frozen brake line fittings

[John Axtell]

I know this is probably a no-brainer for those who have a bit of experiance. Anyway, I am currently replacing the rear drum brakes on my 2000 Ranger.
The fittings into the wheel cylinders were frozen but as I was replacing everything I just twisted them off. Now however I have come to where the two lines meet at the little ( brass ? ) junction on top of the pumpkin.
I have soaked them for two days with PB Blaster and still they won't release!
I started with proper wrench then worked my way to vise grips. By now the everything has become a bit rounded. I really don't want to replace the junction fitting as I think I then might be into ABS problems.
Any advice would be very welcome
Thanks in advance..

cut the hard lines and get them out of the way. if things arent rounded too bad you may be able to pound a socket on it and take em loose that way or if not try a craftsman bolt extractor set. they look like sockets but have 'teeth' inside that will grip rounded fasteners. other than that a good set of vice grips, crank em down really tight. may want to try a little heat but dont damage your soft lines.

that junction on top of the diff. is just a "T"...theres nothing special about it and it doesnt effect abs...so you can replace it with another from just about any parts store.

Thanks for the reply. Yeah I thought about that but it would just lead me further up the line to the next frozen fitting. Sort of "the buck (literally) stops here" sort of deal

If all the fitings are that bad, you might as well just go and repalce all the lines. I just had the same thing with my 98 this winter, except I had other problems...which led to a complete replacement of my brake system (except for the abs unit...master, booster, all calipers, whole rear brake system, parking brake, everything)

Hey, at least I can stop now.

I know I should, and probably will replace all lines, in the spring. Financially unable to do it now. When I started I was just replacing drums and shoes. Then decided to go with new wheel cylinders. After that I found my parking brakes were totally f***ed. If it wasn't for NYS inspection I would probably go without a parking brake as I never use it anyway.
Right now I need to get it back on the road and the weather is closing in on my garage under the stars (and rain, snow etc.)
So I would like to end it here at the junction.
Thanks for all who answered and anyone else who might have suggestions
