OK So heres my problem.

I'm replacing the master cylinder in my 94 Prelude. I have rounded off the 12mm nut on the MC.

I am useing a 12mm brake line spanner also. I have tried use vice grips but that didn't work.

Dose anyone have any ideas on how I can get this off within dammaging the fluid line? I really dont want to weld a spanner on there because I dont know how to replace the whole line.

PLEASE HELP!!

Thnaks ppl

 

you can cut it off, put a new nut on, and reflare the line.

 

man, same thing happened to me a couple nights ago when i was replacing my cmc. I rounded the 12mm a bit using a wrench and vise grips but in the end i ended up spraying WD40 and letting it soak in for a while....then tried the vise grips again (clamp it really tight.....use slip joint pliers to close the vise if possiable) and it broke free. What makes it worse is, the space is tight...Good luck!
