when I am driving, no barake applied...there is a light squelling sound coming from the front right rotor. It sounds like metal touchin metal very lightly and disaapepears at high speeds. then comes back at low speeds. Not sure what it is.

why does it do this for at varying speeds. Its a light noise but annoying. I had my discs machined a few months ago.

But same barke pads in since 75,000...and the car has done now 136,000.

any ideas?

i get the same noise all the time apart from when i am using the brakes reasonably hard. Mine make it from the front right as well, and you can hear it from a car in the next lane going 70!

my pads still have heaps of meat, im assuming the pad material for some reason has gone funny and is making noise agaisnt the rotor?

The noise may not disappear you may just not hear it if the noise from the car is drowning it out.When you hear the noise rest your foot on the brake pedal to see if it goes away and this will tell you if it is a problem in that area of pad and rotor making contact.

I take this comment back. Pulled off the pads today and it was the wear indicators. They start touching when there is still maybe 2.5mm of pad material left, i cant believe the pads ran out so quickly in any case, the drivers side has been touching for a while and the passenger side is starting to touch.

Sometimes it can be the simple things that are the problems.What brand of pads are in there ?

I fitted new pads over the weekend for the same reason (wear markers annoying me). I still had, I reckon, about half the pad material left.

Bendix ultimate, less than 20,000kms, one track day only.

the pads have approx 2.5mm pad material still left.. as a guesstimate when new they were about 15mm thick.

Why not just bend the wear indicator back a couple of mm? That's what I do.

I bent the damn indicators back with great satisfaction to finally shut them up :laugh::huh::) i have new discs and ferodos waiting to go in in any case :)

Great to hear it worked for you. In any case, whenever indicators are bent back, always remember to check pad thickness regularly to make sure you don't get metal on metal at some point.

      Reading your posts Josh, sometimes I feel like I've gone in a time machine back to the 90's when everyone was doe-eyed and figuring things out for the first time.  I've lost track of how many single turbo GTR's I've seen on track that haven't burnt down lol. Everything has been figured out a long time ago. These things are at the point now where its essentially turn-key to go single turbo.

      Among other things yes. Making sure to either use an oil pressure regulator or the right restrictor size for your oil pump/range of oil viscosities you intend to run, making sure you plumb the lines correctly, turbo should be placed such that it siphons properly even when the water pump isn't turning so you don't boil coolant in the turbo after shutdown, oil return should be low resistance and also preferably picking the one that is most likely to return to the pickup as opposed to some other irrelevant part of the pan. It's far from impossible to figure this out but I have seen people really, really struggle and if that's the case it's easier to just take the path of least resistance. To me, bolt-on twin turbos are a fixed cost whereas single turbo is almost unbounded.

      Latest round of updates on the car. I purchased and installed a SWS clutch slipper to help with 60ft times and got some second-hand good condition 275/40R17 Hoosier DR2 radials. Test and tune in November showed the tyres were an upgrade over my over 15 year old mickey Thompson's and I got a 1.8 second 60ft and pb et of 11.71 but even then, that run wasn't great due to rain and driver error (the event got called off 10 minutes later fast forward to the weekend just gone 25th of Jan and there was finally a break in the weather to let racing happen. The first run the track was slippery and only managed a 12.1@129 Second run the track was better and got a new pb et and mph: 11.54@131   Lith and I then worked out that I installed the previously mentioned clutch slipper incorrectly and its never been working, and I had just been dumping the clutch the entire time, we also noticed it was on street boost and not race boost. So I lined up for a third run with the car turned up in the first two gears, but the passengers side axle objected to clutch dumps and left the chat which stopped my weekend.   so there will be another attempt in the future once I replace the tyres as they rubbed and are stuffed now. but a low 11 should be on the cards.

      Turbos don't require pulling the motor apart so that's "easier". I would recommend the Nismo R3 turbos instead if you want to do stock twin turbo. It doesn't make as much power as the 2530s but it's only like ~50 whp off the mark and should have better response (ball bearing CHRA, slightly smaller turbo). A local that went with a Garrett G30 and 6boost manifold recently nearly burned his car to the ground after the hood insulator started melting and and burning so if you go single turbo I recommend doing a lot of research and validation work to make sure you don't do the same.
