ok i have an 85 with rear calipers...one is frozen so im replacing both the thing is i cant get the line out of the old caliper...a 16mm line wrench doesnt fit but a 17mm does but there is some space, i have already starting to round off one of the bolts using the line wrench and stopped to make this post.

ive used parts cleaner and have removed oll of the **** from around the line bolt so its not that that is getting in the way of the 16mm

 

use a 16 open end, bump the wrench with the palm of your hand.

 

ive tried that but yea i just called our main RX guy here in town and he says its not a 16mm it should b a 17mm

 

You do NOT want to use an open end wrench with brake lines, you are for sure going to round them off. One you get them loosened, then you can then use an open end to speed up the process. Spray some penetrating oil on them and let them sit, PB Buster works wonders. Let that stuff sit for a while and let it "work." It's either one or the other, i know it's metric. Your last resort would be to use a pair of vise-grips and maybe replace the hose if you mangle the hell out of it, but it might not be a bad idea on a 20yr old car.

 

i had to heat my calipers with a cutting torch, but i wasnt reusing them so it didnt matter if i fried the seals in them....

that cutting torch was so instrumental in getting my rear end swap done.

 

Everytime I use a Line wrench I round off the fittings. I just use and open end and bump the wrench, If you use an open end and try to just pull then it will round.

Palm of your hand and bump the wrench and they will come loose.

 

Use a line wrench, and bump it.. Its ALOT better then using a open end, which only rounds them off easliy.

 

Just me but if your having that much trouble with the old lines I'm guessing they are the original lines. If so it wouldnt be a bad idea to replace those too. So if you have the $$$ buy some new lines (only good can come from new lines anyways). stainless would be pretty. and just cut the old ones and use a box end or visegrips to get those old bums out. That's what I did when I replaced the hard lines.

 

yea if its rounding off its junk, just cut them and buy new

 

If you're going to cut them you could then use a six-point box end wrench.

 

I took the calipers off and put them in a vice, then put a 17mm open wrench on the line and tapped it with a hammer until it budged. Of course I'm getting SS hoses so it was okay to cut it first

 

yea fvck it i just cut it and ordered new braided line
