• Pressure Rating: Rated at up to 200 bar, the PHD397 can withstand extreme pressure spikes typical in high‑performance braking scenarios without compromising structural integrity.
• Temperature Range: Operates effectively between -40°C and +120°C, accommodating both cold climates and high‑temperature environments encountered during heavy braking.
• Flexibility & Durability: The hose’s flexible design allows for easy routing around vehicle components while maintaining a robust seal. Its reinforced construction resists kinking, ensuring long‑term reliability.
• Compatibility: Designed to fit a wide range of automotive models, including various Volkswagen, SEAT, and other European vehicles. The hose features standard fittings compatible with most brake system assemblies.

Installation & Maintenance Guidelines

Installing the TRW PHD397 is straightforward for technicians familiar with brake systems:

1. Preparation: Ensure all hydraulic fluid is drained and the vehicle’s braking system is depressurized before removal of the existing hose.
2. Removal: Carefully detach the old hose from both ends, taking note of any fittings or adapters that may need replacement.
3. Installation: Fit the new PHD397 hose onto the brake lines, securing it with appropriate clamps or fittings. Verify that the hose is free of twists and kinks.
4. Bleeding: After installation, bleed the braking system to eliminate air pockets, following manufacturer guidelines for fluid type and bleeding procedure.

Regular inspection is recommended to detect any signs of wear or damage. Replace the hose immediately if you observe bulging, cracking, or leaks, as these can compromise braking performance.

Performance Benefits

• Enhanced Safety: The high pressure tolerance and robust construction reduce the risk of hose failure during critical braking moments.
• Consistent Braking Response: Low‑friction inner lining ensures minimal fluid resistance, providing a more predictable brake feel.
• Longevity: Resistance to heat and chemical degradation extends service life, even under frequent hard braking or in harsh environmental conditions.
• Versatility: Suitable for both daily driving and performance applications, making it an ideal choice for a wide range of vehicle owners.
