I just got my first set of Shimano brakes on my new (ish) bike, XTs, and had to lengthen the hose as the muppet who sold it to me had the rear lever about 2.5" from the grip. Sliding it to the grip caused it to be too tight, so I got another hose and the bleed kit to do the job.
Can someone explain to me why Shimano are so inept as to still use a bleed nipple and a tube that just slides gently onto it, and will pop off at the slightest pressure to spray fluid all over me and everything around me?!? At least it is mineral oil and not DOT fluid, but really!
I have been using Avids and Maguras for the last several years, and am used to a screw fitting when bleeding. Much easier and more efficient.
I did get the job done eventually, but what a pain! Grrr!

Anyone had this problem and found a cure? ( he asked, knowing he'll have to do this again some time...)

The REAL Shimano bleed kit has a clamp that goes over the hose, over the bleed nipple. I guess I have spent too much time racing cars and working on automobile brakes to think the bleed nipple is bad.

You can also take the brake caliper off of the frame, let it hang and gravity bleed the Shimanos. Use the funnel on the lever and call it a day.

I am not sure what could be easier than gravity bleeding brakes.... you literally only open the bleed nipple at the caliper. ;-)

The long black thing near the end of the hose is the clamp that locks the hose on the nipple. If you are still bowing it off, you are pushing WAY too hard on the plunger. I suggest you gravity bleed instead if you have gorilla hands. :-)

And this is the bleed kit you should be using, not the cheap one without the funnel:

This should start the video at the point that shows the clamp (Nope. Didn't work. Skip to 1:28 for the clamp). I have never had a hose pop off with that clamp in place.

That's the kit I have, but the clamp did not fit over the nipple. I tried, believe me! Maybe I have a defective one... That is actually a pretty good video for the task. I have watched several and it's kind of funny to see how each one differs!

In the end I did do the gravity bleed too, I attached the syringe without the plunger and with a nitrile glove zip tied around the syringe body to collect the oil. Worked good!
Next time will be easier, but it is working great now!

While bleeding my wife's brake sin our dining room, I forgot I had the hose completely detached (don't know how I forgot) and squeezed the lever..... that fluid shot about 8 feet across the room. I don't bleed in the dining room anymore.

Hahaha! I can picture that!

Once I bought a brand new Ducati 900 Monster, and was so stoked I parked it in our front room while I went away on a tour for a couple of weeks. My (ex) wife was uber pissed at me 'cos it stank up the place of gas... took ages to get rid of the smell...
