ZR-1 Net Registry Forums - View Single Post - Removing tight hydraulic line from slave cylinder

mlipmd · 07-01-2023

I have soaked that fitting with PBBlaster for a week and it hasn't done a thing. I used the best penetrating liquid ever, which has always worked when everything else has failed - a mix of ATF and acetone, and that hasn't worked so far either. I got my metric flare wrenches (my fitting is 13mm) and I can't budge it at all, it's like it's welded together (and after 28-33 years, it probably is). Next thing is to heat it up with a torch and see if a friend of mine who maybe is stronger than me can come for a try. Too bad Ahnold isn't around. And I know, righty tighty, lefty loosey so don't start with that.
If all fails, I guess I have to order a new hydraulic line and take the front of the car apart to change it out. I wasn't really wanting to do that but I may have no choice.
Anyone have a recommendation for a hose line covered in SS braid or should I go with a factory replica with SS tubing and rubber hose in the middle?
