Hi eveyone. You might have seen my post already. Since we talked about rear brakes, I decided to copy post here too.
So mine is mostly highway. So it might be the same. The back set is looks 30% smaller. There are a few articles on why suv rear wear out faster.
Tossing my data in cx 9 2016 at 105k. 80% highway drive. From 2019 to 2022 I added 70k miles. I also own a cx 5 2014. Purchased the cx 9 GT 2016 in 2019 used with 28k miles and possibly zero oil change...
First set of OEM Front lasted to 51k, I replaced it a bit early. Since I already removed everything and brake was cheap. I was lazy and left the rear for another day.
At 76k usage I replaced the back set, it was about time. Wagner OEX
The the good at 105k, (52k usage) front look amazing. I don't have a those tools to measure.. But I use two of those 1 gallon paint sticks. That gives you an good idea on how new it is. I'll show you the same on my unused one.
Back looks horrible, I heard some sounds and decided to remove / add new brake grease. It was worn down at 28k usage...
I had a lot of rust dust / brake dust. It clogged piston a bit ( I had to tear it because I over extended it...).
I attach a few pictures.
1) Current Front Wagner OEX at 52k usage
2) picture of new front unused Raybestos eht1258H with the paint stick
3) New rear raybestos eht1934H
4) Old rear Wagner 28k miles
5) The build up of the dust powdered on the pad
PS) My rear Wagner for Cx 5 didn't last as long to. I think about 35k and was metal (6) main issue was the brake caliper not releasing and destroy my break rotor and pad. There was a bit of life on it. Maybe 5-7k more. If everything had no issues. But it 100% wear out faster then OEM
Ty for all those mazda user that spend time post and document
