Thank you! Excellent tips. I never knew what a bobbin is! If I get OEM pads, is cleaning the rotors imperative? Or maybe just a little wipe with brake parts cleaner?
You may not need to clean the bobbins, but with the OEM rotors I strongly recommend it.
I used spray brake cleaner and an allen key that just fitted inside each bobbin. Others have used a bolt & nut to turn the bobbin.
If you twist the allen key whilst pushing it off-center it grips the bobbin and allows you to turn it.
Once it turns freely, move to the next bobbin. You'll be surprised at how much crud comes out with just the spray.
The Kawasaki OEM pads are good but quite pricey.
The EBC HH or SBS HH (Street) pads are better, cheaper, and will last just as long.
