I intend to bench bleed master cyl What is the best way to bleed all of this now ?...I am thinking of attaching a mity vac to each wheel cyl and pulling in the fluid,to each wheel then doing the conventional bleed with a helper ( my wife) to complete the process... Is there a better/easier way...TIA..I don't want to spend hours pumping brake pedal, listening to wife complain.... | | | | | Joined: Oct 2005 Posts: 4,249 "Hey! I sound like Darth Vader!! | | "Hey!

Then use the Mighty Vac to bleed the wheels. Just draw down the fluid until you see no more air bubbles being drawn out.
I'm assuming the master is low ( under the cab ) on the truck. If it is up high ( on the firewall ) that makes life even easier. Remove the cover on the master, open a bleeder and let it gravity bleed!
On all systems, I'll either tap the wheel cylinder or caliper to knock loose any air bubbles, then crack the bleeders one last time. On a new system, after I think I have most of it bled, I will pump the pedal a few times, go back to each wheel cylinder / caliper and recrack the bleeder to let the final trapped air out. | | | | | Joined: Jun 2012 Posts: 69 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2012 Posts: 69 | My concern is all of the system is new, wheel cyl, lines, hoses...there'll be a bunch of air to expel...The master cyl is mounted on the frame below drivers feet..56 3100 truck..Just lookin' for the quickest/easiest way.. | | | | | Joined: Oct 2005 Posts: 4,249 "Hey!

Once you have fluid at a wheel cylinder, a majority of the air is gone. Check your reservor often. The Mighty Vac should work fine. | | |
