Hi all...I want to flush the brake fluid on my 95 Maxima. The factory service manual outlines the two-person brake bleed method. Of course, when the brake is pumped and held down, opening the valve will cause the pedal to go all the way to the floorboard. I have done this procedure a few times in the past on this car but have always wondered if this is really OK for master cylinder components etc. After all, you are pushing it well past where it normally stops. I have also read some folks place a block of wood or similar material under the brake to limit travel but not sure if this is because they had the same concerns and is there really a difference between then going perhaps halfway between normal stop point and the floorboard?. I also saw several youtube videos about the one person bottle method but never really understood why the old fluid that is pushed into the bottle filled with clean fluid doesn't also suck the mixture back into the brake lines. Finally, I really don't do this often enough to buy a MityVac. I would assume the Nissan engineers have thought all about this before describing the two-person method in the manual but thought I would get some thoughts here too. My other thought was perhaps to open the bleeder valve just a bit and then close before the pedal hits the floorboard.
