I have a 2020 GLE450 and I am at 66K miles and still on the original brakes. I don't understand how, but they have checked brake wear at each service and tell me I am good. I've never had this kind of brake life on my prior vehicles (a bunch of S5x0's and a CLS). I felt like I was lucky to get to 30 or 40K on those cars!

I think it is because of the mild hybrid and regen braking in the 450. If you are careful in how you brake and do it by anticipating the traffic ahead, and letting the regen kick in by a gentle dab on the brake, let the GLE slowdown and use the hard press of the brake only for the final stop, then you are minimizing the friction brakes a lot. I can see this clearly by the amount of brake dust on the freshly cleaned wheels of my GLE vs the dust on my Mazda, after a short grocery store trip for example. Mazda's brake dust is significantly higher compared to GLE's.

Lisle 24300 brake piston compressor tool. Works a treat.

I am not an expert but I normally change break pads and rotors myself. It is odd that a predominantly rear wheel drive vehicle has worn break pads on the front. If you are break pads have only 3 & 4 mm left than it is the right time to change it. As far as rotors, take a look at the rotor wear indicators (they are round indentations on your rotors). If they are fully gone then you need new rotors, or if your breaks are pulsating, then rotors might be warped.
New OEM GLE350 front break pads are $220, new OEM rotors are $165x2, break pad wear sensors are $17x2, and your dealer probably charges $250 in hour. So $1100 is not that inflated but $900 would be better, as long as you need to replace both break pads and rotors. Or you can go aftermarket parts that are much cheaper or change it at the independent MB shop.
Hope this helps, however as I mentioned it seems odd that you need front breaks on a rear wheel drive vehicle first. Your front tires also show unusual outer wear. It might suggest other issues, like tie rods or ball joints.
P.S. After looking into it further, it seams that front breaks will wear out faster on a rear wheel drive car due to front of the car caring more weight. Sorry for the confusion.

so, given that the fully bottomed out wear of these pads is 3mm, what is the typical thickness of new MB factory pads for the GLB 250?
thanks

I am always telling my wife the games dealer's play on brake wear... they tell you 7MM and you think it's tiny and have to change.

The front pads are still around 7 mm.

General specs for German cars is the wear sensor activates with 2mm pad thickness remaining. 2mm pad thickness gives several hundred miles of usage, or more, depending on driving style. The point is, when the wear sensor activates, there is time to replace pads.
Pad backing plate thickness is approx 6mm. Be careful when measuring brake pads - do not include backing plate thickness in the measurement.

if you a DIY guy you can save big money changing the pads and rotors you self. There pretty easy to do. Then again I just totaled the parts required and it's $747 bucks for 2 rotors and brake pads for the fronts. $400 bucks for someone else to change them see reasonable. I just like maintaining my Benz. I will take this one in for the A services though since they took away the dipsticks that we use to vacuum the old oil out.

Dealer wanted $900 including 2.5 hours of labor, which I think is unreasonable if you have a lift.
Parts for pads and rotors were around $200 plus $20 for Torx set. Took me 2 hours doing it in my driveway.

Yeah I have the sport brake package OEM on the fronts, so they cost a bit more. Frankly I surprised they don't include the rail slide and spring clips on that kit.

When replacing brake pads, do you replace the wear sensors too, and how many wear sensors do the front and rear consist of ?

There are two total wear sensors (1 front, 1 rear). If you haven't tripped them, they technically wouldn't need to be replaced. They are very cheap though, so I usually do them either way.

Or do they just put it on one tire?

One sensor per axle. They are on the inboard pad of the passenger side. In theory, if all is working properly brakes wear evenly enough that you only need it on a single pad. Real life doesn't always match theory....
