TOYOTA 90947-02716 Brake Hose

This genuine TOYOTA brake hose (part number: 90947-02716) is a premium-quality factory original part that guarantees the safe and reliable operation of the vehicle's hydraulic braking system. The flexible brake hose plays a crucial role in transmitting hydraulic brake pressure from the rigid brake lines to the moving brake calipers or wheel cylinders at the wheel, seamlessly accommodating suspension travel and steering movements.

Technical Features and Construction

• Material Composition: Manufactured from multi-layer, high-strength synthetic rubber (EPDM) with high-density internal reinforcement (synthetic fabric braid) engineered to withstand extreme hydraulic pressures and prevent volumetric expansion under load.
• Fittings: Features precision-machined, corrosion-resistant coated threaded metal fittings for an exact, leak-free hydraulic seal.
• Chemical Resistance: Fully compatible with standard brake fluids (DOT 3, DOT 4, and DOT 5.1), highly resistant to ozone, road salt, and extreme temperature fluctuations.
• Flexibility: High fatigue life engineered to endure continuous bending, flexing, and torsional stress caused by suspension dynamics.

Function and Signs of Wear

Because brake hoses are directly exposed to harsh environmental conditions and ongoing mechanical stress, they inevitably age and degrade over time. A compromised brake hose poses an immediate hazard to road safety.

Common signs of wear and failure:

• Surface cracking, brittleness, porosity, or hardening of the outer rubber jacket.
• Bulges or blistering on the hose wall under braking pressure (indicating internal braid rupture).
• Brake fluid leakage at the crimped metal fittings or along the hose body.
• A soft, spongy brake pedal feel and noticeably increased stopping distance.
• Vehicle pulling to one side under braking (caused by internal hose collapse or swelling restricting fluid flow).

For maximum driving safety, regular visual inspections during every routine service and prompt replacement with a genuine OEM part at the first sign of degradation are highly recommended.
