damned right!!! fear of not using the full cylinder stroke in case of

Yes, there are several 90-degree nipples, but none that fit
the rears. I am using one of the cone-shaped ones, and it's
a poor fit into the bleeder bolt.

I like the HD/Lowes idea. I'll go looking for a good fit
soon and use some of the adapters to go from small tube
diameter to the larger diameter hose that came with the
Mity-Vac kit.

To the others: I want to stick with the Mity-Vac approach a
bit longer.

who knows? the small tube might "interference fit" inside the mityvac
tubing.

i like my mityvac. unscrew the bleeder, pump it a couple times, eye on
the brake fluid reservoir. once it starts coming out "straw colored", im
done.

It sure seemed easy this second time around. Though I have a
new floor jack and now four jack stands, and that helped.

About how much brake fluid do you tend to end up using on a
flush?

Hi Elle. No answers, but a few ? Where is a good source to
buy the Mity-Vac?

I'm getting ready to do a flush. Any trouble getting the
bleeders off? I don't know when mine were last touched,
& hope they don't cause trouble.

I plan on using Motul Dot 5.1 fluid. Anyone have any

The Mity-Vac (metal pump) kit I bought for around $40 is the
following:
http://www.harborfreight.com/cpi/cta...temnumber=2068

It's on sale for about $40 now. Take a printout of the site
above with you to the store to get the sale price.

Harbor Freight also sells a plastic pump version for around
$32. It is probably just fine.

From googling more on this, a lot of people have had "one
person brake bleed/flush" success with "Speed Bleeder
valves." One removes the old bleeder bolts and installs
these in their place. See site www.speedbleeder.com . Pep
Boys sells these one way (= check) valves, too.

No, though if it's been awhile, I'd spray down the threads
as best I could with the penetrating oil "PB Blaster"
(around $4 for a big spray can). Great stuff.

I think I have read of people overtorquing and so breaking
these tiny bolts, though. Only 7 ft-lbs. is specified in the
manual for my 91 Civic.

Isn't that silicone brake fluid (to be distinguished from
the "synthetic" DOT 3 and 4 brake fluids)? It doesn't mix
with the DOT 3 and 4, as I understand it. I don't think
there's much reason to use other than DOT 3 and 4. Googling
for {"Brake fluid" silicone "DOT 3"} etc. turns up a lot.
E.g. see http://www.afcoracing.com/tech_pages/fluid.shtml

Let the group know how it goes... :-) I found it a little
tricky the first time but the second time was a breeze, like
I said, though I hope to improve on the rear brakes' bleed
part.
