Wondered if any of you knowledgables have had any experiences of this issue...
I have a set of ceramic front brake calipers on an Audi (which I believe are made by Brembo). The inner bleed nipple on both calipers have seized primarily I presume as the bleed nipple is steel and the caliper body is alloy causing corrosion between the different metals
The brake system has been bled religiously every two years.
I have a chap who has had success of removing seized / snapped bleed nipples so I'm not overly concerned about getting out - but should I replace them with stainless steel or titanium alternatives?
I have researched this on t'interweb, and I'm leaning towards a high grade of stainless with maybe a smear of ceramic brake grease or red rubber grease on the thread,  but there is some suggestion that titanium and alloy are possibly better suited to the different metals, although there will aways be some reaction over time.
I am a little miffed that dispite them being slackened to bleed every two years they have seized, but if I can reduce the likelihood of this problem in the future, which alternative metal bleed nipple would be best?
Thanks

I'd tend towards stainless, because you've only got to look at titanium bolts and they snap.


You are fitting rubber caps to keep the nipples clear? Most of the seized ones I've seen have been where the sealing taper at the bottom was corroded

Thanks Nick - they have always had the rubber caps on the nipples. Stainless was my thoughts too of the the two metals from what I've read. Checked the cost of them and they aren't too bad price wise either.
