At about 25,000 miles I had one of my rear brake pads sticking so had to change the rear brakes. The non-stuck pads on the other side looked decent still, so I'm assuming I'd have gotten quite a few more miles out of them if the one hadn't been sticking. Changed the front pads at about the same time, although they were in pretty good shape still (but it was taken apart already, so did them while it was apart and the chance was there). At about 50,000 miles later the rear pads are again unevenly (and I feel perhaps prematurely?) worn, and the fronts look fine. Does anybody else notice this happening to them? Is it something with the screw-type e-brake mechanism on the rear disc brake that lends itself to sticking? Or am I just especially unfortunate?

On my 2010 AWD XR with 60,000 km/37,000 miles I'm still on my original pads.
They have been inspected and lubed regularly by my dealer and are nowhere needing replacement yet.

Simply based on my experience, I would say that more regular inspection and lube might have prevented your issue, but then, some cars just have unique problems that others never have.

I changed my rear discs and pads at about 60k km [37k miles] because one side was stuck. Now I'm at about 135k km [84k miles] and I they are worn out again. The front discs and pads are OK and I never changed them but I will probably have to change them soon.

I'm doing lube regulary.

If I may ask, how often is regularly for you? I've considered starting to do that to help prevent the sticking, but wasn't sure if that would resolve the issue or not.

 

[P-P]

Every 32k km, as per the owner manual.

Interesting. My scheduled maintenance guide just says to visually inspect brake linings/drums and brake pads/discs every 5000 miles, says nothing about cleaning/lubricating, so as far as I know it hasn't been getting done.

It's weird

Do not see "Brake Service" anywhere? (at about every 32k km / 20k miles).

I took this information from the Canadian Owner manual.....

 

[citrustwist]

Nope. I checked in the owner's manual today, since I didn't see it in the scheduled maintenance booklet, nothing there either. Maybe since they build the cars in canada, they want the ones sold in the US to wear out quicker so we have to buy new ones

Citrustwist,

No, I think that it is simply how local dealerships interpret the service requirements for certain vehicles, and the techs just try to save themselves some trouble.

Case in Point:

I've had two Mazdas in the family for which the service requirements specifically state to inspect and lube (as required) the Manual Transmission Linkage (626 and 323). Since this linkage is under the car, sealed in a rubber bellows boot and requires some disassembly, it is rarely done by Mazda Techs. On both cars the transmission became increasingly difficult to shift. It takes about a half hour to totally disassemble, grind off any rust and relube the components to get the linkage buttery smooth again (a process I am now personally very familiar with!).

I agree with the above. I've seen the same thing on my car, the sliding pins dry up within a year. The lithium soap glycol grease that toyota uses, is only good for about a year. I think there was a thread here what part number that was. Using silicone lube is ok, but the problem I've seen is it gets gummy and stops lubing within a couple months. The toyota stuff is better. about $13-18 a tube. So yes, every 15,000 miles or once a year lube them up, cheaper than a new caliper!

Hmm.

There the official maintenance schedule for my car. Always says visual inspection of brakes. Nothing about lubrication. I think I'm just gonna start doing it anyway, because I'm sick of buying new brakes and rotors. I guess I'll find out if it helps in another 25,000 miles.
