Rear brake pads wearing faster than fronts?

Anyone had this happen? My '12 has 26k miles, and at its recent service they said the brake pads are at 8mm front (fine) and 5mm rear (will need replacement in the near future). It seems odd to me that the rears would wear out before the fronts, unless the brake bias on these things is set up in an unusual way.

that's pretty normal considering the weight on these rides. I've had to change my rears on my RRS twice and changed the fronts once since I've owned it.

Thanks for the reply. I understand the weight wearing brakes faster. I was just under the impression that with the weight transferring forward as you brake physics dictated that more of the weight is borne by the front axle and therefore front brakes, which has been my experience with other cars in the past. But maybe the system is set up so that the rears clamp earlier or stronger or something.

My Volvo wagon had the same setup. Back brakes grip first / harder to prevent nose diving.

Yes, and Andyboy said, it is fairly normal and counter-intuitive. Perhaps the rear pads are thinner to begin with....

Hadn't thought of that possibility. Well, whatever the reason it sounds like it's not unusual on the LR4. I was mainly just wondering if the tech who measured them made a mistake, and it sounds like the answer is probably not.

Yes, that's quite normal for these vehicles. It's a combination of the front brakes being substantially larger than the rears on the LR4, along the "intelligent" braking system designed to minimize nosedives when braking. I have also gone through more sets of rear pads than front ones so far (although discs seem to last about the same amount of time.)

is there a typical life span for rotors? I was hoping for 100k miles. Might be optimistic. 2012 LR4 with 53k miles new rotors and pads as a CPO with 33k miles. Still seems perfect.

It all depends on how and where you drive but yeah, 100K miles seems a bit unrealistic even in a best case scenario. My rotors seem to last about 2 changes of pads on average, so anywhere between 40K and 60K miles or so, but that's my driving style (city / highway mix, lots of traffic, hot and dusty conditions, 30-35K miles per year.) YMMV.

Are the front brake pads bigger on the LR4? I recall the pads being about the same size front and rear on the LR3.

I'm not sure that the 'intelligent' braking system part isn't just made up by someone in marketing somewhere. The rears have been wearing out sooner all the way back to my '91 Range Rover County, which was cool in a lot of ways, but certainly not intelligent at all!

That said, it's kind of strange, and I think there's a lot of ideas. But in the end it just is what it is and you're good to go :)
Carry on...
