Hi to all,

Finally, just got my v35 250gt last thursday. I've been observing it for a week now, so far it's all good. There's just this one thing bothers me about my breaks. The car vibrates a little bit whenever I slightly step on the break pedal to slow down coming off from 80-100 kph.

Is this normal? Anyone had the same experience before? Am I just making a big deal out of it? Coz the car drives awesome and the breaks are working really well, except only for that little vibrate thing that I'm worried about.

Any suggestions and recommendations of what to do would be big help for me. Thanks!

before you shell out your hard earned chasing the worst case scenario, consider giving them a light skim with some wet and dry then a clean with brake cleaner. You may find some pad resin has been left on the disk surface from poor braking habits. This happens when the foot is left on the pedal when the brakes are very hot. If this doesn't cure it then they may need a machine skim. There are plenty of mobile brake mechanics that can do this without removing the disks.

Me too have a vibrating brake before on a 4WD, and I found out there's a hair line crack on it. Have to change the whole disc. I was told maybe the crack was due to sudden cooling of the disc. Like after a heavy use, car was send to a car wash where the water jet cooled the disc too fast.

+1 for a rotor issue, (most likely warped), as it's the only issue (other than an ABS fault) that will cause vibrations under braking. Does it get worse when the brakes are hot?

Not really, it only vibrates for 1 to 2 seconds if I slightly step on the break pedal and only if I'm driving a bit fast.

I'm thinking if this is a serious problem, I might bring it back to the car yard I bought it from and get it fixed.. Can I still hold them responsible for any problems with the car? Since it's only been with me for a week now and because they told me that it's been complianced so I don't have to worry about anything. Is that possible?

It came with a warranty yeah? Depends on how good the dealer is, as a rotor problem (if that's the case) could be dismissed as normal wear and tear. Only 1-2 seconds? Does it then go away completely or just become really faint?

I think it does come with a warranty. Well, it should be.. It doesn't get any worse after those few seconds. It's hardly noticeable tho. But I better get it fixed before it cause me bigger problems in the future.. I'll ring up the car yard tomorrow. Thanks guys for the help. cheers.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
