Hey guys.
So after upgrading my pads (EBC HH) and brake lines (goodridge braided steel) it seems my rotors have warped. (rotors had 24k kms/ 15k miles on them)
First question is what is people's experience with this? are the K9-11notorious for warping rotors? reason I ask is that Australia is largely out of stock on (decent) replacement rotors making me wonder how much this happens. Also a mechanic I spoke to said he sees this a lot in the modern sportsbikes with powerful brakes and otherwise minimalist rotors to save rotating weight.
Second question is, what experiences and reccomendations do people have a potential replacement rotors? (OEM and BREMBO out of the price range). Ive used MetalGear before and impressed but they are out of stock until February!
in my past experiences. i have gone with EBC high performance brake pads....with time the brake pads dont wear out fast...but your rotors do. with time they tend to warp making them useless.
again this is from my past experiences. it is better to go with brake pads that are soft on your rotors but with good stopping power.
if you ride on the track...you want high performance.
ok cheers. Ill keep that in mind.
Been happy with EBC's over many bikes though and I like the feel of them. Not had a case of warped rotors before either...
any other feedback on the rotors etc and some replacements?
well between the decent quality price rotors being out of stock for a long time and otherwise OEM and Brembo just being silly money im going to go for a set of the generic replacement wavy rotors.
They are located in Australia (so next day delivery so I can get the problem solved) and with a 24 month warranty it means that if they aren't up to the task then I can return them. Also at 1/3 of the price of Brembo n OEM stuff, both of which are out of stock in Australia anyway, its hard not to at least give them a try.
I have no proof of this, however I believe really hard stops and keeping the brake applied can cause temperature differences across the rotor leading to warping. This is less likely on a race bike than a street bike.
I looked at some Australian made or imported rotors and they were not symmetrical in design, so I went for others that have a lot of good feedback. They are Chinese I believe and I purchased them from MC Motoparts on eBay. Haven't fitted them yet.
Check for alignment of the calipers ect. And you need to bed in the new discs. My stock srad discs were warped to the point it was pushing the pads in i fitted neverland wavey dics and less then half price of stock ones its a good deal and now my bike stops well.
yeah ill be getting the calipers checked.
and of course bedding in the discs.
did you get any of that funny harmonic 'singing' vibration from the wavy discs?
I had them on my K1 1000 a few years back and I had that (only at certain speeds and brake pressure, not all the time) but it annoyed me, and it is a known problem with wavy discs...
