MOTORCYCLE MATERIAL Brake Cable Housing Black Outer Casing 5mm Flexible Axle
Brake cable housing, also known as brake cable outer sheath or housing, is a protective covering used for brake cables in bicycles. It encloses and protects the inner brake cable, providing a smooth and reliable interface between the brake lever and the brake caliper or brake mechanism.
Here are some key aspects of brake cable housing:
1. Material: Brake cable housing is typically made of a durable and flexible material, such as plastic or reinforced polymer. These materials are chosen for their ability to withstand the forces and environmental conditions encountered during cycling, including exposure to moisture, dirt, and mechanical stresses.
2. Diameter: Brake cable housing is commonly available in diameters ranging from 4mm to 5mm. The specific diameter required depends on the bicycle's braking system, including the type of brakes (e.g., rim brakes or disc brakes) and the manufacturer's specifications.
3. Compressionless Design: Brake cable housing is designed to be compressionless, meaning it maintains its shape when compressed. This design minimizes cable compression, ensuring direct and precise actuation of the brake lever and immediate response at the caliper or brake mechanism.
4. Lining: The inner lining of brake cable housing is typically made of a low-friction material, such as Teflon or a similar synthetic compound. This lining reduces friction between the inner brake cable and the housing, allowing for smooth cable movement and optimal braking performance.
5. End Caps: Brake cable housing is often equipped with end caps or ferrules at both ends. These end caps provide a secure attachment to the cable stops or housing guides on the bicycle frame. They also help prevent fraying or unraveling of the housing and ensure a proper connection to the brake caliper or mechanism.
When replacing or selecting brake cable housing, it is important to consider factors such as compatibility with the specific braking system, the diameter required, and any specific recommendations from the bicycle manufacturer or component manufacturer. Proper installation, including routing the housing correctly and ensuring secure attachment, is crucial for optimal braking performance and safety.
Regular inspection and maintenance, including checking for signs of wear, damage, or moisture ingress, are recommended to ensure the reliability and longevity of the brake cable housing.
