I was fortunate enough to get the master cylinder, prop valve, front brakes, and rearend off of a true 1le to put on my rs. ive already swapped the master cylinder and prop valve while all the brakes are disconnected. my question is, since ive already flushed the fluid with the new master and prop valve, do i still need to bleed the master cylinder, or would flushing the fluid out of the bare hardlines mean i only need to bleed the brakes when theyre installed.

 

check out this thread. some one else asked the same thing. hopefully this will help ya.

you'll need to bleed the entire system anytime the master cylinder is replaced.

 

what i meant was this: the car has no brakes or suspension on it at the moment. the only things on it are the master cylinder, prop valve, and the brake hardlines. the front calipers are off and the rear end is out. i flushed fresh brake fluid through the hardlines to get the old stuff out. i got all kinds of air bubbles up through the master, so i wanted to know if all i need to do now is bleed the brakes once they are installed, or do i still need to flush the master even though there are no longer any air bubbles coming up through it.

 

its super easy to bleed the master cylinder. If it were me, I would go ahead and bleed the entire system just to be on the safe side.
