What are the differences between hydraulic and mechanical disc brakes in terms of performance and maintenance?

Hydraulic disc brakes provide better braking performance and modulation compared to mechanical disc brakes. They require less effort to engage and offer more precise control. However, hydraulic brakes are more complex and may require specialized tools and knowledge for maintenance and repair. Mechanical disc brakes are simpler and easier to maintain but may not offer the same level of performance as hydraulic brakes.
