It sprayed me in the face (that's what she said) and got on my fender paint as well - I had to scramble to get a towel and some cleaner to wipe it off quickly. Just a friendly reminder to check the condition of your equipment

Damn, those are tight bleeder valves. Did you mean 70 in-lbs?

Yes.

An option is to install speed bleeders. Some good & bad issues though!

NS370Z · 07-02-2013, 07:00 PM

A quick conversion gives 7.9 N*m approx = 70 inch*pounds or 5.8 foot pounds.

I researched these briefly a few weeks ago. Looked at Russell Speed Bleeders but I couldn't find a part number for the Z.

Yes it is 70 inch pounds per the manual (the wrench icon is black indicating inch-pounds not white for foot-pounds).

At 70 foot-pounds you would probably snap the bleeders right off (12x over spec).

thank you for the clarification... editing post now

I guess it's lucky I didn't have a socket small enough to fit the bleeder valves that fits my torque wrench

Hey JARBlue...what would you think if this cheapo process was done, say every couple of months (I mean it's pretty darn easy) instead of AK's 6 month rotation? By having more frequency do you think I'd EVER have to totally bleed the brake lines???

Also, my ride is a 2010 with 19K miles...do you think I'm due for this??

Thx in advance.

Quarterly is probably marginally better than biannually, but I'm not an expert by any means. With the right tools, bleeding the brakes in the proper manner is very easy as well. No, I would never consider that a permanent solution. The dirty brake fluid that is not siphoned out just becomes dirtier and dirtier over time making your efforts less and less effective over time.

I believe Nissan recommends 2 years or 30K miles, whichever comes first, for brake fluid change interval. If it's never been done before, it sounds like you're due.

It's not very effective, since the brake fluid doesn't really circulate as such. The crummy contaminated fluid hangs out in the end of the brake lines near the caliper and there is no way you are getting that stuff out without bleeding proper, whether it be manually or with a power bleeder.

OK, got it. Thx JARBlue and ChrisSlicks.

I'm going to piggy-back off AK's tutorial for the base brakes. The only contribution I have is that the front bleeder screws are 10mm and the rears are 5/16 (8mm). Used Valvoline Synthetic. Thanks AK for your write-up.

Is your car NON AKEBONO (non sports pack)? because for sports pack Akebono, it's 10mm for front and rear bleeder bolts.

Although his phrasing might be a little confusing, I'm pretty sure he is indeed referring to the base brakes (i.e. not sports pack). I can confirm that the bleeder valve for the Akebono brakes (i.e. sports pack) is 10mm both front and back

Btw... can I say something about the 8 month response delay?

yah and dont forget you got 2 valves per caliper on the akebono's
