Rhino, IIRC they've changed something since the first couple of years, possibly only the pads? I had bad chatter/pulsing when braking hard. Might a good cleaning have solved my problem? Possible. Starting fresh with EBC didn't break the bank for me, plus I get to do a thorough cleaning and I get to ensure all my bolts are torqued to spec. None of my caliper, pinch bolt, or rotor bolts were right. I think 25 ft-lbs is the highest value for any of those bolts, and my bike had them set to 'oh my god I'm gonna blow hemorrhoids out my arse getting them loose'. Tight might be good, but over-tight can be bad.
