(Bmw r80 1978 ATE swinging )My bleed nipple was on tighter than a tight thing holding onto something very tightly , tried heat, wd40, more heat, soaking in wd but net result was the feckin thing snapped off - I drilled a pilot hole and tried an unwinder tool but that wouldn't shift it either so I drilled bigger and bigger until 8.2mm and all that was left was the threads and I got it all out -

On one of the smaller bits I drilled too far down - didn't think it would matter as the 'collar' was still big enough to seat the nipple.

Big doos and little doos it doesn't leak fluid but leaks air .

I think the threads are too shallow now and the nipple is not a tight fit.


What are my options?? Second hand caliper?? ( can't afford new) drill bigger hole and use bigger nipple? Helicoil type thread repair?

Or petrol and matches???

The nipple seats at the bottom and not at the top. It looks like you have damaged the seat that the nipple seals to.
 
I'd be contacting either Motobins, Motoworks or James Sherlocks for a second hand part.
 
Sep at kegworth fix them for £15. There must be someone local who can sort it for you.

wd40 is s waste of time for that application. Plus gas is the thing to use.

Ask Andy (number6) he's a decent bloke who restores Brit bikes. I'm sure he'll point you in the right direction
