Did you need to wrap the bleeder threads in teflon tape to keep air from getting sucked in, or fluid leaking out, along the threads?
Larry, the bleeders came with some thick goop already applied to the threads. There is resistance when you put them in until they bottom, then you only open 1/4 turn when bleeding.
They worked fine for me. No leaks.
You will need to use Teflon tape after two or more bleedes.
I installed these years ago, and they work great with no leaks. However, using their # SB8125LL for the front caliper upper bleeders might provide more clearance/be above that nearby caliper bolt and allow a box wrench to be used instead of an open end wrench.
