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

mlipmd · 07-02-2023

OK, so finally with a friend going in under the car from the front and me on the side and him pulling on the slave and me pulling on the 13mm flare wrench with another wrench as an extender on it for more leverage, I finally broke that hydraulic line fitting free from the slave. And amazing how clean it was, no dirt or rust, all threads looking brand new. Dirty little fcker for giving me so much trouble.
So now I have another problem needing help or enlightenment as to tricks for getting the slave back in.
I prefilled it with DOT4 and bleed it on the bench doing that, connected the old hydraulic line as it was dripping fluid slowly so minimizing air and bleeding of the system, but now the big problem is getting it back in place and bolting it on. I know you have to center the rod in the depression in the fork but how do you apply enough pressure to compress the slave against the spring inside and get it in place? There's either some trick to this or I am missing something basic.
I really don't want to empty the slave to try and make it easier to compress the cylinder in the slave, was wondering about applying suction at the master possibly making it easier to compress the slave.
I need ideas on how to get the slave back in.
