A couple weeks ago I was changing brake fluid an notice that bleed valves are heavily rusted, so I ordered some stainless steel ones from this place in UK:

Much happier now.

That's a very good idea. It's amazing how many brake callipers have to be replaced due to corroded bleed nipples shearing off when trying to bleed the brakes.

Nice

A simple bit of preventive maintenance.

Probolt will probably wonder why there is a rush on stainless bleed nipples now  Too many toys, not enough time

Can you confirm the type you ordered please? M7?

CTC - M10 (1 mm),

Nino,

Your link shows M7 shallow seat... Didn't want members ordering the wrong nipples sir

Corrected, Thanks CTC

Nino,
Do the front and rear calipers use the same type and size of nipple ?

Mike, small visual difference (Brembo-TRW) but same size thread and length. PRO BOLT fit fine. in the picture left one is TRW

Nino,

I’ll be doing this to my Brembo front/TRW rears shortly after seeing this post and noticing how my bleed screws are close to seizing when I did a fluid flush the other day.

I assume that you just clamp the soft hose and keep a rag handy to minimise any fluid leaking and prevent air getting up into the system when fully removing the bleed screw? Did you use any lubricant or copper grease on the bleed screw threads?

TYIA! Andy

Don't use grease on bleed screw threads unless you're very confident it's brake fluid compatible (most greases won't be).
At worst some of the grease could get back into the caliper while bleeding and contaminate the brake seals cause them to swell & fail.
You might be lucky & it never happens, but I wouldn't risk it - especially if you're fitting stainless parts. Paul,

Seems like red rubber grease is the stuff for the job. Not sure of its longevity but I’ve bought a bunch of rubber dust covers and by mounting the retaining loop on the thread-side of the screw should provide a great seal to keep the road grime out and grease in! 🤞

Have never thought about replacing for stainless before, great idea!
