Master Cylinder Replacement Challenges, Reservoir Lines and Single Pole Contact Options

[DennisV]

I've run into a couple challenges while replacing our brake system.

The new master cylinder has a single pole contact, whereas the original had 2-pole. I read somewhere that you just leave one wire detached. Do you lose some functionality doing that?


I am having a hard time getting the plastic lines that run to the fluid reservoir to naturally land in a position where they would connect. The old lines appear to be identical to each other. Whereas the new lines are different from each other with different part numbers found in the factory parts catalog. Has anyone else run into this? These came from Porsche and I triple checked the numbers on the bag against the catalog. I inserted them into the master cylinder per the indication of the factory parts catalog. I have done all sorts of twisting and contorting but would have to bend one of them substantially to get them to align with the reservoir hoses.


Thank you.
