Bleeding (again)

I read through several pages of searches. Seems I've done what was suggested in most.
New system, front disc, rear drum, new MC, Prop valve and all new lines. Bench bled the MC and using a Mityvac on the rear wheels. So far the right rear is the only one to firm up and no more air. I've run almost a quart through just the rear brakes.
The bleeders all seemed a bit loose in the threads when cracked so I sealed just the threads with heavy grease, I could tell a difference but still sucking air on the left, some fluid but mainly air.
I got to thinking that maybe the seal in the left wheel cylinder isn't seated good and the vacuum is pulling air by it, no leak of fluid since none is in it.

Anyone ever run into that?

I'm thinking it's the L. rear W/C , there's not a kink in the line from the T fitting to the W/C correct. because the R side is OK, that only leaves those two items, line from T to W/C, or the W/C itself.
Good luck,

re: Bleeding (again)

When I use a Mityvac or any vacuum source I always pull the bleeders out and wrap the threads with Teflon tape ,the vacuum WILL pull air around the threads and you can not get a good bleed. Seal them and try again. Good Luck!!


Lost your job yet?
Keep buying foreign.
Oh and don't open the bleeders any more than you need to get flow,open too far and you will still get air.
