Benefits of Mechanical Brakes:
The most notable benefit of Mechanical Disc brakes is that maintenance is easy. These brakes are also less expensive, and you only need to get the cables and pads replaced. In case an issue arises while on the road, you can fix it with ease as long as you have your Allen key. It is worth mentioning that Mechanical Disc brakes function more efficiently. A tension steel cable gets the pistons activated, and this compresses the brake pads against the rotor.
Mechanical Disc brakes offer lesser modulation, especially when riding in poor conditions. There is more friction within the brakes housing, and this, coupled with the fact that the system is exposed to dirt and debris, can cause untimely breakdowns. You may also want to know that the cables stretch over time.
Benefits of Hydraulic Brakes:
The modulation of Hydraulic Disc brakes is without debate impressive. Cyclists are in total control of their stopping speed, and this promotes safety irrespective of the terrain or weather conditions. Additionally, less effort is needed to stop, and all you need to do is use a finger to squeeze the brake lever. Hydraulic brake systems are fully enclosed, and this reduces exposure to elements that can mess with their longevity.
On the downside, fixing failed brakes on the go is nearly impossible. Hydraulic brakes also tend to be more expensive than their Mechanical counterparts. Moreover, maintenance of Hydraulic Disc brakes is technical and messy.
