Did you adjust the hex adjuster on the calipers? Unscrew the console nut all the way, take the cap bolt off the rear caliper. Use an allen key to turn the adjuster and turn the wheel as you adjust it. When it grabs, back off until its free again. Like half a turn. Once done on both sides you can go find a beastly hill and adjust the nut on the handle to desired tension.
Though. Ebrake is not affected by front brakes at all obv. Only needs adjustment when changing rear pads.
