C220 w204 brake pipe.

[Bellow]

Thanks bellow.

A guy that owns his own garage doing mechanics as living, came down the other evening, he said he stays away from mercs & that he & another place said brake bleeding on them can be a nitemare.
1st ever for me.

I see a few using vacuum bleeding.

So got me thinking (a few minutes ago actually), if I put my pressure bleeder on resovour.. Then went to wheel 1, (using rag), open nipple, connect my syringe tool (as above), then pressure.up to 20psi on pump. Then went to my open nipple with syringe on & slowly sucked the fluid as well.

This could do it yes.?
Would act as vacuum.?

Thanks

I don't like the idea of vacuum bleeding because the seals in braking systems are designed to seal against pressure not vacuum. Sucking air in past them isn't conducive to the objective.
Bleeding can be downright awkward. My Chevy doesn't respond to pressure bleeding only the pedal method and if the rear line has been drained the open bleed valve and stroke pedal a few times method is required to get the fluid moving.
