How to increase the brake force of my drum brakes
As bicycle mechanic in the Netherlands, I see a lot of these brakes. The drum shoes can become harder due to wear or age or something. They can also become a bit uneven.


Remove the brake
Use a good metal file to remove a very thin piece of the drum shoe
Make sure the entire drum shoe has a 'new' surface, and make sure this surface is even
Clean the drum with brake-cleaner or some other de-greasing stuff
Re-assemble and enjoy your quality retro bike


If the drum is to worn out, you can easily replace it.
