370gt Sedan Brake Pads

[nickcorr]

I assume you have the standard 320mm brakes Nick?

I do indeed mate... With the twin piston calipers. Not like the 350GT Sedan which came with a 330mm disc, but only single piston calipers.

I had shuddery brakes on my 370GT Crossover (J50) and just had them machined (along with new lower control arms - don't ask!) and the shimmy is completely gone. Didn't even get new pads.

Hey Nick, any updates?

[nickcorr]

Pads and discs are sitting in my garage...

Will get them, and the used, but better condition than mine, propshaft doughnut coupling bought from the US, fitted in the New Year..

[GFXman]

update?

[nickcorr]

Still sitting in my garage..

Local mechanic is relocating to new premises so will be over there when the lifts are all connected and working.. Should be in the next 2 weeks..

[GFXman]

So I ordered the parts mentioned here and they didn't fit my car

Typical

What parts? Discs? Pads? Both?

You didn't take a wheel off and take some measurements to double check? I always do that on the first purchase when it's something that's not as commonplace as a Fa(i)lcon or Bomb-o-dore.

If there's one thing I learned as a student from my first boss in the broadcast business, it was "measure twice, cut once". Now you've learned the same.

[GFXman]

Both

Foolishly no; I had faith LOL

Live and learn

Surely it doesn't make sense that a 2009 V36 370GT would have 330mm rotors? Weren't they only on the V36 350GTs?

I know they're definitely not the akebonos...

[The Max]

You are right. The 330mm discs were for the older beasts whereas the 2009 sedan got the 320mm instead. The only theory why I suspect 330mm might still be an indicator is because in the US, the base model coupe had the larger 330mm discs in their 2009 model but the sedan still got the 320mm. That's not to say that their years lined up with the JDM spec though. Unless I got the wrong information, I found that my 2009 model, though built in Dec 2008, was released as a 2010 model in the US.

Problem is, I'm trying to look up the current DBA catalogue for further confirmation of numbers but they've severely trimmed down the Infiniti options and there's not as much detail as there used to be. It only lists the sports package, which is 355mm front and 350mm rear - that's what I have on my coupe.

It's odd, given that DBA still list discs for the G35/V35 but cut down the G37/V36 to just the sports package size in their catalogue. Curious stuff.

And I ordered 320mm rotors. Odd.

[The Max]

But you got given 330mm or the 320mm proved to be too small for your vehicle?

[GFXman]

Well I assumed they are 320mm as ordered... will double check tonight. Mechanic didn't say; just said they don't fit.

Clearly I put too much faith in people who I assume should know this stuff. To be fair I guess they're a hard car to get parts for.

So frustrating

Ask him to measure that the disc rotor on the car so you know what to buy next.

It's just a matter of doing the homework. I've given up on trying to track down the older DBA catalogues I thought I had on file. Here's what I've found in the 2010 G37 Sedan workshop manual http://www.nicoclub.com/FSM/G37/Sedan/2010/BR.pdf (Nov 2009 revision of the manual itself):

• Front Caliper 2 Piston and Rear Caliper 1 Piston type:
  • Front rotor outer diameter - 320mm x 28mm
  • Rear rotor outer diameter - 308mm x 16mm
• Front Caliper 4 Piston and Rear Caliper 2 Piston type (in other words, the sports model):
  • Front rotor outer diameter - 355 x 32mm
  • Rear rotor outer diameter - 350 x 20mm

Again, it's worth taking the time to take a wheel off and measure it for yourself to confirm or get your mechanic to measure it up for you while he's at it but it's safe to say that if your mechanic said they don't fit, the discs you got in were too big.

Screw that! I've always been a firm believer in people helping themselves and if they do end up slipping in their own shit, then I'll step in to help out, knowing that they tried.

This is why, I might be a search-Nazi when people ask the same question over and over again but I do practise what I preach.

[colin.ssc]

^ never had a problem with that...same thing for me. As long as they prove that they had tried searching but have more questions / doubts or confusion I wouldn't mind helping out.
