Hello! New to the forum, but I've been riding the Radwagon 2019 in Belgium since 2019, and it's an amazing vehicle.

Mostly driving my kids around, and cargo. I felt the brakes weren't enough, for safety when having the kids as well as when driving at 40km/h sometimes on my own for fun.

So I had some hydraulic brakes placed by someone, increasing the performance but they're just not right and incredibly squeaky...
Trying to adapt them by different people didn't work...

Are there currently any great hydraulic brakes for a simple old radwagon 2019 that is available for purchase somewhere?
These were recommended, but not available...
