Understanding Front Bike Brakes

Before adjusting your front bike brakes, it’s essential to understand their anatomy and types. The most common brakes found on bikes are caliper brakes and disc brakes, both of which rely on the friction between the brake pads and the rim or rotor of the wheel to slow or stop the bike.

Caliper brakes are usually found on road bikes and consist of two brake arms attached to the frame. When the brake lever is squeezed, the arms close, bringing the brake pads closer to the rim, causing friction and slowing down the bike.

Disc brakes, on the other hand, use a rotor mounted directly on the wheel hub and a caliper that squeezes the brake pads onto the rotor, slowing the bike down. They’re found on a variety of bikes, from mountain bikes to road bikes, and offer better stopping power and control in wet conditions.

Both types of brakes use cables to actuate the brake mechanism when the lever is activated, but some bikes, particularly high-end models, use hydraulic fluid instead of cables to activate the brakes. Understanding the different types of bike brakes will help you identify the type of brake system on your bike and determine the best adjustments to make for optimal braking performance.
