A very good inexpensive vacuum bleeder. & as JohnW said sometimes the bleeder threads need sealing. JG.
Thankyou so much for that tip...is there a special tool used for the vacuum?
Hi John, what did you use for the vacuum?
I bought a proprietary brake bleeding suction kit. It is nice to have a vacuum gauge so you can see what is going on. It has a collection reservoir between the "gun" and the bleed nipple. Ebay or Supercheap, I can't recall which. Not expensive. I'll try and post a photo tomorrow. Mr A's tool looks good too!
Awsum, thankyou.
Whoops, forgot photo. I'll try again tomorrow! Sorry.
So sorry, forgot completely to photograph the self-bleeder. Just found a leaking calliper (overhauled in 2009) and remembered my promise...
You need to use heavy grease on the nipple threads and polish up the nipple itself, so you don't suck air right at the point of bleeding! Address those details, and it does work well.

$233 at Supercheap - "Not expensive" Not cheap either!
$233 and you don’t need a second person hating life...
“pump it up”
“hold”
“ok rest”
Have a brand new one available for $30 plus postage from 4226 .
I like my old mechanical fuel pump [shown earlier] & have never used the other.
Pumping is never a good practice, especially on a used system.
One can start with pump bleeding then end up having to overhaul the system because master cylinder seals are leaking after the pumping!
If it's never happened to you, you have been very lucky & smart mechanics don't take that re-do option, when working on customer's vehicles

Leaking rear calliper rebuilt, brakes rebled and the job represents no danger to marriage these days! Pedal not the best, so I'll rebleed at my leisure, early morning not late afternoon.....
Caravelle....if you're doing the whole show, it's best to flush through all the pipes
and clean all the seals and calipers with methylated spirits...blow dry with
compressed air and flush through the system with a high quality DOT-4 fluid.
Then refill with the DOT-4....DOT-5 is a veritable pain and in most instances not necessary.
That 'veritable pain' has never been observed in my experience of over 30 years of use & recommendation.
DOT 5 has real advantages over any hygroscopic [read all other glycol based brake fluids including DOT 5.1] especially on historic or classic vehicles that are not daily drivers.
DOT 5 is not corrosive & brake systems don't need internal attention [seized wheel cylinders, dragging brake shoes etc.] or to be flushed every couple of years.
There is the proviso that the system is clean of all other fluids & DOT 5 is not recommended with hydrovac or ABS systems as explained earlier.
I used to have veritable pain with hygroscopic brake fluids in cars used less regularly. IMHO it is especially an issue with the rear-engined Renaults with alloy disc callipers - pit corrosion behind the 'o' ring due to moisture absorbed exactly in that area. You do have to be careful to avoid aeration, which I suspect is why some folk believe Dot 5 is compressible.
Sorry to preach but some of us are converted.

I have one of these vacuum bleeders. Works OK, but I generally pressure bleed. I use it to empty the reservoir before putting in new fluid and pressure bleeding. $24 delivered

Thanks Alan,
How DO they do that for the money + profit??? For me, they work well if you seal up the nipple threads. When I think of bleeding debacles in early years when I really didn't know what I was doing (but thought I did....), I just shake my head.
What pressure do you apply when pressure bleeding?
Around 10 to 12 Psi. The plastic reservoirs seems to handle it OK. Even the glass ones are fine.
Thanks Alan.
