My hydraulic rim brakes on my Tandem are much easier on the hands and stop better than any disk brake I have ever used. Being a low pressure closed hydraulic system has made it so I don't need to replace the mineral oil. They have worked fine for around 20 years. The only maintenance is changing the pads and you need no tools to do this. The pads are less expensive and last several times longer than disk pads. Disk brakes are a high maintenance overpriced money pit compared to hydraulic rim brakes.
