    I had this issue recently. My issue was I didn't push the rubber grommet all the way on the pipe so it just pushed it in the cylinder and not seal properly. Even though I "thought" the hose was clipped in tight but it wasn't and FAIL. Lesson learned.

    I know this thread is primarily concerning hydraulic lines leaking, but I'd like to offer a pro tip to prevent boot leaks for anyone doing clutch replacements or transmission/engine work that requires slave cylinders to be removed...

    The boot on the cylinder is compressed constantly while installed and subjected to heat over time. This makes the rubber conform and want to stay compressed. The longer you leave the cylinder removed, the more pressure you put on the boot because piston inside the slave cylinder is decompressing the boot. That's what causes it to come apart. So, either work quicker and get it back in place or use a c-clamp to keep it slightly compressed while it's off the car.

    It's been said many times to keep it compressed with a tie-wrap while it's off the car.
