you could have a loose zirc on a caliper too? have you lost any brake fluid since flushing?

The brake master cylinders are the same (D6010-JK02A).
The brake boosters are different:
Base = D7210-1ET1A
Sport/Nismo = D7210-1ET0A

Hoping the OP can solve his problem.

AND this is your PROBLEM! easy fix but that's the source. Since the booster on the sports z pushes more fluid and your z now isn't, that explains the lack of stopping power. Its the same idea behind electricity when you add multiple lightbulbs on one circuit and they get dimmer.

Have a lot of people going from base to a BBK actually upgraded their brake booster? I feel like this is the first time it's come up.

JARblue · 05-03-2013, 09:44 AM

very interesting that I haven't seen anything about the different brake boosters in the base and sport with regard to this upgrade...

I'm sure somebody would have mentioned it by now.

Z1 says you need a new oil line for the caliper (hardline).

I'll be getting it fixed in the next week or two. I've searched and people that upgraded never changed the booster.

Has to be a air bubble.

They talking about the stainless steal lines?

Just guessing myself but just from what I've read seems like a popular upgrade.

Ni55anPat · 05-04-2013, 10:30 AM

Yes there is a metal line suggested from Z1 to upgrade. Which I did.

diddy535 · 05-04-2013, 11:24 AM

Still soft?

Mike · 05-04-2013, 08:25 PM

this is a silly problem and thing to ask, but its a common mistake on brake swaps. Are the calipers on the wrong side? Its very easy to do and is almost always the case when my powdercoating customers have issues, although on some calipers, its not as obvious as on these. bleed screws on top.

Ni55anPat · 05-06-2013, 12:13 PM

Bleed screws are on top. Metal like installed. Just did a re-bleed 3 more times and its good to go.

Thanks for the help.
