About this deal
All well and good. But Fiat have used an aluminium case with stainless steel spring fingers inside to retain the fitting. The aluminium corrodes against the stainless and the considerable expansion of aluminium oxide = a ruined fitting that will never separate. Even if it does come apart, the components are scrapped by corrosion damage.
OUR CUSTOMERS HAVE DISCOVERED BY TRIAL & ERROR, THAT THESE UNIONS ARE COMPATIBLE WITH SOME VARIANTS OF:VAUXHALL/OPEL
Lightly abrade the cut ends of the remaining installed pipes to remove any burr taking care not to let any debris enter the pipe. I did this, and worked first time for me. I have attached a diagram of the clutch pipe for reference. You do really need to pump the pedal between opening the bleed valve, and not just let gravity do its thing as haynes suggests, as this will purge the air out. Solution is replace master and slave together as you'll get a new fitting. Use copper grease on the fitting to coat the stainless spring fingers and it might come apart next time, but don't hold your breath.
Step 8: Get a syringe and fill with clean brake fluid, slide under the van and push this fluid into the slave cylinder connector pipe. It is a bit messy, but more you get in there the better.seal the clutch reservoir with a plastic bag over the threaded top and screw the lid down tight. to reduce the risk of fluid dripping once you have cut the pipes.. see following. Bleed the system by attaching a tube to the bleed nipple located on the slave cylinder which is accessible now that the battery tray has been removed. I wont go into the bleeding process because there are number is slightly different methods. Just remember to remove the plastic bag off the reservoir lid before starting.
