I have been riding a gravel bike (Kona Rove NRB DL https://www.konaworld.com/rove_nrb_dl.cfm) for a year now. It has developed a tendency to drag the pads of the front brakes against the disc. I recently had the pads and rotor, front and rear, replaced (about 5,000 Km of use). As I ride, a noise comes from the front brake that suggests that the pads are touching the rotor, and it increases in volume until I "blip" the lever, which makes it go away for maybe another Km or so--or less.

Has anyone encountered this before? if yes, how did you solve it?

Yikes, you must do a lot of braking. 3K miles for a rotor doesn't seem like much.

Anyway, you may just need to reset your pistons. https://www.epicbleedsolutions.com/r...liper-pistons/ If that doesn't work, then the next thing is checking to make sure the caliper is centered. Like Andrew says, just follow the instructions for installation/alignment. https://www.youtube.com/watch?v=uk_nC9anQcM&t=13s

If that doesn't do it, check to make sure that both pistons are retracting. I have a piston that will drag occasionally, and I need to clean it. Follow this routine: https://www.youtube.com/watch?v=vQXF...&feature=youtu

I just got around to watching those.

The last procedure especially seems to be a real pain. And it's required
by mere dirt? Sheesh.
