TRW Automotive AfterMarket PHD479 Brake Hose

TRW Automotive AfterMarket PHD479 Brake Hose Overview

The TRW PHD479 brake hose is a high‑performance component engineered for modern automotive braking systems. Designed to replace original equipment or upgrade existing setups, it delivers reliable hydraulic pressure transmission while withstanding the demanding conditions of everyday driving and spirited performance.

Key Design Features

• Dual‑Layer Construction: An inner layer of reinforced braided steel wire provides exceptional tensile strength, while an outer elastomeric sleeve protects against abrasion, heat, and chemical exposure.
• High‑Temperature Resistance: The hose maintains integrity up to 200 °C, ensuring consistent brake fluid flow even during aggressive driving or prolonged braking.
• Pressure Rating: Rated for a maximum operating pressure of 300 psi (2 bar), suitable for both standard and high‑performance brake systems.
• Flexible Design: The hose’s flexible profile accommodates tight routing spaces, reducing the risk of kinks or damage during installation.
• Corrosion‑Resistant Fittings: Stainless steel or brass fittings (depending on model) resist rust and corrosion, extending service life.

Material Composition

The inner braided layer consists of high‑strength steel wires coated with a protective polymer to prevent galvanic corrosion. The outer sleeve is made from a premium elastomer blend that resists ozone, UV light, and brake fluid degradation. Together, these materials provide a durable, long‑lasting hose capable of handling the dynamic forces within a braking system.

Compatibility Matrix

The PHD479 series is engineered to fit a wide range of vehicles, particularly those from the Mini family and other compact cars. Below is an overview of common applications:

Installation Guidelines

1. Preparation: Drain the brake fluid reservoir and purge the system to remove air. Ensure all fittings are clean and free of debris.
2. Routing: Route the hose along the vehicle’s original path, avoiding sharp bends or contact with hot engine components.
3. Securing Fittings: Tighten all connections to the manufacturer’s specified torque settings. Use a calibrated torque wrench for precision.
4. Purge Procedure: Refill the brake system with fresh fluid and purge air by cycling the brakes until consistent pressure is achieved.
5. Inspection: After installation, inspect the hose for any signs of kinks, leaks, or abnormal wear before taking the vehicle on a test drive.

Maintenance & Longevity Tips

• Regularly check for visible damage such as cuts, abrasions, or bulges. Replace immediately if detected.
• Avoid exposure to harsh chemicals beyond standard brake fluid; store the hose in a cool, dry place when not installed.
• Inspect fittings annually for tightness and corrosion. Re‑torque if necessary.
• When replacing the entire braking system, consider swapping all hoses to maintain uniform performance.

Performance Benefits

The TRW PHD479 brake hose offers several advantages over generic aftermarket options:

• Consistent Hydraulic Flow: The reinforced braid ensures minimal pressure drop, translating into more responsive braking.
• Reduced Wear: High‑quality elastomer resists wear from brake fluid and temperature cycling, extending service intervals.
• Enhanced Safety: With a robust pressure rating and corrosion-resistant fittings, the hose reduces the risk of failure under high load conditions.
