Hi all.
I'm planning to replace the bleed nipples on my 4G's brake callipers as theyre very corroded.
Does anyone know what size/type/spec they are and, even better, a link to where I can find them?
Ive searched them but there's just so many variations out there... Who knew!

Thanks in advance.

last time i bought bleed nipples for front caliper i got the wrong ones - ended up using oem ones that i cleaned up before fitting.

I used to by my day to day braking consumables from brakeparts

The webpage is a bit 90s, but the parts catalogue, notes, model split and information are all really good resources. It will also list the thread sizes for the bleed nipples.

2 words of advice should you need them:

1) If they are really rusty, prepare for them to snap off in the calliper. I doubt the car is used as a daily or relied upon in that way, but make sure you have a backup plan / required tools to remove a snapped bleed nipple. Plenty of release agent the day before, maybe a little heat and apply force whilst its cooling and slowly work back and forth. If you have to remove the calliper to get at the nipple, you will need plenty more brake fluid to do a full bleed in the event the calliper is removed from the car (and air makes its way up the pipes to the abs modulator).

2) If this is some kind of track car where you will bleed regularly, I can highly recommend the speed bleeding nipples. These have thread lock on the threads, and a 1 way ball valve inside. This means you can self bleed the brakes by yourself, without having to disturb the bleed nipples too often. I bought mine from ebay and they were 10-12quid each and came from the states. They are probably a little more expensive now, but the ability to do it by yourself is worth its weight in gold.

Often you can look up the honda OEM part number and then from putting that into Google, find cross-matched parts or the thread pitch.
