I drive from my wheelchair. Im buying a new GM vehicle. Do you know if the 2015 (and 2016) Buick Enclave, Chevy Tahoe and GMC Yukon - come with electric or hydraulic powered brakes?
In order to make the braking easier (and backup system) the handicap conversion places prefer hydraulic. Otherwise I have to spend even more money to have them change electric brakes to hydraulic. Thx!
Here is a cool video showing how i drive from my wheelchair...

The 2015 should have hydraulics. Here'* a link for 2015 - no info on the 2016, but it'* a fair bet they will also be hydraulic.

The main braking system is hydraulic. The only thing that'* even close to the electrical part is the Abs system.

Pretty cool video.
