If you are planning to upgrade your non-disc brake bike to disc brakes, it is important to understand how different brake systems work. In this section, we will discuss the two most common types of bike brake systems: disc brakes and rim brakes.

Disc Brakes vs Rim Brakes

Rim brakes are the traditional type of bike brakes that use rubber pads to grip the rim of the wheel. When you squeeze the brake lever, the pads press against the rim to slow down or stop the bike. Disc brakes, on the other hand, use a rotor attached to the wheel hub and a caliper that clamps onto the rotor to slow down or stop the bike.

Disc brakes have several advantages over rim brakes. They provide better stopping power, especially in wet or muddy conditions, and are less affected by rim wear. Additionally, they generate less heat, which reduces the risk of overheating the rim and tire. However, they are more complex and expensive to install and maintain than rim brakes.

Components of Disc Brakes

Disc brakes consist of several components, including the rotor, caliper, brake pads, and brake lever. The rotor is a metal disc that attaches to the wheel hub and rotates with the wheel. The caliper is a mechanism that houses the brake pads and clamps onto the rotor to slow down or stop the bike. The brake pads are made of a friction material that grips the rotor when the brake lever is squeezed. The brake lever is the component that you squeeze to activate the braking system.

There are two types of disc brakes: mechanical and hydraulic. Mechanical disc brakes use a cable to activate the caliper, while hydraulic disc brakes use fluid to activate the caliper. Hydraulic disc brakes provide better modulation and require less hand strength to operate than mechanical disc brakes. They are also self-adjusting, which means that they compensate for pad wear automatically.

In conclusion, understanding the different components and types of bike brake systems is essential when considering upgrading your non-disc brake bike to disc brakes. Disc brakes provide better stopping power and are less affected by rim wear, but they are more complex and expensive to install and maintain than rim brakes.
