I had a line going from my secondary on my master cylinder to the distro/comb. valve rust out. It is now replaced but I don't want to bleed all my brakes when only half need it. If it was the line closer to the firewall then it should be for my front brakes correct?

Thanks

 

closest to the firewall is the rear, it is easy to bleed, just crack the bleeder and let gravity do the work, start with the furthest brake line first (pass side rear)

 

alright cool I'll give that a try Thanks

 

my original guess was correct. I gravity bled the rear brakes and it was not the correct half. This was on a 1983 Caprice with a 305 just for future reference.
