I hope this guy put the EPB in Maintenance Mode as he didn’t mention it in the entire video!nice video, looks like it's a widely spread issue
There is an TSB with the rear brakes grinding, due to the rear brake pads not having the capability to remove the rust from the rear brake discs on CX-3,CX-5,CX-9 and Mazda6, although you mention yours is in the front, so this might not apply, but good to check.
The grease all over the rotor and brake pads was making me crazy. Even used the coated rotors that aren't oiled. I wasn't even going to say anything about putting anti seize on the lug studs. Also too much torque on the Caliper bracket and caliper bolts. Using the breaker bar and leaning on it.and another one, this issue is becoming viral
I can understand why the guy was putting grease and anti-seize compound all over, considering all the rust I can see on a fairly new gen-2 CX-5!The grease all over the rotor and brake pads was making me crazy.

And there’s a brand new TSB 04-007/20 which covers all CX-5’s from 2016 MY to 2020 with EPB.
Click the upper arrow next to the poster name Hawke at the beginning of his post which I enclosed in my post, it’ll take you to his original post with his TSB document attached. Yes the TSB does list the part number for new harder rear disk pads, although the original pads seem still available for sale. I believe this’s only the problem on OEM disk pads, at least for rear, for those areas with rust problem due to road salt.Does it mention new part number for the brake pads?
Was it an issue with Mazda pads or all compatible pads?
If it's with all compatible pads, are they going to be updated as well?

They probably don't use road salt in Japan.and just found this one https://repairpal.com/premature-rear-brake-failliure-705
and wow from comments it looks like this issue is at least seven or eight years old and nothing has been done, dealers happily continue to make money replacing rotors and pads on mostly unsuspecting customers
but brakes are essential for safety, all that is no good
This is all too common on youtube.I hope this guy put the EPB in Maintenance Mode as he didn’t mention it in the entire video!
You need a pair of new rear disk calipers based on the wear condition of inner and outer pads. In addition to uneven wear you’ll keep getting between inner and outer pads, you’ll also have possibility of rear disk locked up while you’re driving on the highway. See the 2nd scenario of pad condition in the TSB:This is what I took out

This is my first ever experience taking brake pads out, so I'm really interested in understanding if a) this wear on 13k pads and b) inside pads wear 3x vs outer ones is an indication of a defect or it might be normal? Common sense tells me it's not normal, what could explain that?
And please don't repeat the crap my dealer keeps giving me, I'm really fed up with things like:
- vehicle is not driven "enough" and rust eats the brakes (there's no such thing as enough driving, and how come front brakes are immune to rust)
- you live in the city - local driving means extra wear (I keep car just to go out of town)
- SUVs brake with read more to avoid nose dive (I believe that's total ***)
- rear pads extra wear is normal for AWD
- rear pads are thinner vs front pads - that's obviously not true
I put 400mi this weekend on my new pads without issue, a great endorsement of my pads replacement skills.
Thanks for the conclusionYou need a pair of new rear disk calipers
If you’re not going to keep the car for long, yes “you” don’t need these calipers.Thanks for the conclusion
Ironically *I* don't need anything as I was planning to replace the car back in summer, I'm just stuck waiting for Mazda to produce / install the recalled failed headlight unit.
I will do due diligence complaining about this issue everywhere I can to potentially save the future owner's live
In my experience, rust on the disc is worst, sticking calipers next, and not keeping your foot off the brake pedal is next. (I'm an amateur, not a mechanic).Funny how this issue resurfaces
I just had to replace all pads at 15k mi on another CX5, this time '21
Is there something wrong with the way I'm driving? Or the area I'm driving in? Or the dealer?
