It’s something we always wince at. Every car gets a brake bleed but you can tell the ones that are going to snap so they get left. We think its from where the brakes were not or never have been bled before.
Before you give up on it, it’s with trying to tap it out.
As it has a central hole in the sheered off bit it’s worth a go or take it to an engineering firm.
you need to set the depth you drill as the base is tapered
File the snapped bit off flush, get a new nipple and measure the thread, drill out with a 0.5 undersized drill then run the tap through it.
fill with fluid via the working nipple then push the pistons in to purge any swarf.
Yeah, I think you're right. It must be the lazy bleeders in the garages! It's nearly always the inner bleed nipples too. I didn't have the option of leaving it, as I'd replaced the brake lines with braided and was changing the fluid to RBF600.
Great advise though Matt, thanks.
@conaero.
I've had it with a couple of my previous cars too, but always managed to succeed eventually, whether it be with heat or re-tapping.
The problem I had with this one was unfortunately even with the diamond drill, the broken easy-out steered me slightly off centre so by the time it was all out, it was never gonna seal again as the orifice was off centre in the tapered seat.
In hindsight an engineering firm almost certainly would have done a better job with the right equipment, but having never failed with one before, I just cracked on with it lol
Anyway, I did source a spare, but unfortunately it still hasn't arrived yet. Tomorrow hopefully.
