2017~2022 Just Awful Brake Life

At 18,300 miles I now have had to replace brake pads on all four wheels ...again. The rotors are now scarred and must be turned or replaced. This following repacement of all brake pads at about 8,700.miles. I have stated in previous posts that I cover about four kilometers (2.5 miles) daily over unpaved road. When it rains there are many muddy potholes. As well my daily journey consists of about a ten kilometer (6.3 mile ) decent down a mountain road so a fair amount of brake use. The dealer said the occasionally muddy road section is probably the cause of the scratched rotors. OK fair enough, however...I have driven this same commute for fifteen years with several different vehicles with hugely different results. My 2008 Nissan Frontier required new front pads at 40,000 kilometers (25,000 miles). My 2014 Renault Duster required new front pads at 60,000 kilometers (37,000 miles) and new rotors at 79,000k (50,000 miles).

I'm dumbstruck by the poor service life of the brake system on this car. It is a great car in so many ways but I've come to realize it is a car for paved (and preferably flat) road travel only.

This is with Mazda OEM brake pads right? Have you tried other brands of brake pads?

The brakes, overall, even the upsized ones on the turbo models are pretty marginal at best. Combine that with the way manufacturers now seem to have multiple traction and driving aid systems using the brakes way too much and it's no surprise pad and rotor life is getting pretty abysmal for anything but highway driving. I'm guessing that not just your downhill use of the brakes, but the off road driving and the associated use of brakes by the computer systems to compensate for the rather weak AWD system is causing a lot of wear.

Do brake pads in your country have a lifetime warranty (covers parts cost, not labor) like in the US?
Also, tell them you want premium Mazda pads and not the 'value line' pads that are made in Mexico

Thank you all for the suggestions. No I haven't tried other brands but I doubt a better quality pad is available here in Colombia. No warrenties on them that I know of. Zoom that's a very useful explanation and confirms what the service manager told me. He said there were four different systems used on the vehicle explaining uneven pad wear.

Can you get other pads imported? Would be more expensive to import I imagine, but maybe over the long run it would end up being the cheaper option (if they last longer than the OEM pads). If anything, I would try out the premium Mazda pads as @dunhillmc suggested. Hopefully you haven't changed the pads out yet.

Most modern cars with improved safety systems utilize the brakes in similar ways. What's happening in your car is likely what would happen in any comparable car in the same class, though Mazda's AWD has been proven to be as good, or sometimes better, than most of the competition. There is likely a better performing AWD option out there, maybe one that doesn't exhibit the brake life issues you're currently having, but there will be tradeoffs in making the switch.

In any case, you may be able to mitigate the problem with different pads, so that's where I'd start.

I know that Raybestos made commercial grade pads for delivery vehicles (trucks,vans) that had a harder ,long wearing formulation for severe applications. Probably why UPS trucks etc. had squealing brakes. Don't know if they are offered (by any brand) for passenger vehicles and if so, one would want possibly noisy brakes or possibly have to apply more brake force.

Wish I could help more. Good luck.
