Sure I could upgrade the pads, but if he's living on the brakes, it's the rotor that is taking the heat. So, what do you do? Replace it ever 2000 miles? I guess that might be the only thing I can do until I figure out a Galfer option perhaps. Something that can take extreme braking and last. I truly think the weakest link in all of this is the rotor.
Every bike I've had never had upgraded double H pads in it. OEM is standard pads....not very different from the stock ones on the RX3. So, really that aside, what's left? The caliper, no matter the price should work just fine. It is a simple mechanical part. The rotor must be the issue. Now that I think of it....perhaps the rotor was warped this whole time? Maybe it was never a "good" rotor. Do you know how many times I've bought rotors for my cars from PepBoys and I've had to have them reshaved due to them not being manufactured properly. IDK...I'm just thinking out loud here. It's making me  |
Agreed....but I've also read here that some of the early bikes had bad rotors and once swapped out, seemed fine. I've read about retorquing, etc... Who knows?
Like jb, Jay and others have said, under normal braking, it seems ok. It's just when I get it good and hot, like on a very long downhill or getting real aggressive, does it act up. Then it goes away. Like I stated earlier, it's not the braking power, it's the changing attitude that makes it unsettling.
Your Pep Boys car rotors. I was a mechanic for quite a number of years. There's no such thing as a flat rotor. Even on the ones that showed no wiggle out of box, they're warped if you put a mic against them....just not enough to show thanks to a floating caliper.
We turned every rotor out-of-box prior to installation to completely eliminate come-backs. Also, we discovered that the warp is caused from shipping. The further down the pallet the rotor came from, the more weight was on it and the more warp.
