When is someone going to design a replacement for Brake Bleed nipples?

I needed to bleed the rear brakes on my van today and as soon as I touched the nipple it sheared off. Soft as butter! SO off came the caliper, into the garage (in 12 inches of snow!) as tried the stud extractor. No joy! So drilled it out and tried a bigger stud extractor.. no Joy! heated it, cooled it, used every free-ing agent known to man... Nothing

What was supposed to be a 10 minute job has now turned into an epic voyage to try and find a new nipple on a Sunday, drill out the old one, fit a stud, drill that out and retap the thread for the proper nipple.

I wish there was a different solution to the useless things!

Today was supposed to be spend checking the valve clearances on the bike and it's been wasted on the bloody van!

Rant over.

welcome to my world, but at least mines the bike, but pain, so much pain, I feel for you.

Just read up on speed bleeders, never heard of them. Seems you still have to undo them to bleed brakes, its just they have a valve inside to stop air getting back into system

That's true, but I think they're meant to be well made, and if you're going to be replacing one anyhow, might as well add some convenience.

A good m8 and a bit of a bike guru said the way he bleeds brakes was to use a syringe and push the fluid up from the nipple. I'd give it a try if I could find a syringe?

use a long reach socket on the nipple to crack it open before you use a spanner. works every time with me.

Good luck finding all that on the Sunday, if worse comes to worst you could bleed it using the hose..making sure the hose is the uppermost part I think messy but works. I feel your pain I had aluminum 4pots on my mini can't remember the inns and outs but the nipple were steel the two metals fuse together making it impossible to get out resulting in needing new callipers.... The new design has copper ring in between the two metal by the looks of things!

Thanks for the replies! Oh, how I wish this was a banjo fitting!

... It isn't

I may well end up just tapping and blanking the nipple and bleeding it via the hose joint. I'll keep you posted.

... Off to swear profusely at it! See if that helps!
