DIY stuck brake lines, Help Please!
 

On a new 2014 sport with 300 miles adding Z1 SS lines but back stock wont free from block. All others on back will break loose. The small line that feeds into new brass block on Z1 lines. at point on rounding fitting with open end 10mm..

Any suggestions???

Try using some WD-40 and reposition the wrench or use vise-grips as a last resort





EDIT: There is NO reason for making multiple threads for the same thing.

One is enough just be patient. :ugh2:

NEVER use an open end wrench on a brake line! Go spend the $10 on a proper flare nut wrench.

I can't agree with this enough. Cheap at twice the price for the headaches it will save.

I agree with both the above, once you start to round it you might not even be able to get a line wrench on it anymore.

I prefer PB Blaster to WD.

You can also try some heat, but be careful... if you resort to ViceGrips you have already destroyed it and the line should be replaced. DO NOT get one of those line splicing kits with the union... it WILL fail.

If it's shot already then use whatever means to get it out and replace the entire line.
