This doesn't seem right. Will be getting them replaced next week, but should they get this bad?

na, part of a Brembo brake kit from Free Spirits. Just checked when I got them, and its almost 3 years ago. For me that about 50,000 kms so I guess well over due for replacing.

I had a set of Brembo full floaters, always had some movement but as you've found after around 50,000km for me the play became excessive, similar to that. (They were still warrant-able but damn they were noisy)

wait so its OK for discs to wear out before a set of pads these days? What is this a Nissan Navara ute?

A mate was telling me every time he had his Navara serviced they used t replace the rotors, i said WTF.

The first and only Navara ute a mate of mine had was the same - 50000k out of a set of rotors.

He went back to Toyota after that but now has a Ranger. Cliche but according to him the best driving and best value. Its a biggish beast tho.

Not uncommon. An acquaintance insisted his flash ford was dealer serviced and they replaced all the discs every 20'000km's.

Never knew Cadburys made brake discs.

After watching your vid OP I really need to check the discs on my GG, more rattles than a millionaires baby.

It's not that the disc material has gone soft, rather it's the traction control and stability controllers on modern SUV that use brakes for modulating power to wheels. Most modern cars now wear out rear brakes when previously rear brakes last forever.

Understandable, but the Rangers and the toyotas run rear drums not sure the navaaras.
but we have never had to constantly replace the fronts on the Toyotas and rangers like the Navara's seem to need.
TBF the Hilux we run have only had stability control since around 18/19.
My mate said the navara was actually warping the front rotors.

One thing i noticed the other day when looking at his new up-speced ranger with its kick ass bigger wheels diameter, as although they have room for bigger rotors they really use this space for them, so those cool 22 's here has have less leverage which works the brakes harder.
i wonder if that was what is happening.
My Toyota's only on 17's

The 2 theories I had were either stealership revenue or manufacturers using hard pads and soft discs to save money.

T'was just a thought.

Driving style has a lot to do with it. When I first serviced my current car with about 80'000 km's on it I was told new discs and pads next service. 155'000kms and still no brake work. It has all the fancy driver saving features, too.

Not if they specced the 22 inch wheel/tyre combo properly



Fastbikegear did a couple of runs of Alloy Centres for Brembo discs as the originals wore too fast

No idea, it was brought as a brand knew wildtrak
The brakes look like tea cup saucers.
it's pretty much exactly the same as the last up-optioned 2019 std non wildtrak one he had other than a than interior leather and piping from what I notice.

you see more brakes than I do Warwick, but looking here, the rangers std or wildtrak all have the same size 302mm rotor dia?

the raptors have rear discs and bigger rotors though.

Way back when I worked on cars, VH Valiants were prone to warping their ventilated front rotors, resulting in a pulsing pedal. The fix was to have them skimmed and they would never be a problem again. Never replaced any on vehicles of that era. Maybe the iron is softer now.

The ritual for the cast iron rotors in the early 80'sGp bikes was to use them then by hand spend hours rubbing down the high spots that appeared before using them in anger something to do with the grade of cast iron that they used?

i wonder if it was for the same reason.
Modern brakes don't tend to fade like the old ones maybe its just the pads being sintered metal and ceramic rather than asbestos and organic.

It's not. Had exactly the same condition to one of the front OEM Sunstar rotors on my 05 Speed Triple. Flogged out the carrier, however the other rotor was perfect? Still have those rotors somewhere floating about.:)

I figured at the time there may have been a bad batch of alloy to make the carriers?

That's true but some modern rotors warp! The front rotors on my Duke 790 did that. The problem surfaced quite quickly from new. They were ok at open road speeds but extremely snatchy at low speeds. I took some readings with a magnetic base DTI, photographed the markings on the discs and then visited Boyds in Hamilton where I bought it from. They supported a warranty claim and new ones were supplied by KTM. Now better than they've ever been. Fitting EBC HH pads made a big difference too.
