Disk brake for Handcrat. Bollerwagen Bremse

In Germany, it's pretty common to take a handcart loaded with beer for a day out, especially during traditional events. But navigating downhill with cheaper handcarts can get tricky—and potentially unsafe.

To address this, I installed an affordable Shimano MT200 disc brake set on my handcart. The discs are mounted to the rims of the two front wheels, while the calipers are attached to the square tubing of the frame.

The setup performs surprisingly well! I printed the mounts in PETG with 8 outline layers for added durability. Air in the braking system wasn’t ideal, but it still worked effectively.

One challenge I faced was splitting the hose from the master cylinder to connect two brake calipers. My current solution has a slight leak, so I have to top it off before each use. There are likely better options out there for splitting the line—perhaps a dedicated product exists. Another idea could be to use a single brake disc and connect both front wheels via a rotating axle.

Beyond the brakes, I also reinforced the handcart itself. The axle was misaligned, and the steering mount had broken. While I fixed the steering temporarily, it didn’t hold up under stress.

If you’re interested in replicating this setup, I’ve uploaded all the files, including the .f3d files. Keep in mind that you may need to adjust the tolerances for a proper fit.

Apologies for the rough modeling—I was racing against the clock!
