What order should I bleed the brakes on my TR6 with Mytivac? The manual says closest to the MC, but we all know that traditionally it's farthest from the MC first. My Mytivac doesn't seem to work well unless I'm doing something wrong. My pedal is firm at first then weak and pumping it firms it up but seconds later it goes limp. Suggestions? I can do it the old fashioned way, but then I have to ask my wife....
 
Save the frustration ask the Missis for a bit of help and do it the old fastioned way.---Keoke- /ubbthreads/images/graemlins/smile.gif
 
What Keoke said. Think of it as quality time!
I bought the same type tool and found it pretty much useless.

[/ QUOTE ]First, I'm with everyone else so far: toss the Myti-lack and do it the old-fashioned way. Second, where you start depends on what sort of brakes you have. According to Girling, all-drum or all-disc systems should be bled beginning from the rear, but disc front/drum rear setups should be bled beginning from the front. See this page from a January 1964 TSOA Newsletter: <https://www.templeoftriumph.org/tsoa/images/64jan4.jpg>.
 
My experience with it is that you can get it to work but you have to distinguish between when you're pulling fluid and bubbles of air through the system, and when you are done but just drawing air (bubbles) in around the bleed screw. The latter bubbles are much more evenly spaced and uniform and not an issue. I've done it in RR LR, RF, LF order. Think I've bled the clutch with it to. Close the bleedscrew while the Mityvac is sucking. (Obviously don't let the m.c. level drop too far also.)
 
If you put a hose from the bleeder nipple into a bucket of water (yup) and pump until no more bubbles come out you'll be set. Water will not come back into the system, and you only need to keep the master full.
[Yikes, here come the naysayers.]
