When it comes to cycling, being able to stop your bike is just as important as being able to ride it. That’s why understanding how your bicycle brake system works is crucial. In this section, we will cover the different types of bicycle brakes and the components that make up the brake system.
Types of Bicycle Brakes
There are two main types of bicycle brakes: disc brakes and rim brakes.
Disc Brakes
Disc brakes use a caliper to squeeze the brake pads against a rotor attached to the wheel hub. This creates friction, which slows down the wheel and stops the bike. Disc brakes can be further divided into hydraulic disc brakes and mechanical disc brakes.
Hydraulic disc brakes use a piston in the caliper to push brake fluid through a hydraulic system, which applies pressure to the brake pads. This results in a very powerful and consistent braking performance, but they can be more expensive and require more maintenance.
Mechanical disc brakes, on the other hand, use cables to pull the caliper and brake pads together. They are less expensive and easier to maintain, but they may not offer the same level of braking power as hydraulic disc brakes.
Rim Brakes
Rim brakes, also known as caliper brakes, use a caliper to squeeze the brake pads against the rim of the wheel. This creates friction, which slows down the wheel and stops the bike. Rim brakes are less expensive and easier to maintain than disc brakes, but they may not perform as well in wet or muddy conditions.
Components of Brake Systems
Regardless of the type of brake system, there are several components that make up the brake system:
-
Brake Pads: These are the replaceable pads that come into contact with the wheel rim or rotor to create friction and stop the bike. The lifespan of brake pads can vary depending on factors such as weather, terrain, type of riding, and weight of the rider. On average, they can last between 400-2000 miles [1].
-
Caliper: This is the part of the brake system that holds the brake pads and applies pressure to them.
-
Rotor: This is a metal disc attached to the wheel hub that the brake pads come into contact with in a disc brake system.
-
Wheel: This is the rotating part of the bike that the brake system is applied to.
-
Hydraulic System: This is the system used in hydraulic disc brakes to transmit force from the brake lever to the caliper. It consists of brake fluid, hoses, and pistons.
-
Cables: This is the system used in mechanical disc brakes and rim brakes to transmit force from the brake lever to the caliper.
-
Levers: These are the brake controls on the handlebars that activate the brake system.
In the next section, we will discuss how to change brake pads on both disc and rim brake systems.
