Re: T31 Series 4 Front Brake Rotors


But this time they were right Tony!

I got all the way to the GM of customer service today and got access to the photos that were sent of them of my pads and rotors and I got convinced that what I have seen was nothing more than surace burn marks of a very hot brake pad, as the pattern is identical.

The photos speak for themselves:

In this case and for the added peace of mind I was happy to pay for the light surface machining of all 4 rotors and the burn marks have disappeared in full.

The quality of these rotors is definitely not any better than the T30 ones, if not worse!

The next time I touch these rotors will be when I swap over to the DBA slotted ones emoticon

Re: T31 Series 4 Front Brake Rotors


Ah well, at least the bogeyman of disintegrating rotors has been put peacefully to rest...

Edit: the more I read about these factory X-Trail rotors, the more it becomes apparent that they are provided by Accountants, not Engineers.

I think it is generally agreed that they are not up to the standard which should be reasonably expected by the consumer.

Although 'worlds best practice' may consist of getting the cheapest parts from the most underpaid at the greatest volume and the lowest prices with the cheapest materials - I do not see that as a positive effect on either consumer confidence or actual ability to perform a given task.

The consumer will be negatively affected. This forum is starting to show that.

That will lead to a negative effect on sales of all vehicles tainted by a brand name which willfully destroys the faith of its most fervent admirers to save a dollar.

Alienating the support base is never a good idea.

That sort of short term thinking causes a medium term cost of sales losses a million times more than the annual accountants book ~ balanced ~ paper figure saving when the juggernaut of negative consumer experience begins to roll.

Long term - hundreds of millions more to reverse the momentum of general adverse perception.

I would hope that Nissan was not so foolish.

Re:


It seems the pads have a lot to do with the 'cracks'.
Looks like they got fairly hot one day and the car was stopped for a wile, the build up of brake dust in the grooves remained as part of the glazing.

Were the lines only on one spot of the disc?

That's what Nissan technical department said as well and yes the lines are only on one spot of the rotor.

Re: T31 Series 4 Front Brake Rotors


I know it is an old thread but my recent experience is that the Series IV brakes disks are not up to the job. Just got back from a trip over the top from Bogan to Dargo, not going fast or loaded up, brakes cooked and serious shuddering. Car only has 18,000km on it, traveled in convey with two Prado's and a VE Commodore Sedan, none of these has any problems. NOT HAPPY! Will tackle Nissan about it when it goes in for it's 20K service.

Rotors


Another reason rotor life is reducing is that manufacturers are making rotors thinner, chasing weight savings to achieve better fuel economy.

Re: Brakes


I've done the DBA Slotted Rotor / Bendix 4WD pad change at the 10,000km service. The difference was immediate and quite noticeable especial when panic stopping from hwy speed.

Forget machining standard rotors. If you can tolerate them for long enough that they wear out, do not put new standard rotors back on.

DBA Slotted Rotors are cheaper than the genuine crappy rotor, The DBA Slotted Rotor will decrease stopping distance and improve vehcle safety.

There's no rational argument in support of the Nissan standard rotor, which is often out of stock Australia wide anyway!

Re:


Please dont think this is any different from any other vehicle.

I have been driving for over 40 years now, Holden, Ford, Toyota, Nissan, Mitsubishi and Honda.
All of these cars exhibited pedal pulse at some stage.

Ford were the worst, had the rotors machines twice and replaced at 30k
3 months later the same again (this was a brand new XT Falcon).
Had aftermarket rotors fitted, and drive for 2 1/2 years with no problems.
Previous fords and most noted the AU falcon were all juddery and pulled to the side, not fun.

Holden, the first car I had ever noticed with brake judder, my previous cars were all drum brakes, a whole other story of fear and trepidation. (You aint lived until you try stopping a drum raked car after running through a lot of water)
I replaced the rotors of my Holden with DBA rotors and it never juddered again.

Toyota lasted 2 yerars, Mitsubish nearly 2 years and Nissan 18 months before judder started, and in all three, machining of the rotors was a very temporary fix, generally less than 3 months and it was new rotors.

The Honda lasted the longest, nearly 5 years, but again machining was very temporary, less than 3 weeks before the judder started again.

Most of my driving is highway intermingled with about 20 klm a day of peak hour traffic.
I drive 86 klm each way to and from work and about 200-400 klm on the weekends.
I tow a 1100kg boat at least twice a month most months, the ford hated towing this thing but the Exy eats it up.

I dont speed....much, I dont play racy racy, I dont brake hard as I always give plenty of space, but there is still the occasional idiot that makes me brake a bit harder.
I have been driving the Exy for 5 months so far and still not felt the antilock go off yet.

Original brakes are crap on all cars, not just nissan. It this reason why DBA sell so many brake rotors.

Enjoy the Exy

Re:


Replaced the exy front rotors on the weekend with T2 DBA brake rotors and 4WD pads.
Much nicer car to drive now, not even the hint of judder.

Easy job as well.
2 hours total and a goodly portion of that was cleaning the bits and pieces.

The old rotors looked near new, still plenty of metal left and no evidence of wear step.
the pads were half gone though.
I purchased the car second hand, (93000k) and the service history stated that the brake pads were changed at 60000k, obviously the car had not been driven too hard to get life like that out of a set of brakes.
No mention of rotor replacement or machining.

Bleeding the brakes was a bit of a chore.
I like to flush the whole system, but because of the weird way the master cylinder tank is set up I couldnt drain all the old oil before I started, even with a siringe there was still half left.
Unfortunately, the new fluid and the old fluid were the same colour, so I couldnt even see when the new stuff was coming through the bleeder.
Ill get some new stuff later of a different colour and start again.
