I changed the front brake pads on my XB12S to Lyndall Golds about 6 months back. Yesterday, I noticed that the rotor is not wearing to well and that brake performance is not what is use to be. I am thinking about changing to EBC HH sintered pad but do I have to change my rotor as well?

No. just scuff the rotor up a bit with some scotchbrite or similar.

Interesting... It looks like the pads are worn enough to get to bare metal? If not, they don't seem to be wearing correctly. Did you bed them in?

I use the EBC HH's and they seem to work well on the street. I've never tried the Lyndall's, but Al from American Sport Bike recommends them as I recall.

In any case, I would need to look at your rotor in person but from what I can see I'd say I'd throw the new pads on (whichever ones you like). If the pads wore down to the metal and scaratched the rotor though... Get one of those cool wave rotors : ).

M1-
There is still a lot of pad left and I did bed them in as per the pad instructions. The rotors have about 4500 miles on them 1500 of those miles with these pads. There are some slight groves and high spots on the rotor and I'm sure they weren't there when I installed the pads. Anyway, just looking for advice as there is no point in being able to go fast if I cant stop.

If it were me I'd get new pads & a rotor and go from there.
Look like something went wrong there.
Can't say from a picture what went wrong though.
I trust Al, and I know he likes the Lyndall's a lot.
The track junkies I know like the EBC HH's.
When you changed the pads did you clean the caliper REALLY well?
You may have a stuck piston, happened to me once, and I killed a set of pads in nothing flat.

It does look funky, but I can't tell if the rotor is scored or if there's just two material types near the edges and they didn't react well together...

I'd say get out a set of calipers and check how deep the grooves are, and see if someone can fix it or not?

Al at American Sport Bike sells a really nice tool that will put a proper crosshatch pattern on your rotor. You have to pull the rotor, but it is worth the effort. Warning though. . . make sure you use new hardware when you reinstall the rotor.
