Rear brake disc
« on: June 06, 2019, 12:07:28 am »
Well on another thread I posted about some decomposing EBC brake pads. EBC has been wonderful and replaced them free of charge promptly just like people here said. Go EBC. Now I am wondering whether my rear disc is good. I called and was told the bike has had the rear brake recall done, but I have no way to know if at that time they did anything to the rear disc. In any case, the bike has 30,000 miles and when I rotate the rear wheel in neutral, it seems to drag in one spot as though the disc isn't true. It also has some slight discoloring in patterns that make ti look like it is somewhat warped in that there are spots that are dark from carbon and spots that are light, as though it is wavy.

Your thoughts? I'm inclined to replace just from age though can't say if 30K is sufficient time to replace generally.

By rear disc are you referring to the rotor or the pads? I assume you're meaning the rotor. I'm at 57K miles on my C-14 and my rotors are good / true on front and rear. I understand the need for replacement of the rotors can be dependent on your driving style and the type of brake pads used... for what it's worth. There are others on this forum who are knowledgeable than I in such things.

All my 4 Kawasaki's have a spot on the rear disk that seems to drag when spinning in a certain spot. I call it normal.

Yes, disc is rotor is disc. Seems to me that if my rear is rubbing only in one spot as I rotate the rear wheel then clearly something is off.

The creation of this second discussion, leaves everyone in the dark about the original discussion, and creates the need for jumping all over, to get the complete story... in the future, if you start a thread, please keep the other input in that same thread, so duplicate responses can be minimalized.. thanks in advance,

Fair point, MOB, I hesitated myself. I guess we either muddle one discussion with many partially related topics, or start multiples that require browsing.
