Premature Rear brake pad wear

[johnnyrako]

I have a 2021 Yukon XL and I’m having orenayure brake pad wear. The fronts are 75% life remaining while the Rears are at ~ 25 % life remaining.
I’ve never had a vehicle wear more on the rears than the fronts.
BTW, Vehicle is mostly used dropping kids off at school..
TIA for your input

How many miles on the brakes? Most likely sticky calipers or light foot pressure on brake peddle while driving. I have 120K miles on my original brakes with 50% pad left front & rear on my 2018 Yukon Denali.

Suggest you really inspect the rear brake pad thickness rather than rely on the predicted life indication. While my 2024 Yukon is just at about 5000 miles, I did peak at the brake wear and it appeared that the rear value was decreasing slightly more than the front wear early on. Understand this is a "predicted" percentage, maybe the mileage algorithm they used for the rear brakes is incorrect. No idea if the algorithm can factor in towing as well somehow.

Just checked my brake life at approximately 5000 miles and both front and rear are listed as 97%, but as mentioned, the rear was leading the front earlier on which I thought was unusual. Will have to get more miles and will continue to monitor to see what happens with the rear percentage.

I’m aware of the rear disc brake pads wearing out before the front brake pads on two vehicles in my family purchased new: a 2015 Ford Expedition 4x4 and a 2017 Dodge Grand Caravan FWD (both use exclusively for passenger use).

After running on the highway a few miles...I stop and feel the hubs/rotors with fingers....(can be hot)....I can feel my RT rear rotor is very hot...all the others are slightly warm. This is telling me something....................dragging. I will fix.

If I use my hands, I use the back of my hand, far more sensitive to temperature. Even more sensitive is your face, but you better be careful! I will not touch any metal parts, just get the back of your hand or face close and you will feel the heat.

Best to use an IR thermometer if you have access to one.

I got the right rear caliper changed today. Pads were ok so reused 'em. The wheel turns freely now. That thing cost me almost $90 and it was a re-man. from Mexico. Guaranteed tho.

I have an IR thermometer, but too lazy to go get it. Just stick my finger thru the wheel onto the rotor. Depending on size of blister, I can figure how much dragging it's doing...ha ha

Modern brakes don't brake as simply as they used to.
The rears grab a microfraction of a second before the fronts to minimize brake dive,
and up to a point, squeeze harder than the fronts, up to about 17% braking.
Beyond that, the fronts increase their rate of squeeze.

By 33% braking, the brakes will wear the way your grandparents told you.
But under 17% braking demand, your rear brakes are working harder than the fronts.
