Not sure if Rad updated the brake pads since my 2016 Radrover? I had to upgrade my brakes/Pads to Spykes TRP mechanical brakes after about 1000-1200 miles. I started work commuting with my Radrover at 55-75 miles per week with speeds up to 22-25 mph on some downhill runs with average speeds of 17-22 mph on level ground. The original Rad brakes took constant adjustments, noisy, longer emergency stops, and looked like they were glazed over a little bit from double-digit mph stops.
About +2 years with Spykes and +2500 miles and zero issues with noise, emergency stops, or glazed pads. I did Jagwire MTB brake cables at the same time when I upgraded the brakes. I feel way more comfortable with Spykes brakes when I need to do an emergency stop at +20 mph with a +75 lbs ebike and me in at +270 lbs.
