Only the drivers side activates? Not both?

I don't understand the reluctance to use it. I have it in Auto and never worry. In the winter, when it is very cold and snowing, I turn ot off to avoid the brakes freezing overnight. Probably just being ****, but other than that I never give it a thought. On when I park off when I move.

Only the driver's side has the electric parking brake. Lots of information and video links on this page:

The wear and tear from using it multiple times a day and it just serves no purpose unless you're parked on a steep hill.

The steering wheel also moves when parking, and locking the car moves the mirrors. Lots of motors to go bad, but short of disconnecting the car from itself, I say enjoy the features.

The brake hardware was made for multi-uses. And for vehicle/passenger safety, it does serve a purpose as I outlined above. Yes, someday it might wear out. If it does - fix it. I didn't buy a Lexus expecting that I shouldn't use a (safety) feature because it might wear out, or that it might not be cheap to repair.

Yep but those serve some purpose (TO ME). I also disable the easy exit seat movement. Don't need it so why cause unneeded wear. I like coffee ice cream - you may like vanilla

I think there are two actuators, one for each side of the rear wheels (left and right). I remember changing out o-rings for both when I changed rear pads.

I'm of the same mindset - I use the feature and never think about it. Living in a hilly area, making frequent use of a parking brake was habit learned a long time ago. I also really dislike the grinding thunk you hear when taking a vehicle out of Park when it's been hanging on the pawl due to an incline.

It's a great feature IMO, I had a '68 Cadillac which had an automatica parking brake release when put into Reverse or Drive, I missed that feature in subsequent cars till it was re-introduced in current cars.

I'm pretty sure both rear calipers have electric parking brakes. Just check your ready calipers. If they have the plastic black piece then they have the electric motor.
