370Z clutch line restriction

N0SL3N · 04-05-2013, 12:52 PM

Do you have a link to the parts you used?

Also this is located inside the drivers side wheel well?

is this 'restrictor' only on the 2009-2010 models?

No, this restrictor is on every model year, '09-'14. Its even on GT-Rs.
Its only a $4 part. Install it when you do your next clutch fluid, plastic POS CSC and/or clutch change.

but... the R35 GT-R has no foot operated clutch?

The same part is also used on various auto trans Nissan models.
I'm guessing it could also double as a brake line coupler and that's where it might be used on the other cars.

If i'm cracking the lines open i'll be replacing it with a braided stainless one for the consistent pedal feel. But i don't enjoy the idea of cramped work space (no hoist) and brake fluid spewing. Maybe i'll just drain all the fluid first hmmm

That's correct. On other Nissan models such as the GT-R (R35), Q45 (F50), Pathfinder (R50), QX4 (JR50), M45 (Y34)...its used as a front brake fluid restrictor, I mean "connector".

this might be a dumb question, but why would a restrictor be necessary?

In a brake application, it would impede the function of ABS pulsating the brake.

In a clutch application it would as people have noticed, make the pedal feel inconsistent and delay clutch action.

Is it to reduce frothing from fluid rushing back too fast?

Most folks who have upgrade to a braided stainless line report smoother and more consistent clutch pedal feel. As expected, a lot of the consistency is due to the stiffer walls of a stainless braided hose but these replacement lines also eliminate the hard line that goes between the stock flex hose and the slave.
What is the purpose of this short section of hard line? (i guess the same question should be asked about the way the brakes lines are connected to our calipers - why is there a need for a short hard line between the rubber hose and the caliper?
