Am I an idiot!

Instructions in Mandarin, Grasshopper?

Do you get any drippage without the thing attached? Get flow going then hook up the one-way valve.

Could be you have a "schmootz" blockage at the screw, jab the pedal to see if you shake it loose.

I think that would be used for reverse bleeding. Is that what you wanted to do? For reverse bleeding, you would setup your fluid with a pump, attach that tubing, open the valve on the brake caliper and pump fluid into it.

 

[ryland]

no, I'm really stupid because it has these two adapters and I dont know where to put them?? They are just rubber end caps? I can put the clear hose over the bleed screw but where do the adapters go? Maybe I've inhaled a little too much brake cleaner?

One way facing the right way? Put the effluent into a bottle with some dot3 in there. and blow. BTW this stuff is poisonous!

So connect the long end of the tube to the bleed screw and thats it? Just pump the brake pedal? I have no idea what the adapters are for?

Here is a picture of reverse bleeding:

You do not pump the pedal for reverse bleeding. The pump forces new fluid up through the system. This is particularly effective for some hydraulic clutch systems, because it's hard to get bubbles out any other way.

the instructions say to pump the brake pedal I just dont know how to attach it?

 

[crw]

OK, if you pump the brake pedal then it's not reverse bleeding.

I dunno, just connect that open end to the bleed screw. The other end goes into a container to collect the old fluid. It must have that one-way valve on there so that it won't suck air back into the system. A good idea, when you think about it.

 

[ryland]

if it works, I just dont know what the adapters are for?????

I'm guessing the adapters are for different size bleed screws.

I saw this at HF and actually thought is was pretty slick. It works on the same principle as speed bleeders, except you don't have to replace your bleed screws.

Please post back and let us know if it actually works!

I just read the link:

* Two adapters to fit all bleeder screw sizes


So if the hose fits your bleeder, then you shouldn't need the adapters.

Also, there's this link for some pictures. Seems like it worked for these guys: http://landroverforums.com/forum/showthread.php?t=23074

Umm.. I'm going to take a guess at this one. I've used hoses all my life to bleed brakes, but nothing that fancy. Usually, I use some 1/4" line that I have laying around.

You just drop the line in a bottle of brake fluid - I prefer a clear jar, but a plastic cup or container will do. The hose must be submerged in clean fluid. The description states it has a one-way valve (very nice), so you don't need to be opening and closing the bleeder screw each time (I'm assuming that's the idea). This makes it a "one person" job. I prefer to make my wife pump the brake pedal and use the bleeder screw though. After each bleeder valve, I dump the container and begin with fresh fluid again. I suppose with the one-way valve, you wouldn't need to do that.

I just went through this process on my truck. Did it once, drove it a bit, then did it again. It's a good idea to do it twice because the second round looked about as bad as the first round. It took 2 quarts of DOT 3.

BTW, the pictures on that site are great.

The adapters should make it universal. I don't know what kind of bleeder screw you have, but just use the one that fits on it and don't worry about the other one.

If all goes right, you simply pump the pedal with the bleed screw open and the device attached [and directed in to a container].

So you don't waste your time, suck out the old fluid in the master cylinder reservoir first, and put in fresh fluid. Then begin your bleeding process. Keep it full - brake bleeding makes it go dry fast!

I would check the operation of the device to ensure it is not leaking, before you dive in. Simple ideas are often best. This looks like a one way vacuum line valve that was put to use for brake bleeding.
