Brake bleeding kit

[uclabiker06]

I got a one man brake bleeding kit (the hand one not the mitty vac) from the local auto parts store (need to change fluids).  Although the tube is too small to fit directly over the nipple of the caliper, it comes with a cone shaped adapter and it says in the manual that I'm supposed to stick that conical end of the adapter in the bleeding screw hole but I am worried that, that wont give me an air tight seal.  Any ideas?

If you take the bleed screw all the way out, your gonna end up with a mess.  Go back to the auto parts store and get a bigger hose that snuggly fits the bleed screw.

hm, okay.  Definitely will not turn the screw more than a quarter turn so I'm not worried about that.  I just want to know if sticking the cone shaped adapter into the bleeding screw (opposed to putting the tube itself onto the bleeding screw) is viable.

it worked when we bled elTristo's interceptor... but those cone things were like one-time use, and it was tricky to not knock it out the hole.

Perfect thanks.

The "brake bleeder" I bought at the local auto parts store was just a catch jar for the fluid and nothing more.  The clear plastic tube was too tight to get over the bleeder valve as well.  My solution was to warm up about two ounces of water in the microwave until it was boiling, then put the tube in there for about a minute.  That allowed it to stretch enough to fit over the bleeder valve, then I had a nice tight seal when it cooled off.

You've reminded me that it's time to bleed my brakes and clutch again.

No kidding,  yeah, well I ended up using that coned shaped adapter.  It actually works but you just have to press it in hard to get a "seal" and then go to work; might try your method for the clutch and front brakes.  I didn't even know brake and clutch fluid are the same thing.

Man a bunch of little bubbles cam out of that thing on the first try, then one bubble every two strokes then no bubbles.  But what worries me is that when I took the rear caliper off to bring it on the top of the rotor instead of unscrewing the retaining screw I unscrewed one of the two screws that are in the caliper itself a bit before I realized it.  I'm worried that let air in and I don't know how tight those screws have to be.  Can air get in that way? Anybody know the torque spec for the screws that hold the caliper together?
