I expect the QX60 is set up the same, keeps the car more level, stops the Big Gulp from spilling from the cup holders Top This problem may occur for several possible reasons. I'm assuming this is caused by the stability control system on both vehicles. If the discs/pads are smaller, they can wear faster. Normally front pads wear faster than rears if fitted at the same time, but as always this depends on the brake design,how the car is driven, the materials of pads ,plus the conditions the brakes have to endure along with their maintenance schedule etc. Plus these trucks have more rear bias compared to the older ones. Rear brake pads generally have less surface area than fronts, and as such, even though they are doing less braking, can wear through the pad faster. Very light brake use probably wears the rears faster. In vehicles with a conventional proportioning valve, the front brakes typically wear two to three times faster than the pads or shoes in the rear. Tire rotation is the solution to even tire wear in a front-wheel drive vehicle. Front and rear brake pads will naturally wear differently because they are designed to perform in separate ways. On my '03 I averaged 30kmi on the front brakes and half that on the rears (which usually needed one of the calipers replaced at the same time). Anti-lock brakes work best with disc brakes because they release quickly and smoothly. Unlike front brake pads, most rear brake pads wear down faster due to the brake mechanics of rear wheel commute cars. I noticed the rear pads on my 2012 JKUR getting very thin at 31k. I was surprised to see the rear pads were down to next to nothing but the front pads had plenty of meat left on them. She released one album entitled Rear End in 1999 on Master P's No Limit Records.

If your traction control kicks in a lot, it can cause the pads to wear faster. This is done because, as previously stated, rear brakes do not require as much braking power. Changes to shoe design and placement have helped drum brakes release quicker, but discs are still better. Under inflation; Poor tire alignment; Wrong toe settings Consequently, a .

Your front brake pads will also wear down faster than your rear pads. Most vehicle manufacturers recommend rotating your tires every 5000 to 7500 miles. This is why your front brakes wear faster than the rear. This is done in order to provide more stopping torque when the brakes are applied. So you generally brake more when you are turning .

Front brake pads will wear out much faster than rear brakes pads on a properly functioning and normally driven vehicle, this happens because front brakes do most of the work when slowing down. Mine wore out the rears faster. The proportioning valve that normally reduces hydraulic pressure to the rear brakes has been eliminated so the rear brakes will handle a higher percentage of the brake load and be more aggressive.

Just had the 150 go through the Quick Lane at a dealer I've used downstate many times, and the report came back that the rear brakes were worn down to the caution area. All four brake pads were installed at the same time and the rears have about 30% left on them while the front has about 75% left after 50k miles.
