NISSAN 46210-VB00B Brake Hose Assembly

This genuine OEM NISSAN brake hose assembly (part number: 46210-VB00B) is an essential safety component of the vehicle's hydraulic brake system. Its function is to transfer brake fluid under high pressure and without loss between the rigid brake lines and the moving wheel assemblies (brake calipers or wheel cylinders).

Technical Features and Construction

• Material Composition: Multi-layer, fiber-reinforced synthetic rubber designed to withstand high hydraulic pressure and ensure minimal volumetric expansion under load.
• Fittings: Precision-threaded, corrosion-resistant metal fittings ensuring a secure, leak-free seal.
• Fluid Compatibility: Fully compatible with standard brake fluids (DOT 3, DOT 4, DOT 5.1).
• Environmental Resistance: Excellent resistance to road salt, moisture, ozone, and extreme temperature fluctuations.

Symptoms and Importance of Brake Hose Wear

Brake hoses are subjected to continuous mechanical movement (steering, suspension travel) and environmental exposure, leading to aging over time. Common indicators of failure include:

• Visibly noticeable cracks, surface damage, or bulges on the hose.
• Brake fluid leakage at fitting connections or through the rubber surface.
• A spongy, soft brake pedal feel, indicating internal wall weakening and hose expansion.
• Uneven braking performance or the vehicle pulling to one side under braking.
