Warped rotors?

[dave]

Just thought I would throw this out there: Did the warped brake rotor condition become obvious shortly after having a new front tire replaced? It's possible the mechanic installing the new tire accidently damaged the rotor. My CB1100 has not exhibited any bent brake rotor conditions, but I replaced two front brake rotors due to warpage on my 1998 VFR800 within 80,000 miles - the first occurring at about 35,000 miles.

Pretty sure my old CB had a pitted front rotor. Definitely had pulsing. Could hitting a giant pothole do it...?

If you hit a pot hole deep enough to bend a rotor, you would know it. YOu wouldn't have any teeth left and your spine would be permanantly jammed lol.

Changing the tire with the rotors on does require some care. I had to create a jig of sorts to make sure I wasn't putting any pressure on them while changing the tire.

first thing you might want to do is clean the pad retaining pins! and I mean with sand paper too, not just brake cleaner alone. cleaning those boys alone can make brakes feel brand new.

Sounds like it could be a number of things. I'll probably end up taking it to the shop to see what they say. Thanks all.

I went through 3 sets. First under warranty, second off the salvage CB that I bought, the third off eBay. If one rides hard, they're going to warp. If one rides like the bike is intended (owned and operated by old, fat, bald, white guys) they'll do just fine. Never do a track day or ride hard thru the Dragon or the like. Happy 4th !!!

My old Ktm1190adv suffered pulsing brakes . It was brake pad deposits caused allegedly by coming to a stop with hot brakes and not moving off or keeping the brake on so the pad and disk remain in contact whilst still hot and not getting cooled. The result was a visible copper coloured pad shaped deposit on the disks. This proved difficult to remove without skimming ( so new disk were used to cure it)

This is something I watch out for any time I've done any hard braking. At a stop, I'll release the brakes and roll the bike a foot or so to keep the hot pad from causing a hot spot on the rotor.
