Rollerbrakes very noisy when used One of my bikes has "rollerbrakes" (commuter bike). When I brake very gently, they work silent. If I squeeze the brakes a liiitle more, I hear a terrible metal to metal screaching sound. It makes pedestrians jump out of the way, which is an undesired side effect (well, most of the time). Should I adjust them? grease them? replace them? ...
Roller Brakes (a form of drum brake) do need a regular service, which does require grease (yes it does seem weird to grease brakes) as there are some moving parts that can rub. You should be able to buy some Roller Brake grease/oil and apply to the appropriate location. I am not 100% familiar with Roller Brakes, so you may need to check the location in your manual, or perhaps someone else can help out with the description of rubber cover if needed.
