Brake Rotors

[discovery4]

Dear All,


I have just had a 'health check' done at 38000 km on my 2013 SE D4 and have been told that the brake pads AND ROTORS front and back need replacement!


I was concerned that the rotors are wearing out faster than the tyres. No, I am not a harsh driver and have only towed a camper trailer (about 1 tonne) for a total of about 4000 km.


I am told the rotors are not covered under warranty and cannot be machined. Any comments from experienced owners?


Thank you
Bob

Doesn't sound correct. My D4 front rotors have just been replaced at 160,000km and the third set of pads were installed. The previous pads lasted from 80,000 to 160,000. The rears wear quicker on my car and I think the rotors were replaced at less than 100,000. I seem to use two sets of rear pads for one set of front.


I have a 3l SE with the larger brakes. Not sure what yours is but this may make some difference if you have the 2.7 with smaller brakes.

They always say the rotors need doing and they may very well do - ask them to show you the numbers. They said mine needed replacing at 60,000km but I measured them and they were only a 1/3 worn - still going OK 30,000km later.

Min thickness of a D4 rotor is 27mm. I replaced my own at 60000km.

Thanks for the comments


The reason the dealer is replacing the rotors is due to wheel vibration under braking. Mine is a D4 SE 3L MY13. They also said with the rotor change that the pads would be changed also.

If replacement is required at 38k, due to vibration, I'd be saying that's a warranty issue!

[BobD]

I agree it is a warranty issue.


My 160,000km old rotors had zero vibration and I have done heaps of creek crossings at Cape York, Litchfield National Park, Power Line track in Perth, Kimberley Rivers etc etc. The only reason for replacement was wear close to the minimum limit at the time of the service.

I had my front rotors and pads replaced at 20,000km due to steering wheel vibration when braking. Have not had a problem since, now at 30,000km.
Originally reported problem at 18,500km, but took a while to get them to do it under warranty.

The rotors can be machined, but the allowance is fairly small. I have just had my rear pads replaced and rotors skimmed at 52,000 km. However, if they are chasing a vibration then they may not have enough meat on them to machine.

That said, something doesn't sound quite right. Changing all 4 rotors to solve a vibration problem seems a bit lazy. If the vibration requires 4 new rotors at those kilometres, I would think a warranty claim should be worth pursuing.

Cheers,
Jon

94K in and on 2nd set on rear (recently machined) and 3rd set on front.. it also depends on where you drive, i did not need anything for the first 60K as mostly long distance driving, last 34K has been basically in and around Sydney so more wear and tear and hence time to change..

My first set on my MY06 Sport lasted a whole 19K
