Re: My Nipples have broken
I had this on my old Fiat 127 years ago, tried drilling one, buggered it up, the other an eazitout, snapped off. Lesson learned.
In the end, down the scrap yard for some replacements, there are enough Alfas with knackered bottom ends to make second hand ones viable and freely available.
As you have snapped three maybe there are some builds I can offer to help future problems
1. buy a 8mm socket with six sided rather than the normal 12
2 use a T bar so the pressure is evenly applied, if using eg a ratchet there is a tendancy to stray off the vertical and that is when they snap.
3.soak the bu99ers in WD40/releasing oil the night before.
4. sustained pressure is what snaps them, a sudden twist will free them up. Also try tightening them a fraction before undoing them to release the rust or hit gently with a soft faced hammer.
I am sure the 145 brakes are the same as GTV/156 unless you have a very early car if that helps.
