I live in SF, and often park on sloped driveway/streets.
The car use to roll a lot before it settle on the parking brake pads as described in this post.

Last summer it was time for all around brake job (rotors + pads + sensors)
I adjusted parking brakes using the above TIS procedure.
It has been 9 month, 5K miles - almost no roll at all.

It is easier to do the adjustment with wheel off, but wheel on works too
