Rear brakes should wear LONG after the fronts, and shouldn't be an issue until at least 50k miles. Typically.

The exception to this would be hard track driving without disabling the rear torque vectoring. That will kill your rear brakes very quickly.
this is a bit misleading albeit unintentionally.

I wouldnā€™t count on people doing the pedal dance as commonplace.

The typical use case is more likely spirited driving with traction control fully on, and so RIP rear brakes, and way sooner than the front.

On that note, my rear pads were gone at 25k miles and the fronts were doing okay, about ā…“ life left.

Are you talking about rotors?

Because the rear pads are known to have a short life in this platform. Doesn't matter if you track it or no.

I'm not aware of any type of "spirited driving" that should wear the rear brakes/rotors at an accelerated rate, pedal dance or not... at least not within 10k miles. There is a HUGE difference between any type of street driving, and track driving.

Unless they're Fujiwara Takumi delivering tofu or some shit.

However...

Yeah maybe I'm just missing something, and honestly could just be out of touch so I'll defer any further comments. But I will ask for data points. @dockleryxk provided his own above, saying his rears were done at 25k but the fronts were fine. Is this "common to this platform", or is this more related to the aforementioned spirited driving with the traction control on; i.e., brake vectoring?

I honestly haven't owned a car long enough to wear through a set of brake pads, front or rear, in about 15 years. So I'll shut up now.

You were pretty close ā€“ brake vectoring is a huge part of it. I drive my car hard, and I was not surprised that I wore through my tires at < 15k miles and my rear brake pads in about 25k miles

Main takeaways:
  • is it weird that the rear pads are wearing out that fast? Not necessarily
  • is it weird that the rear rotors were toast? yes, but it would make sense that the bad rotors messed up the pads (or vice versa). I'd want to know what caused the original issue
  • @NBE1_S7 ā€“ get a second opinion on the rear pads and rotors ā€“ there is nothing special about working on them for a shop. They can take a look and tell you quickly.

It was common on the V6 6-speed Accord. From general consensus on the forums, and I also experienced it when I owned that car.

Though, fronts should always wear faster if you have rear drums!

Funny i stumbled upon this thread today. I was just at the dealer yesterday for a screw removal in rear tire. I had all 4 tires rotated and Iā€™m at 11600 miles roughly. One of the sr techs there pointed out my rear pads are running a little thin. Recommended to get new rear pads in next few 1000 miles so I will do so. Along w tires most likely. Iā€™m uncertain on having the rear rotors resurfaced at that time. I get mixed opinions at the dealership.
I'm surprised they mentioned tires as well. I'm assuming you have the stock PS4S still right? 12k miles for those seems extreme but obviously I don't know your use case.

Well I had them rotate the tires. Now I have more rubber up front & the rear a lot less. So I plan to do it a bit early. Itā€™s a daily driver really. Stock tires yes & will prob go w the same ones unless I opt for an all season tire ? Iā€™m guessing between rear pads, resurface rear rotors. Tires by Early January I would need to drop $2500 Iā€™m guessing

Yeah, I don't know what world you're living in, but brakes and tires for a car with ~12k miles is insane.

FWIW, I am extremely hard on my tires with about a dozen autocross events and most of a full track day on them, and they're fine from a treadwear perspective at almost 9k miles. I can measure them tomorrow, but my guess is they still have at least 5/32 left. But the shoulders are toast. Without the track duty, I have indeed gotten a set of PS4S well over 15k miles personally- and I'd expect around 20k out of them honestly. Minimum.

The only exception was on a 911. The 305s in the rear had almost no tread depth on the inside of the tire and were replaced around 13k miles. Apparently that's normal for that car, just a side effect of the effectively unique suspension geometry to keep all that weight in the rear from sliding around every corner. But this is not a 911. I'll be irate if I need to swap PS4S out every 11k miles on this car.

As for brakes, I'm still scratching my head from the responses in here. Maybe my expectations are just wrong, but no way I would expect new brakes, front or rear, before AT LEAST 20k miles.

have you tried bedding in the brakes? sometimes they just need a few hard stops to get smooth again. try braking hard in reverse a few times.

Get like me bro this was at ~12k miles

For real though, are you that hard on tires? Because if so, youā€™ve got about 3k miles left.

Thereā€™s a guy local to me that changes the front tires on his FK8 every 5k miles. Thatā€™s crazy, but equally as crazy as expecting over 20k miles from the OE tires if youā€™re driving them hard at all.

So your saying the rear brakes should last 100k miles?

Not sure about the reverse method but I would generally agree and look into this first. Unless Honda brake rotors are made of some unusually weak ass material, I am of the camp that its actually extremely difficult to warp rotors and if you're feeling vibration its due to pad deposit that just needs rebedding of the pads.

If this was a dealer recommending this, mmm I'd be suspicious of that dealership. Reminds me of this clip (begin at 12:47 mark)

I am on my 4th set of pads in the rear. Just crossed over 40k miles. First three set were OEM pads, OEM pads SUCK. Each set basically lasted 10k. My OEM front pads lasted about 25k, switched to Paragon P3 and Paragon rotors since they were lipped. Stock rotors in the rear currently but running EBC Yellow (would have got paragon p3 but needed them urgently.) I frequently autoX, carve backroads and do a track day every once in a while.

So there's still a chance šŸ˜‚
I replaced my rear pads when I upgraded to Paragon rotors at 18k.. rears were about done.
