Thank you for replying. I jacked up the right front wheel and it turns out the caliper piston was binding. Causing the back pad to shutter against the rotor. Fortunately I was able to do a warranty exchange. Greased everything up, bled the brakes and she’s 100% again!
It’s rather sad to see parts don’t last as long as they used to. The factory calipers lasted 22 yrs. before they started seizing. This one only lasted 1yr 2mths. Ohh well.
