Why your driver's side rear is bad...

[JDC802]

I created two pictures of my OEM Silverado brake pads. The GM electronic sensor only allows 2mm or .007" (Yes, .007" lol) of wear before it starts gouging your rotor. You can see a typical brake pad sensor on the same GM pad which allows 9mm or .347"

 

This is a design flaw and should be corrected by warranty! Not blaming it on the consumer because of the environment or your driving patterns. 

 

I WILL never put their junk defective and poorly designed sensor on any brake pad again. Would you?

Warranty doesn't correct design flaw.  That's engineering.

 

Many other brake pad wear sensors for other OEMs are designed similarly.  There is a bi-metallic strip imbedded in that plastic.  Once the air gap wears down enough, it will wear that strip down.  As it wears the strip, it will indicate the remaining life of the pads until worn (resistance value changes).

 

If you don't want the brake pad monitor working (which sounds like your main issue here), you can disable it and install the pads without the sensors.  

 

With how we see these at work, majority of rear brake issues on these new trucks is the pads get stuck in the bracket and things don't slide anymore.  

 

How to Disable the Brake Pad Life System

The brake pad life system can be turned off. This may be necessary if aftermarket brake pads without wear sensors are installed. 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. See Brakes.

To turn off the brake pad life system:

1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC).
2. Select DISABLE.

To turn the brake pad life system back on, follow the above steps but select ENABLE in Step 2.

Yep, I'm disabling it and not installing the electronic sensors.

The clip was still in place and in great shape with no rust yet. The only gouge in the rotor is where the sensor sits and wears down.

 

Anyway, my problem is now solved. Hopefully others can take this info and do as they see fit.

I think your calculator is broke.

 

 

Spent a lot of time over the years working in both inch and metric units (and frequently converting between them)and something didn't seem right -- so I pulled out the calculator. 

 

For exact conversion between inches and mm  1" = 25.4 mm  (inches x 25.4 = mm, mm / 25.4 = inches)

 

2 mm = 2/25.4 " = 0.0787"  ( not 0.007' )   

 

It might not be a huge amount, but about 80 thou of wear is a lot more than 7 thou...

 

Just saying...

 

Oh, and 9 / 25.4 = 0.0354mm, so that one one close

Exact thing just happened to my truck at 32000 miles and they said that a rock or an object must of got stuck in the pad causing the gouge in the rotor.  The message I got on my dash was not to replace pads...it says Service Brake Monitoring System.  Which to me means the monitor malfunctioned.  So now they want 700 to fix the back brakes.  Funny thing is that it showed 89% left right before the error showed up on my dash.

 

Could you please provide any more detail as to what was covered and what you replaced it with.  I am unsure what I should do next as I really don't think this is my fault and due to the brake monitor malfunction any damage should be covered under warranty.  Thanks.
