So does anyone know the minimum safe thickness for the rotors?
Their thickness is 28mm when new and the minimum allowed is 26mm. Basically they can only be machined once! A raised lip is a good indication that they need machining if there is enough thickness left in them.

Re: New Front rotors?
depending on how good you are with tools, whip the wheels off and have a yourself, normal rule of thumb to replace pads is when the friction material is equal too or less than the thickness of the backing plate of the pad. you'll need a micrometer to measure the rotor properly.

Re: New front rotors - ALREADY??
Hi all,
I noticed over a year ago (at around the 10k km mark) that my 2010 T31 TS had a slight shudder in the front brakes under sustained braking, even when I was using as much engine braking as possible. Last weekend I was in the Snowy mountains, I felt it again, but much stronger. Clearly warped front discs as I could feel it quite strongly in the steering wheel. My car has only done 33,000 kms! Not impressed! >
Whilst I have taken my car offroad, I have not done any significant water fording, so I dont think the hot brakes have been quenched at any stage. I can't say I've never been through a puddle with hot brakes, but surely that should be within design specs??
I went into book the car in at Nissan and explained the problem. I was sure this would come under the warranty, considering how young the car is. The technician at the desk said this is not an uncommon fault for X-trails, and said it was a symptom of their soft-roader design - ie, the brakes are designed more for feel and less for robustness. In the end he said he could not say if the job would come in under warranty, it would depend on the severity and their opinion on if it was driver abuse. What a crock! So basically it's just my word against theirs.
My first impression is that if they mention machining and it won't be done under warranty, I might save the dollars instead toward a new set of slotted discs in the future (the shudder is tolerable for now...). Worst case I will get my local mechanic the machine them at the next service - Nissan was quoting 66 bucks a disc plus labour. They can stick that.
The car goes in on Tues so fingers crossed they will cover it under warranty. Any advice on previous situations where this has or has not come under warranty would be great, I want to be able to argue my case.
Thanks - Mark.
PS The technician mentioned that slotted brakes are not recommended for dirt use as the slots gather up dust which then acts as an abrasive on the pads - any comments on pad wear from you guys with the slotted discs?

Re:
Hi Balio,
Unfortunately Discs, pads, cluych along with wiper rubbers and tyres are known as consumables and are not covered under warranty, no matter how old or young the car is.
As Nissan said, and we all know here on the forum, the rotors are very weak and do wear down quickly.
If there is a problem with the manufacture of the disc or a material fault, then yes it would be covered, but a shudder, I don't like your chances.
Have a read on all the previous posts and see how early the rotors are wearing on other members Xy's.
Good luck.
