Anecdotally, regenerative braking on an EV reduces brake pad wear by somewhere around 50-80%. It's rare to have to replace brake pads in an EV, or even to see them significantly worn.

On urban buses, which are constantly starting and stopping, I imagine it could be even more.

If EV companies were confident in their engineering, one could design a system with entirely electric braking.

No brake pads required. Simply dump the energy into the battery (or a big heater for the excess when the battery is full or too cold to charge)

Obviously, you can't have a failure in the electrical or control system or you can't brake anymore, so that part will have to be designed with much more redundancy than it is in todays vehicles.
