# When bleeding with a Mityvac...

Posted by RosenKen (93 SE 5spd) on July 13, 2003 at 17:08:23: After pumping up the vacuum and opening the bleeder, should I be seeing- 1) The vacuum staying relatively constant with a constant flow of brake fluid coming out the bleeder or: 2) The vacuum decreasing rapidly and not much fluid coming out. Thus I must repeat the process a few times to get the 2" of fluid the manual says to excavate. I'm guessing 1) is correct but both my rear wheels did a separate one. This is after I removed my caliper pistons to clean off the rust and replace the seals (that was pretty easy). I put on my braided steel brake lines too and now the pedal is mushier. I know how to bleed brakes with the 2-person method fine but i'm new to the Mityvac operation. Replys: Without a source of constant vacuum --> John vdP (93 SE) 19:36:50 7/13/2003 (0)
