It may sound mundane, but in 5 years and 70k miles it’s the first real work we’ve done on the Odyssey. Boring, but reliable. It’s growing on me.

Akebono pads and Centric rotors, favorites among the Hondascenti.

Old rotor was ok, but I prefer to change them with the pads, especially after several years.

New vs old pads. We had about 20% left but some of them were wearing unevenly. The protrusion is a low-tech noisemaker.

Freshly milled, complete with black powder coated hat! (Which also serves as a drum for the parking brake inside.)

Oh, for a Honda I would call the rotors just broken in!

LOL, I took my caliper to them and they were still well above minimum thickness.  But they were nearly seized to the hub (NO road salt here) and I already had the nicer rotors in hand, so...

Look at you, doing your preventative maintenance like a good boy...while I flail about randomly cobbling together already broken shit whilst waiting for more worn out shit that I know we have to break.

I'm beginning to wonder if your way might be better

 I'm glad you had some help.

Ah, you must be referring to our other car! Mine. The one that carries the kids gets the attention here.

The Lad is getting quite used to being in vehicles that either have something broken about them or simply break along the way...

Good work. There simply isn’t a good reason not to change rotors with pads these days. 20 years ago Rotors were still expensive enough to reuse, or have turned and reused, but even high quality rotors are so cheap for most applications today.

you put the retaining screw back in! confidence level = expert

good work training the next generation of oppos

Centric are good rotors, I have used them for years on our race cars. Grooves have never bothered me and I don’t see them as a justification for replacing rotors. If they are not warped, why replace them with a set that might warp. My ‘07 Civic SI has original rotors all around. Sure there are grooves, but they don’t pull or pulse si I haven’t replaced them. I did replace them on my ‘07 uplander because GM uses lesser steel and they were getting mighty crusty here in rust country .....

To be clear, I didn’t replace them because of the grooves, just as cheap insurance. The last thing I want to worry about is getting into a “leapfrog” replacement cycle of pads and rotors, basically doubling my labor.

For all the years I learned DIY on VW and MB, I was always used to their rotors wearing out at the same pace as the pads (by design). It was interesting to see these had only lost about 10% of their thickness — rough estimate from my caliper tool.

Even with no road salt, the amount of rust around the hub was already  the worst I had ever seen in this climate.

All true, I guess I am just sharing the pespective that id the rotors are not wearing, or rusting, or warping you can take the perspective that they can last the life of the vehicle. Honda rotors seem to hardly wear, my wife’s 2002 SI had original rotors at 200,00o miles when she sold it.

One thing though is I always used Honda pads. Maybe that is why the rotors last . Also she hardly u sed the brakes. Again, I don’t hate changing rotors, I just hate putting new ones on and having them warp when the originals did not. 

Also, the hub screws in my experience can be discarded without worry. The reason they are there is for plant assembly convenience. The wheel locks the rotor in place.

Totally agree with you — when it comes time to change the front, I’m also going to do rotors, but for a more practical reason...warping. The jury is still out on whether these Odyssey rotors truly warp or just get hot spots on them from standing on the brakes while hot. Either way, there was definitely some pulsing in the pedal at 20-50k miles, which seems to have mellowed a bit.

Plus the fronts have a bit of a lip on them, so I suspect they have been worn down a bit more than the rears (not surprising, we do 80%+ suburban/stop&go driving).

I’m hoping for lower dust with the new pads. That’s always been my experience on prior cars — t hat OE pads are great for stopping , but dirty.

Funfact: This is the first car I’ve owned (or done brakes on) with lug nuts , not lug bolts. On my prior VW/Audi cars and my in-laws’ Mercedes vehicles , the rotor, wheel, and hub had to be precariously lined up visually, each one rotating independently, so the lug bolts could be reinserted. On those cars, the hub screw was almost a necessity just to get the hub and rotor aligned and free up your hands to put the wheel back on . With traditional nuts, the fixed bolt really makes things easier by lining everything up for you. In addition, those cars all had parking brakes that worked via the rear caliper, so they required a special key to compress the piston. This was much, much simpler.
