Replacing brake bleed nipples

[paulj]

I was replacing brake fluid at the weekend and although all nipples unscrewed, one would not allow fluid to flow.  It looks like the oldest one and needed WD40 to unscrew in the first place.

Can anyone tell me the correct one to get as a replacement, there are lots of generic ones on line.  Do they all have the same thread etc?  The one to be replaced fits an 8mm spanner and on my car I have a mixture of 3x 8s and 1 x 7.

It's a rear brake assembly if that makes a difference.

Thanks for your help

If you whip the nipple out, you can probably clear the muck out of the hole.

The nipples are a pretty standard, many-car item.

Thanks Carolyn

I think bought of trying to clean it but when I realised they were so cheap it seemed better to do a replacement!
