Pads locking onto calipers - can this be disabled!
I've a '20 E53 and it's my first winter with the car. Been a great fall but things have gotten real with a week of snowfall.
My problem is the pads are stuck to the rotors after sitting for a bit. They're getting frozen/stuck on hard enough I'm having to put a fair bit of power in from the engine to break them loose. The noise of them breaking loose it quite something and it just seems completely unnecessary.
My question is, is there a setting or something that can stop all four wheels from locking down on vehicle shutdown? I mean, a park brake, fine. One wheel would be ok. To me this feels like something that will foul pads, rotors or both.

You could try disabling the parking brake (each time) by holding the parking brake or was it pulling while you simultaneously press the ignition button to turn off the vehicle, that will keep the parking brake from engaging but you need to do it everytime you turn off the vehicle.
As the parking brake auto engages when you turn off the engine or when you open the door after.

What I do is after starting my car, before I put it in reverse, is pull the brake release lever.
FYI and FWIW, at 40,000 miles I had to replace the rear pads and rotors which were heavily scored because of the rear brakes, which are electronic, did not always release. I now have nearly 50,000 miles and the front pads and rotors, which are original, are fine. The rear pads and rotors had to be replaced because the brakes often did not release, and I too had the same experience as you - horrible sound after sitting or in the rain and/or snow. That is why now, I always release the brakes before putting my car in gear.
Hope this helps.

BTW, when I spoke to my SA, he advised that the failure for the rear brakes to automatically unlock is a common problem.
Hope this clarifies.

After I posted and reading your post, I realized that almost 100% of the time, after parking, I put my car in reverse. 99% of the time when I put the car in reverse, the brakes automatically unlock. But the other 1%, it sometimes takes a lot of throttle to break the brakes free/lose. Not unlocking automatically is what caused my rear pads to prematurely wear and the rotors to be scored. Consequently, now I just use the break release lever after starting the car and before engaging the transmission.

- Check tire pressure
- In the winter turn on heated steering wheel and seats
- In drive selection, I put it in "individual mode" which for me is, engine: econo: suspension: comfort. steering: sport
- Release emergency brake
This is similar to what I have done for over 65 years of driving: previously all my cars had gauges for oil pressure and temp, water temp, battery charge, fuel: I routinely checked my gauges when starting and during driving as well. I was never a fan of "warning lights" instead of gauges. I like to know what is going on with my car. Like a pilot, I have a routine before I start driving and so far, it has served me well.

Do you mean by putting slight pressure on the brakes and moving back and forth? If so, no. But as I posted, when I mentioned the failure of the brakes to release after putting the car in gear, my SA said this was a common problem. So far by activating the brake release the problem has been solved.. Several things I do routinely when I start my car:

I guess if going electric then exhaust fume wouldn't had been an issue. However, that is not enough of a reason for me to go electric.

The vehicle has rear cross traffic alert right or was it only on the facelift. Obviously not something to over rely on but false positives are rare to none.

Moisture is the main issue why the brakes stick. Its flash rust building a perimeter around the brake pad and the caliper. Moisture is not something you can avoid. In the wet snowy winters here in the midwest, my rear brakes stick too. The other thing is to drive your car more. The more the brakes grind off the flash rust, the better. Not saying driving more will prevent the sticking brakes, but will knock off the prior remnants from the prior days.

Thanks mobster, when my day comes and the brakes need doing these will be gone and I'll move to aftermarket ceramics. If it was just an aesthetic issue I wouldn't care, its unbelievable how tightly they get stuck. Thankfully with colder weather the issue isn't occurring like it did during the first few warmer snowfalls.
Hopes this helps.
