TRW Automotive AfterMarket PHB555 Brake Hose

TRW Automotive AfterMarket PHB555 Brake Hose

The TRW PHB555 brake hose is a high‑performance hydraulic component designed to deliver reliable braking power in a wide range of automotive applications. Engineered with precision and built to meet stringent safety standards, this flexible hose provides the essential connection between the master cylinder and the wheel cylinders or calipers, ensuring that every pedal push translates into effective stopping force.

Key Features

• Durable Construction: Made from premium quality rubber reinforced with a multi‑layered steel braid, the hose resists abrasion, heat, and chemical exposure. This construction guarantees long service life even under demanding driving conditions.
• High Pressure Capacity: Rated for pressures up to 300 bar (4350 psi), the PHB555 can handle the demands of modern braking systems without compromising integrity or performance.
• Temperature Resistance: Operates effectively across a wide temperature range, from -40 °C to +120 °C. This ensures consistent hydraulic fluid flow regardless of ambient conditions or engine heat.
• Leak‑Proof Design: Equipped with a robust sealing system that prevents fluid loss and maintains optimal brake pressure during operation.
• Compatibility: Designed to fit a broad spectrum of vehicles, including Volkswagen Transporter models (7HA, 7HH, 7EA, 7EH), Multivan 5, and other commercial vans. The hose’s fittings are engineered for easy installation with standard brake line connectors.

Material Composition

The PHB555 employs a dual‑layered construction: an inner layer of high‑grade rubber that provides flexibility and chemical resistance, surrounded by a steel braid that offers tensile strength and dimensional stability. The outer sheath is made from reinforced synthetic material to protect against environmental wear.

Installation Guidelines

1. Preparation: Ensure the brake system is depressurized before handling. Clean all fittings and hoses with a suitable solvent to remove grease or contaminants.
2. Fitting Connection: Slide the hose onto the master cylinder outlet, aligning the threaded ends. Tighten securely using an adjustable wrench, but avoid overtightening which could damage the threads.
3. Securing the Hose: Use appropriate hose clamps or fittings to secure the hose along its length, preventing movement that could lead to wear or leaks.
4. Bleeding Procedure: After installation, bleed the brake system according to vehicle specifications. This removes air bubbles and ensures optimal hydraulic performance.

Maintenance Tips

• Inspect hoses annually for signs of cracking, bulging, or discoloration.
• Check fittings and clamps for tightness; replace if worn.
• Avoid exposure to extreme temperatures or direct sunlight for extended periods.
• Replace the hose if any leakage is detected during operation.

Performance Benefits

The TRW PHB555 brake hose delivers consistent hydraulic pressure, which translates into reliable stopping power. Its robust construction minimizes flexing under load, reducing the risk of brake fade and ensuring that drivers experience smooth, predictable braking responses even during heavy-duty use.

Safety Considerations

Brake hoses are critical safety components. A compromised hose can lead to sudden loss of braking ability. The PHB555’s high‑pressure rating and leak‑proof design provide an added layer of safety, reducing the likelihood of failure under normal operating conditions.

Applications

The versatility of the TRW PHB555 makes it suitable for:

• Commercial vans and transporters requiring robust braking systems.
• Passenger vehicles with high-performance brake demands.
• Aftermarket upgrades where OEM hoses may not meet specific performance criteria.
