Rubbing rotor noise after rain

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Rubbing rotor noise after rain

Frequently after I ride in wet weather or with wet roads I start getting faint rubbing type noises that seem like they are minor debris or dirt by the brake rotors. The only way I've found to clean effectively is removing the wheels and giving a thorough cleaning. Are there any simpler ways? Do others have this issue?

I employ a very simple solution - I do nothing and it almost always goes away on its own.

You might need new pads. Worn pads aren't smooth, and will have pits and grooves that collect dirt which then rubs and makes noise (but comes off with a little braking). This will wear the rotors.

Fair enough. I just hate noises. I’ll just have to try to ignore.

How persistent is the noise? If it's lasting in to the next ride and longer, you may have fouled pads.

Happens to our cars, too. Disc brakes self-adjust to fairly tight clearances between the rotor and pads, and steel expands where it rusts. So that clearance goes away until the surface rust wears off.

Well, disc brake rotors have advantages as sound transducers over wheel rims. The rims are heavier and damped by tires and tubes, while the disc rotors are metal rings that are mostly spinning freely through the air and fastened at a few points.

Completely irrelevant, since rim brakes barely ever rub.

Ignore him or it'll eventually drive the thread in to a morass of Big Bike Marketing rants with the occasional detour on the evils of cartridge bearings.

Sorry not sorry for pissing on your hubs, the point is to give a pat on the back to anyone still building them right. But my degree of concern for the possibility of a better world does seem a bit unusual, so what do I know.
