No, leave the engine off. The vacuum assist has nothing to do with the hydraulic fluid system. There is a certain order in which the bleeding should occur, starting at the ABS unit if I recall. Anyway, use the Search function and you will find a lot of info.
I just changed the entire brake fluid on my son's NA. Extremely simple. Very carefully suck out old fluid from master cylinder and SLOWLY top up with new. Bleed the brakes in the following order topping up master cylinder as you go. Front left, front right, left rear, right rear. Bleed each brake until fluid comes clear. You will freak at the colour of the old fluid. End result will be nice new brake fluid and all bleed perfectly. I did the clutch fluid at the same time. Same process. Bleed at the master cylinder first, then the nipple on the inner guard, then finally on the slave cylinder, making sure you top up as your going.
says in tech article left rear, right front, left front, right rear i thought it was always suppose to be to bleed the furthest one away from the master cylinder...ie left rear, right rear, left front, right front
