Leehoewonek I just had my 2018 (only 39500 km) in for a brake service and I'm in the same boat you were in where they are recommending all discs and pads be replaced. Did you have to contact Honda Canada directly for them to cover it or was that done through the dealer? Just trying to find out how to approach this. Thank you.
Thank you for the reply and information. It is really appreciated! Going to contact Honda Canada next week and see how it goes.
I used a wire wheel on a drill and some wire brushes to clean the brackets and caliper the best I can. I put the brackets in a vice to do this. I didn't remove the calipers from the car. That would be ideal but that is a lot more work since it would require bleeding the brake lines. I do the best I can cleaning them and then tape off what I don't want to get paint on. I then clean them using brake cleaner and blow it off with compressed air. It would be best to then use sand paper and clean with mineral spirits or another type of degreaser but I am not looking for perfection. I do use brake caliper specific spray paint. I will post a pic of the can I used when I get home.
Every Honda/Acura I have ever owned has had issues with warping rotors. I believe I am the reason.
Aggressive driving is usually the cause. The Clarity is a heavy car so I am not surprised the rotors warp easily. Honda should have used a larger rotor that could better handle the heat without warping. Luckily replacing the rotors on the Clarity is not too difficult and aftermarket rotors are inexpensive.Temu brake rotors from the factory is the reason. Honda tossed the crappiest iron money could buy into those rotors (probably straight up pig iron, knowing how Honda builds things these days).Every Honda/Acura I have ever owned has had issues with warping rotors. I believe I am the reason.
I have replaced my stock front rotors with Powerstop JBR1766EVC and then with Raybestos "high carbon" 982358. Both from rockauto.com. I also recently cut the Raybestos after replacing a frozen front caliper that caused the rotor to warp. They are starting to vibrate again now. I currently have over 143k miles on my Clarity. I am debating what brand rotors to try next. I will probably go with the Raybestos "high carbon" again. I have considered getting a slotted and drilled rotor but I have seen them crack before. Plus you can't cut them if they warp.
I haven't experienced rotor warping, but those OEM rotors rust more than any I've ever seen. Do the "high-carbon" Raybestos rotors rust?
Honestly, best choose would be some ceramic pads with grooved/slotted rotors (not just ventilated).
99.9% chance they do, probably not as bad as the stock rotors though. With brake rotors unless you get some really specialisty ones they are basically going to be made out of cast iron (high carbon iron basically, for some reason iron+some carbon (and other stuff typically)=steel, iron+even more carbon=cast iron?!), anyways, stainless steel rotors basically don't exist outside of a select market.
I don't have my car today. When I do I will take a pic of the rotors.
My experience with the rusty rotors doesn't require photos. If you can't hear the rust, your Clarity's brakes are fine IMO.
Do you feel the throbbing and hear the rubbing sound even when not decelerating? Did the throbbing happen when using the brake pedal and/or when slowing with only regen?
There is no way to "recalibrate" Regen. The only functions you could even call related would be brake pedal zero position relearn, and traction motor position sensor retraining. TBH I'm kinda surprised that there isn't a "friction brake" relearn for when you replace the brake pads, dunno how it could work, but as far as I can tell the clarity just uses some programmed friction/pressure curve/table. But even if such a function did exist it wouldn't change the fact that the rotors are warped/acting funny.
