110k km and no brake replacement

[19ExpMaxPlatYYC]

I'm at 110k km and haven't replaced pads or rotors on my '19. Based on what I'm reading on this forum it's clearly time for the job. Yes...it still stops!

I'm baffled as to why some are wearing so quickly or mine lasting this long.

I see people doing pads only, some vehicles claim to be pads and rotors due to rotor wear. Do we know the service thickness for the rotors? Thickness when new?

I'm 99% sure that driving style explains the wear differences between vehicles for brakes. You and I obviously try to avoid hard stopping. Others seem to think big SUVs should handle exactly like sports cars and drive them as such.

I have a 2012 that I bought with 100k miles. It now has 180k and the only thing done brake-wise is the front rotors have been turned once. Still on the same brake pads I bought it with.

I think driving style has a lot to do with it. Just had mine in for service (that's another story) at 55,500 miles and I thought they'd get me for brakes, but I'm still good. Getting low, but might be good for another 20K. I'll be looking at tires pretty soon though. For the record, I don't tow or use adaptive cruise, which also wears on brakes.

That's 68k miles. Lots of things affect brake wear and there are lots of opinions on when to replace pads relative to thickness, etc.. I helped my neighbor replace his for the first time on his 2019 MAX at 81k miles (130k km). At that time, he had less than 1/16" (1.5 mm) of pad left on the rear pads and 1/4" (6.4mm) left on the front. My '20 is probably wearing very similar to his. At 45k miles, I estimate that the rears will be down to 3/16" (4.7 mm) by 55K - 60K mi (~92k km), at which time I'll replace them. The fronts may go as far as 90K miles (145k km) + before they are down to 3/16" (4.7 mm) if they continue to wear the same. I don't have any issue with warping, nor did my neighbor. I'll probably have the rotors turned if they're within service thickness and still flat.

One thing to be aware of: My neighbor and I live in NC and our vehicles are garaged. None-the-less, all 4 rotors were mildly corroded onto the hubs of both of our vehicles (I checked and freed mine without doing the brakes at the next tire rotation). I'm thinking you might have an even worse situation in Alberta. Be prepared with the proper solvents and tools to free the rotors and buy some good nickel anti-seize before doing the job.

If you haven't already replaced shocks, check for leakage. If you've done any off-roading, I would personally be shocked (yes, I went there) if the rears aren't leaking. Many on this forum did as I did and replaced them with Bilstein 5100's.

Also, where you live plays a lot into it. I live in the Dallas area, and we hop on Interstates or highways to go just about anywhere. You can easily drive 20 miles without ever touching your brakes. When I lived in Cleveland, I'd only get on the highways for a few miles, but I had several miles to get to them or anywhere and it was all stop signs and stop lights. It's much easier to put more miles on your vehicles here with little brake wear compared to Cleveland.

Thanks for the replies, good to know others are getting there. Too...sleeping children also helps keep you from getting onto the pedal too hard.

Wait, what?

You mean my Expy isn’t just a bigger version of my old Corvette??? ️

Hmmm, I guess that means I’ll be changing the brakes at 20k miles…

Well, made it 114k km before a rear right pad expired and ruined the disk. One front and one rear may have been able to be turned but that's a bit of a pain when you're out of town and need the vehicle on the road.

Front left wore strangely...very strange. Pad was worn on the outer edges and only making contact in a narrow band in the middle. I did get a sense it was wearing funny but it was pretty subtle under braking. Perhaps the right rear wearing faster is related.

Here's a pic, the pins were sliding properly, I can only assume they were stuck at some point early on.

Any thoughts on this wear pattern?

Dealer was $710 cdn per axle with new rotors, $510 if they could be turned. Parts for ceramic pads and corrosion resistant rotors on both axles were about $430 plus $170 shipping.

Gotta love Rock Auto.

I hope that extra 4,000km was worth the pain.

Driving style is key to brake life. I had over 150K miles on my 2017 expy I traded in for my 2023. Mostly interstate miles but also many offroad miles in rough mountainous travel doing geologic work. I try to use engine compression for braking going downhill and slowing down in traffic. Still had over 40% brake life when it was traded in.

The right front was probably still at 65-70%, but the front left was a mess...

Brakes....pads.... rotors.... what dem iz ?

Seriously though, my 011 Expy has about 120K miles on it & when I got it inspected last week, my mechanic said it would need brakes & maybe rotors too.... IN ABOUT 6 months...

But as a side note, I drive it exactly like I drive my Shelby GT 350 (or a good woman) fast, hard, & all day/night long....hehehe

Not sure what the conversion from km to mi is but the brakes on my 2020 didn't require a change until almost 118k.

Just replaced my rears at 50k miles. Almost gone, small amount of friction material. The discs show slightly higher than normal corrosion and irregular wear on the inner sides. Replaced discs and pads for $250 (Powerstop). I have a slight vibration while braking from the front, but the pads there appear to have a lot of life left. I'll be replacing them, both pads and rotors, before long.

Honestly, if there's even a hint of any issue with the rotors, I don't know why you wouldn't just replace them at the same time.

 

[Bmac1955]

If brakes are monitored for wear and time to replace at about 3 mil left no pulsating or scored, why not just have the rotors turned. Save yourself some money. Just my opinion.
