I just read this. In 25+ years of mountain biking, I have never heard of anyone needing to replace a worn disc. Is that really a thing?
I have worn through multiple discs. While I can't say the braking performance was bad, they certainly were under the limit when measured and visually were really thin where the pad contacts.I just read this.

Was that with alloy rotors or steel? Or both?I have worn through multiple discs. While I can't say the braking performance was bad, they certainly were under the limit when measured and visually were really thin where the pad contacts.
I don't like a lot of free-throw before the pad contacts the rotor and new rotors definitely helped with that especially as the pads wear.
Do Alloy rotors exist?Was that with alloy rotors or steel? Or both?
I guess I don't ride in enough wet and muddy conditions.Do Alloy rotors exist?
Steel, and none of them were organic-pad-only rotors as I gave those away whenever I ended up with them. I can't recall specially which they were but would have been the normal Avid/Shimano mid-range ones.
I just assumed it was from wet/muddy conditions.
not sure why he has you adding water, water does NOT increase the speed at which the pads wear in, all it will do is carry the dust away (maybe).

I'd be shocked if that were true. All I've ever heard was that wet = faster wear. True in my real world experience as well. I'd love to be wrong if you have any sources that disagree...google is coming up empty.
Absolutely lol. Over a long enough time period the rotor wears down under their recommended thickness which is usually posted on the rotor. I'd take a caliper to yours, you'll be surprised.
I put new brake pads in at the trail head and bed them in on the first descent.
I've replaced rotors due to wear on several occasions. They don't look worn, but if you hold new rotors up to them, they are laughably thinner.
Like, did you actually laugh?
I wet a paper towel with alcohol and rub the rotors clean. I then take fine sandpaper and scrub the rotors in both directions, wipe the grit off with the paper towel, and install the pads. I’ll ride around my house as well as up and down the driveway a few times and the pads are bedded (is that a word?). I’ve never had a problem doing this.
For shits and giggles, I inspected my rotors today and could not see any noticeable wear. Maybe the next time I take it to the shop the mechanics will see something different. But they won’t. Because in the bazillion times I’ve taken my bike to the shop, I have never been told I have worn rotors.
Also, my new pads are no longer rubbing. I must have worn down the rotors. 😂
Wait-so you’ll change your bike rotors multiple times but the car…In Jim's defense, he put new brakes on his Honda Fit at 90k. Mine has 96k on the brakes and the tires the car came with are still on it.
