Cycling, whether for commuting, exercise, or pleasure, relies heavily on one critical component: the braking system. And at the heart of this system are brake pads. These small yet vital parts ensure your bike can stop efficiently and safely. Understanding brake pads, their types, usage, and how to choose and install them can significantly enhance your biking experience. This comprehensive guide will delve into every aspect of bike brake pads, providing you with all the information you need.
What are Bike Brake Pads?
Bike brake pads are components of the braking system that apply friction to the wheel rims or disc rotors to slow down or stop the bike. They are made of a friction material mounted on a metal backing plate. When you pull the brake lever, the brake pads are forced against the rim or rotor, creating the friction needed to stop the bike.
Types of Bike Brake Pads
There are several types of bike brake pads, primarily classified based on the type of braking system they are designed for. The two main categories are rim brake pads and disc brake pads.
Rim Brake Pads
Rim brakes are one of the oldest types of braking systems used on bikes. They work by applying pressure directly to the wheel rim. Rim brake pads are further divided into different types based on their material and the type of rim they are designed for.
