NISSAN 46356-0E00A Brake Hose Banjo Bolt

The genuine NISSAN 46356-0E00A (alternative part number: 463560E000) brake hose bolt (factory designation: BOLT-EYE or banjo bolt) is a critical hydraulic fastener in the vehicle brake system. This specialized hollow bolt ensures a tight, leak-free connection of the brake hose to the brake caliper or master cylinder while allowing brake fluid to flow freely through its internal ports.

Technical Characteristics and Specifications

• Manufacturer: NISSAN (Genuine OEM part)
• Part Number: 46356-0E00A (Replacement/OEM number: 463560E000)
• Part Type: Brake Hose Through-Bolt (Banjo Bolt)
• Material: High-tensile steel with corrosion-resistant surface treatment
• Application: High-pressure connections of hydraulic brake systems

Function and Importance in the Brake System

The brake hose bolt (BOLT-EYE) plays a key role in maintaining hydraulic pressure. Precision-drilled ports through the center and side of the bolt ensure that the pressure generated when depressing the brake pedal transfers without loss to the brake caliper pistons. Since the brake system operates under extremely high working pressures, the material quality and dimensional accuracy of the bolt are essential for safe stopping performance.

Signs of Wear or Failure

• Brake Fluid Leakage: Moisture or fluid droplets appearing at the brake hose union, which can lead to reduced braking efficiency.
• Thread Damage: Stretched or stripped threads resulting from improper tightening torque (over-torquing).
• Corrosion: Rusting caused by road salt and moisture that can compromise the structural integrity of the fastener.

Notice: Whenever replacing the brake hose bolt, it is always recommended to replace the copper or aluminum sealing washers to guarantee a proper seal.
