Brake Pad Monitor

[Padraig]

I had this posted in the wrong section so repeating it here.

I have a 2023 Suburban Duramax. On the info page is a brake life monitor. Does anyone know how it measures brake life? Also, how accurate is it?

Thanks.

Here's a closer look at how the pad life is measured.

That system is very similar to what BMW has used for years.
The pad thickness sensor is also a wear item and must be replaced when you change your brake pads.

Thanks everyone! That is what I was looking for, the mechanics of it. I wonder if non dealers can replace the sensor

As long as they can source the parts it shouldn't be difficult to replace the wear sensor.
The big question is if you need a Tech 2 to reset the display, if it resets automatically with a new sensor, you can reset it like you would your tripometer, or an advanced ODB II tool would be needed.

See excerpt in post 2, system is supposed to reset; and it does imply the sensor needs replacement.

Easy peasy - plug and play. There's one sensor per axle (driver side) so it's $28 added to a brake job to replace the sensors...

No Tech 2 is going to work on this gen for a brake pad monitor.

gds2, tech2 only works up to 2013/2014
