Coming up to the first service B on my '17 cargo van with 17,870 miles. As part of this I'll be doing my first brake flush. The existing fluid looks great visually but I've always thought the pedal was a bit spongy so why not. Plan to try a Motive power bleeder for the first time and would like to know the best sequence rear to front on the bleeders and also the capacity of the system as in how much fluid to each wheel as the manual does not provide such info. I'm assuming Rt rear, Lft rear, Rt front Lft front. Thanks for the assist.
