Bleed tool.

This kit does not work in standard form..rubbish. I have had to improve it, now works in a conventional way ie open,pump, close, open, pump etc.

 

whats that in the jug? looks like the stuff left over from a turkey roast

 

I put some Water in first, why waste brake fluid. Clever or what.

 

ahh never realised it went cloudy

 

yes bought one. it was rubbish! I ended up using the old spanner.

One prob with vacuum style bleeders is that there is a chance that air gets sucked in through the nipple which you loosen once you let the pedal go.
I guess the ones working on the pressurising principle avoid this

 

Very true.

 

I've had one of these for years, they do work but not as well as they make it look. I've been looking around for something better as they're not that great.

The best tip I can give is to remove the bleed valves (good excuse to replace the shit metal bleed valves for stainless ones) and use some white PTFE tape around the threads of the valves and re-fit them; then only slacken the valve off about 1/3rd of a turn, maybe even less, then use as intended.

If you slacken it off anymore (especially without the PTFE) I find that it leaks air past the threads as you pump the lever/pedal. With the PTFE sealing the threads it works way better.

 

A good idea .

 

Latest version. Now air tight with "pump".

 

Oh, by the way it works. Brilliant. Best the rear brake has been, better than what the dealer did.

 

great guy - love your handy work on plastic bottles

mike-- I read about ptfe tape to seal the bleeding valve. I guess you have to remove it once the job is finished (because of the caliper getting hot). Is that so?

considered getting the mitac but wasn't convinced about suckinh air through the bleed nipple- I'll wait to see what mike's thoughts are

 

No you just leave it there, otherwise you'd have to bleed your brakes again wouldn't you?

 

thanks pal,
I take it you had no issues with the tape either melting or burning off once the caliper heats up.

I was thinking more in terms if you removed the tape once the job is finished and before tightening the bleed nipple

 

I purchased a used Mittyvac 8550 from fleabay , not used it yet but after viewing the youtube videos on it i think it may be ok.

 

Im still tempted to buy some stahlbus speed beer valves, they are pricey bit they look good.
anyone got any btw!

 

I finally bought the 8000 vaccum tool.

Must say I find it fiddley specially the long curly hose going to the nipple is a little too rigid, wobbles a lot and want to come off. Silicon hose would have been much better.

Sure enough there was a lot of air being sucked through the nipple thread so I did the PTFE tape trick (also mentioned in the handbook) which reduced it a lot but still some bubbles getting through.

For a first timer like myself, the trick is not to be put off by it as long as the level in the reservoir goes down, it means it is extracting fuild.

Must say the front & rear brakes feel much former. The rear is really powerful now.

 

Had one of these for years, great when you put new hoses on and you have to evacuate huge amounts of air, but IMO a PITA for normal bleeding.

 

I put silicon tubing from my aquarium on the mityvac. I replace it each time I use it because I heard the brake fluid can disintegrate silicon tubing. Not sure that is true, but to be safe, I just replace it.
