Just curious, does consistent use of HOLD cause (much) faster brake wear?

I cannot imagine that it does, since it isn’t experiencing friction from forward movement.

I reserve the right to be wrong…

Correct, no friction thus little if no wear is really happening.

Agreed. The caliper/pad function is not affected. The only thing different is the action causing the caliper/pad function - the computer instead of your foot. So, unless your practice is to put the car in park when you would otherwise use hold, I can't see it increasing wear. On the contrary, if you are sitting with your foot on the brake, you are more likely to roll and stop and roll and stop.

What I thought, but wanted to check to be sure. Thanks as always

Hold surely uses the park / emergency brake? Separate to the discs/caliper?

My understanding is hold just electronically applies the brake to keep the car from rolling forward at idle speed. It's just your foot on the brake, waiting for the light to turn green and the cars to move. But in this case, it's an imaginary foot. It's one of the coolest little features, and I had no idea it existed until it was shown to me at delivery.

Exactly.

There's "Hill Assist" which is an anti-stall feature when the car is on an incline and trying to engage 1st gear, and "Hold" (or Hill Hold), which prevents creep when stopped at a red light.

I used to have that on my 68 Roadrunner's Hurst shifter to prevent rolls at the Xmas tree.... Sure wish I could have my T-handle back...

The brakes only wear when they are applied while the car is moving…
