Question about brake bleeding

[nevets]

After replacing front wheel cylinders and flex hoses, will it be necessary to bleed the master cylinder?
Thanks!

Thanks Keoke, now one more wrinkle...I started to bleed the brakes using an EZ-Bleed pressurized bleeder, but when I got to the 3rd wheel (right front), I noticed that I unwittingly allowed the bleeder reservoir to go dry. Given these circumstances, do you think I will need to bleed the MC? What about the clutch slave cylinder?

I'll assume that your reply means - maybe

Yep.
However the clutch is aseparate system and should not have been affected.

Thanks Keoke, always good to get your input on these vexing problems.

When I recently installed my Toyota calipers with new hoses, found that gravity bleeding worked well. I'd pump the pedal a few times, then undo the bleeder screw slightly, letting the fluid flow until the bubbles quit. First bleed the driver's side, then the passenger side. The fluid flows from the reservoir through the master cylinder into the lines and through the hoses and calipers.

Steve G, When you did gravity bleeding, did you have a tube connected to the bleeder screw to a jar of brake fluid?

 

[steveg]

Yes. Open the bleeder screw until the fluid starts to flow, holding the screw against its seat to keep extra air from entering from the outside. Top up the reservoir as necessary. If your pedal is still spongy, repeat.

If you do gravity bleeding, how do you get to spend quality time with your spouse?

You mean you've never had your spouse as a helper to push the brake pedal down while pressure bleeding? "Push down." "Hold it" "Let it up" "Push down again" "Hold it" "No, that's the clutch pedal." Probably responsible for more divorces than any other auto repair.

OK, I get it. In my crowd we refer to the spouse as the "Dreaded Assistant". We will do almost anything to avoid invoking the Dreaded Assistant.
