This exact same bleeder nipple leak thing happened to me on the track to.

Is this consistent on both calipers or just one?

Same happen to my Z... in the rear left caliper last time I track the car. But was just a little :tup:

Depends on the track and your driving style. You could go from none leaking, to all of the nipples leaking.

Also happened on my 2014...running XP8's. Front two calipers at the same rate. I checked tightness between runs...in which both were extremely tight. Not sure if there is a torque spec for this nipples or not.

The torque spec on bleeder screws are usually in the range of 8 ft/lb's. And to further provide evidence of this, my front caliper's have done the same thing as your's. It's from the cheap caliper design expanding under high heat levels. However, i've not seen the rear calipers suffer from this issue. Did you have VDC turned off during the track day?

I've had all 4 calipers leak at one time or another. And yes, I track with the VDC off.

Same here VDC off all the time when i track my car

Interesting. I guess I just don't use the brakes that much on the dragon to get the rears hot enough.

Edit: To expand on this before any questions, I have only had the fronts do this twice. After the second time, I drilled not using the brakes as much into my brain again, as I had forgotten that when I went from my old eclipse with Brembo's to the Z.

VDC is always turned off for track day! :)

That's good. One thing you can do to help expel heat from the calipers is to use two piece rotors, and titanium pad shims. You can find a few two piece rotors for the fronts, but the rears are from Z1 only. the Ti pad shims can be found at Hard Brakes.

Turning off VDC does not turn off ABLS, which is responsible for applying the brakes to the rear wheels when it detects wheel slip. Since you're only experiencing this on the rear brakes, I would guess ABLS is the culprit. I think you have to remove the Stop Lamp fuse to turn it off.

I have the RC brake ducts, the Hard Brakes Ti pad shims, Racing Brake 2 piece rotors front and REAR. :D

^offset by the extra brake heat due to the grip from the ginormous big booty trudy tires :driving:
