How can I connect both pressure sensors from my original Golf Mk4 master cylinder to the Porsche master cylinder if it only has one connection? Is there a way to continue using both sensors?
Use a T-piece:
You can install a T-piece with appropriate connectors to connect both pressure sensors into one line. This ensures both sensors receive the necessary pressure and your braking system remains functional.
