Well, you SHOULD use it occasionally, or someday when you need it it won't work!

And notice the OTHER common culprit, a mechanical issue causing it to drag....

BOTH are more common than defective pads or rotors.... Not that it COULDN'T happen, I just haven't seen a case yet....

Luck!



( I always like to hear a reason for a failure, even if it's fixed under warranty...)

P.S. - The last time I saw a REAR brake that someone wanted warrantied, it was on a Motorcycle. And the owner wore out both the rear tire AND the rear brake (pads & rotor) by the time he brought it back for it's 600 mile check up! You can probably guess how THAT happened... (grin)

(Thought you could use a chuckle...)

And if the Dealer needed to order parts, they found SOMETHING wrong....

I have what I'd call extreme rotor wear, even though the kids drive slowly, and I'm light on brakes (2012 SE with Sport Pkg). Before the 1st oil change (about 4,000 miles) I noticed significant groves on each rotor. I tried to rebed the brakes, and things looked better. I mentioned it to the dealer a short while later, and we agreed that things looked ok. The grooves continue to appear, but I regularly rebed and when changing between snow tires and summer rubber, I use garnet sandpaper on the outside, which also helps (I use garnet sandpaper on my Acura twice a year, too, to remove deposits which give that pulsing brake pedal, but the Acura's rotors have never looked like the Focus'.)

The rears seem to show greater wear, and my bedding the rears involves driving backwards and several hard stops; the autotrans/computer seems to limit how fast I can drive in reverse.

Still, after 20,000 miles, the brakes still work great. But I was actually found this thread while researching replacements, for when it's time for a change...and while that may be in a while, I will continue to watch my rotors, rebed, and sand twice a year.

unfortunately i seem to have the same problem. my 2012 focus has a rear brakes issue. after getting my summer tires put on, the dealer said i needed a complete rear brake job (pads and rotors). i found that odd that i needed to replace the rears yet the fronts are still good. i asked the the technician if there was a mechanical issue or something because i never had to replace rears before fronts before in any vehicle i owned. he said no that everything looks good just that the pads/rotors are worn out and grooved badly. most of my driving is highway and i really don't understand why this is and feel this should be a waranty issue considering its the original parts. i tried to call customer service but they don't know anything and said they cant do anything

Have seen a few reporting more "grooving" than they feel is normal, that tends to result from more aggressive pad materials that give better braking performance, particularly in the wet.

The only contributing mechanical issue I've seen reported is rear wheel bearings, noise when not braking is the identifying symptom most often noted.

Grooving per se isn't an issue, pads & rotors are more often replaced as a set these days - for this reason.

Rear pads & rotors have less material than the fronts, "normal" braking wears fronts much faster than the rears & the idea is to even out wear at each end.

Not a large number of posts commenting on brake wear, more with rear wearing first but I've seen a couple reporting front wear they weren't happy with. Hwy. use & light braking might factor into the rears wearing faster. Wonder both how worn the pads really were (vs. replaced for "grooving") and how many miles you got before replacement was recommended.

Can't second guess at a distance, in a few cases replacement was "sold" by pointing out grooving before pads were worn enough to require it. Could just as easily have been "due" for replacement.

Recommendations usually err on the side of caution, anything likely to need service before the next oil change service is recommended - and with that interval stretching up to a possible 10,000 miles on the current cars "half worn" is often the standard.

P.S. - saw a post today from an owner with a Manual trans., 104,000 on the original brakes. As they say, "your results may vary".

Just an update... Now with 35,000 miles and 3 yrs of use, the original "oddly wearing" brakes are still working great. Every once in a while I get to drive the car, and occasionally go through a bit of a rebedding process.
