Odd nipples

[jonzi]

I recently bought some Brembos from ebay.

Whilst I can get one nipple off, the other is stuck.


The nipple isn't one I have seen before. It's 15mm but rounding off.

Any ideas how I can get it off?

Got a decent vice you can grip it with and then turn the calliper?

Not what I was expecting. .

But good luck with it.

Whatever you try, I would first give the offending item a few sharp taps with a hammer, along the axis of the thread.
This will often jar any corrosion in the threads and generally loosen things a tad.
And its not as if you want to re-use the "nipple" .. which is actually a banjo bolt.
But I assume you've just removed that bleed nipple from it .. and I assume it was fitted as an aftermarket aid to brake bleeding.

If you have a vice, I'd hold the caliper in that, by the normal mount lugs but with wooden pads to prevent damage.
Then I might try an open ended spanner on it but my main guns would be a small "Stillson" type pipe wrench .. the sort with just one handle ... that self-tightens as you apply the welly.
Or else some Mole grips, but they can slip more easily.
I suspect you don't have a vice handy though ....?

If you don't have a vice you could always try clamping it to the edge of a bench or something.
If you have any clamps.
But it could all go wrong if the clamps slip.

And take into consideration the possibility of it being reverse thread. Not saying it is or it's likely, just saying...

love it when someone mentions reverse thread, then everything goes quiet fer a minute....

they often seize on ,,,,,using a vice to hold the capliper is a must also a little heat applied and a long tool for some real torque

I hit it with a hammer, then remembered I got a vice recently, so put it in that, and hey presto, out comes the banjo.

Thanks all

On a side note, what kind of crappy banjo was that in it? the bit that the spanner goes on to is a terrible design.

it was not a standard banjo jonzi, looked like an pneumatic airline banjo to me ,,,
