something is out of calibration in the programming. Because usually both axles are dropping much faster than they should, thus theoretically ruling out a bad set of pads/ sensors unless they are bad on BOTH front and back. 

 

Seeing as how common this is becoming I would hope GM is aware.

 

I know the system can be disabled but it would be really annoying if the truck is repeatedly prompting for new brake pads at 10,000 miles and the only solution is turning it off.

Mine goes down 1% in the front for every 100 miles exactly. I just watched it on the odometer. 506 miles went to 95%, 606 miles went to 94%, 706 miles went to 93%. I drive mostly highway. At this rate my brakes will be "gone" at 10,006 miles. Hmm? Doesn't sound like a sensor to me

I only know that there is actually a sensor. What the truck does with that info is another thing completely.

 

Brake pad wear sensors are referenced both in the owner’s manual and a few times in the install manual for the performance brakes.

 

https://ecom-dam.ext.gm.com/parts/documents/ISheets_23505029.pdf

 

“The brake pad life system must be turned off. This is necessary because the Performance Brake Package is equipped with brake pads without electronic wear sensors. When the system is turned off, the front and rear brake pad life percentages will not display. However, the built-in wear indicators that make a high-pitched warning sound when the brake pads are worn can still determine when the pads should be replaced.”

Here’s a theory that may make sense. Since it appears that there is only a sensor in one pad up front, let’s take the cost cutting further and ask what if there is NO sensor for the rear pads, and it’s just calculated by how much the front is worn? Perhaps they figure the front wears out 2x faster or whatever the equation would be...

 

This would explain the entire reason to even have a manual reset. If you just change front pads then, the truck will continue to calculate the rear pad wear at the predetermined ratio. Same if you only change the rear pads. If it was 100% sensor driven as the owner’s manual would lead you to believe, there should be no need to even have a reset option.

 

If my BS speculation is true, you have only ONE sensor that is throwing the whole system off which seems more likely. If the front pads “appear” to be wearing faster than they are, due to an errant reading, then the rear percentage would also drop faster to match based on the system’s calculation.

 

Just a thought.

Last two trucks I have had I did multiple rear brake pad changes and never touched the fronts.

Isn't there an eboost software update that addresses this issue?  Seems like I read that somewhere..

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
