Before diving into the process of how to change bicycle brake cable, it’s crucial to understand the different types of brake systems and cables commonly found on bicycles. This knowledge will help you identify the correct cable for your bike and ensure compatibility.

Types of Bicycle Brake Systems

* **Rim Brakes:** These brakes use levers to pull brake pads against the rim of the wheel. Common types include:
* **V-Brakes:** Known for their strong stopping power, often found on mountain bikes and hybrid bikes.
* **Cantilever Brakes:** An older design, less common now but still found on some vintage bikes.
* **Side-Pull Brakes:** Typically found on road bikes, offering a balance of performance and weight.
* **Disc Brakes:** These brakes use calipers to clamp brake pads against a rotor attached to the wheel hub. They offer superior stopping power, especially in wet conditions.
* **Mechanical Disc Brakes:** Use cables to actuate the brake caliper.
* **Hydraulic Disc Brakes:** Use hydraulic fluid to actuate the brake caliper, offering more consistent performance and less maintenance (though bleeding is required from time to time).

Types of Bicycle Brake Cables

Bicycle brake cables consist of two main components: the inner wire and the outer housing. The inner wire transmits the force from the brake lever to the brake caliper or arms, while the housing provides support and guides the inner wire.

* **Inner Wires:**
* **Road Bike Cables:** Typically have a mushroom-shaped end that fits into road bike brake levers.
* **Mountain Bike Cables:** Typically have a barrel-shaped end that fits into mountain bike brake levers.
* **Universal Cables:** Some cables have both a mushroom and barrel end, allowing them to be used with either road or mountain bike levers. These are convenient, but always double check fitment.
* **Outer Housing:**
* **Standard Housing:** Consists of a coiled steel wire covered in a plastic sheath. It’s flexible and affordable.
* **Compressionless Housing:** Features a series of tightly wound wires running lengthwise, providing more precise braking feel and less cable stretch. Often used with disc brakes.

**Key takeaway:** When selecting a new brake cable, it’s essential to match the inner wire end to your brake lever type (road or mountain) and choose a housing that’s compatible with your brake system (standard or compressionless). Mismatched cables can lead to poor braking performance or even failure.
