I found out I need all new bleeder caps for my G37s(for akebonos) apparently I've never had them on my car since I bought it. I called up the dealer and they said I have to buy all new calipers which comes with the caps(what a joke....) I tried some autoshops around my home like autozone and they said they don't carry them for my car so I need to resort to something else.....

I tried ebay and typed in "akebono bleeder caps" but none was specified towards my car. I need a second opinion or if someone could just like me to buying another.

 

I got , they work okay.

 

Not sure how big your bleeder caps are but for my Wilwoods I bought these and they're perfect, and come in packs of 8 shipped for less than 6 bucks.
