We discussed this some years back on the old forum, but I feel it merits re-stating. I do not recall if it was ever discussed here.

If you plan to own the coach long enough to ever bleed the brakes again, you yourself two big favors:

1 - Pull the bleed screws out and clean the threads, then put a turn and an half of teflon tape on them.

2 - Buy and use the rubber caps.

This really helps if you like anyplace that has water around at all. Brake fluid is highly hydroscopic. It can use that moisture to corrode the threads. With the teflon on there, it can't get into the threads. The cap just keeps any extra water from getting in there.

I started doing this several decades back after having to replace wheel parts on funny furrin cars because bleed screws could not be moved without breaking. I started by using teflon pipe thread sealant, and while it was better than nothing, it had to be replaced with every bleed. Then Chuck Boyd said he used teflon tape. I changed and still do.

This also helps if you vacuum bleed. I vacuum bleed because funny furrin cars can't take a clamp plate on the plastic reservoir.
