Brake Pad Wear Sensors on ML
I have a question for all of you brake experts out there. How many brake pad wear sensors are there on a 2010 ML? If there are fewer than four, on which pads are they installed? Thanks much.

Usually it is installed on passenger side (on each wheel - in total: 2). In general, you can put on any side but when I have changed my pads, I found it there.

In general, once you are changing pads they are going be in good (working) condition but it is better to change it. If you go to local shop, they are going save it and reduce your bill for ~ 15 $ but I think it is always good to change it.

You are both right. Once the pad wears to let the sensor touch the disc, the sensor will wear.
However it is a spring so it does not get loaded up like the pads when you brake, so the sensor wear is absolutely minimal.

If you change the past before the light comes on the sensors could be used but generally they're brittle and will break in the process of trying to remove them from your pads.
I just installed new rear pads and they came with new sensors.

The brake pad wear sensors should only make contact and send the signal when the pad material left is very thin, about 10% I'd guess. Did u check the pads at all 4 wheels?

The calipers are not properly floating in their carriers. When brake is released the piston releases as it should but the entire caliper is cocked/wedged/stuck leaving the outer pad to drag on the disk.

I was thinking the opposite was happening when I replied earlier but no matter this is one of those situations where the answer is the same either way.
Inner pads are wearing because only the inner pad is being applied to the rotor. Any time inner or outer pads wear more than its mate the caliper is not properly floating.
As to whether its covered under warranty, it could go either way. If you are a regular customer of the service department then it should be covered because it is not the way one would like brake pads to wear. On the other hand it is an example of exactly why one inspects brakes periodically rather than wait on the brake pad sensor to speak.
As for brake pad sensors I'm a fan of GM's low tech solution of 30 or 40 years ago: a metal feeler which squeals when it contacts the rotor. Costs almost nothing. Dependable as a rock. Obnoxious enough to make careless drivers seek a remedy.

So I get to my neighborhood carcare center and ask them to replace the brake pads. They do what I told them to do, and they also returned the old pads. The fronts are indeed 50% left, and the rear about 35% left.
Fk the MB dealer. I am not going there except for oil changes.
Incidentally I think these brake sensors are the stupidest ideas ever to come out of German engineering. No wonder the Japanese never adopted it. The brake dust accumulates in the sensor slot making connections that should never have been and producing erroneous results.

that's very true, the inner pad always wears faster than outer, just looking at outer pad doesn't tell the complete story. On top of that, the sensor is always located on the inner pad. To truely tell how much meat is left, one has to take off the wheel and check the inner pad.
