What causes noisy drum brakes?

What do bad drum brakes sound like?

Why does my motorcycle make noise when I brake?
If you have a squeak, squeal or pinging noise that occurs while you are riding at regular intervals, it is usually a caliper alignment issue or a bent rotor that is causing your brake pads to rub as you ride.

How do you fix squeaky motorcycle drum brakes?
The only way to stop the squeak is to either have the rotors machined or replaced. Another reason is either cheap pads were installed or the pads were installed incorrectly or brake pad shims weren’t installed properly or left out when the brake job was done. Good luck and hope this helps.

In this case, a change to a softer lining material may make the noise go away. Inspect the brake linings to see if they are worn out or damaged. If the lining is completely worn or has failed, then the metal backing on the shoe will contact the drum during braking, and a loud grinding or scraping noise will result.
