How do u bench bleed the master?

 

Hook a short piece of line to each port then work the master cylinder until you get a clear stream coming out of each end. You can loop the line so that it exits back into the master cylinder, kind of "recycling" the fluid. Usually you use a dowel or something similar to actuate the cylinder.

 

I took it in today...brake check couldn't figure it out at all...even hooked it to the computer to read the abs...nothing and now I have no brake at all...pedal goes ALL THE WAY! Booster was fine and no fluid was found so it's narrowed down to a clogged line and/or master cylinder like u said...

 

Clogged line? In that case the pedal should be as hard as a rock.

With no visible leaks, the only likely item is the master cylinder leaking internally.

 

Yeah, they didn't have right tool for this or that and wAnted me to pay for it...but pretty much back to master cylinder

 

well gotta thank u my friend... replaced the master cylinder and it works fine now...i took it by a 2nd shop too before hand and got a $1,500 estimate for some "contaminated" lines...dude wanted to replace master cylinder, wheel cylinders, brake calipers, brake lines, ****in everything... and all he did was come did some paper in the resivoir and say it was dirty lol what a joke...

 

Glad you got it fixed 01Kota. Thanks for posting back.

 

And bench bleeding was easy enough...took me not even an hr to pull old one and install new one man. Thanks
