description Bike brake inner cable
The bike brake inner cable is a crucial component of the braking system, responsible for transmitting the force applied at the brake lever to the brake caliper or brake arm, ultimately resulting in the braking action that slows or stops the bike. Typically made of high-tensile steel, the inner cable is designed to withstand the tension and compression forces exerted during braking without stretching excessively.
It consists of a flexible, thin steel wire core that runs inside a protective outer housing. The core is often galvanized or coated to resist corrosion and maintain smooth operation. At each end of the inner cable, there are specialized fittings or heads that secure it to the brake lever and the brake mechanism. These fittings can vary depending on the type of brake system (e.g., caliper brakes, cantilever brakes, or disc brakes).
The outer housing of the brake cable provides protection and guides the inner cable along its path from the brake lever to the brake mechanism. It is usually made of wound metal or coiled wire strands lined with plastic or rubber to reduce friction and ensure smooth cable movement. The housing is secured to the bike frame and brake components with cable stops, ferrules, or other fasteners.
Maintaining the brake inner cable is essential for optimal braking performance. Regular inspection and lubrication help prevent cable wear, corrosion, and stiffness, ensuring that the brakes respond reliably and smoothly. When replacing the inner cable, it's important to choose a cable of the correct diameter and length suitable for the specific type of brake system on your bike.
