TRW Automotive AfterMarket PHD179 Brake Hose

TRW Automotive AfterMarket PHD179 Brake Hose – The Ultimate Performance Component

The TRW PHD179 Brake Hose is engineered to deliver uncompromised safety and reliability in every braking scenario. Designed for high-performance vehicles, this hose combines advanced materials with meticulous construction to ensure consistent hydraulic pressure, superior heat resistance, and long-term durability.

Key Design Features

High-Temperature Silicone Core: The inner lining of the PHD179 is a premium silicone elastomer that can withstand temperatures up to 250 °C (482 °F). This capability protects against heat buildup during heavy braking, preventing hose failure and maintaining optimal brake fluid pressure.

Multi-Layer Construction: The hose features a multi-layered structure: an inner silicone core, a reinforcing layer of high-strength polyester or nylon braid, and an outer protective sheath. This combination resists abrasion, flex fatigue, and external damage while preserving the hose’s flexibility.

Precision Threading: Both ends are machined to M10x1 threads (or equivalent), ensuring a tight seal with brake lines and calipers. The threading is designed for quick installation and secure attachment, minimizing the risk of leaks.

Performance Advantages

Consistent Hydraulic Pressure: The low-compliance silicone core maintains stable pressure transmission even under rapid temperature changes, guaranteeing reliable braking performance during aggressive driving or racing conditions.

Extended Service Life: With its robust construction and high-quality materials, the PHD179 offers a service life that exceeds many standard brake hoses. It resists cracking, swelling, and fluid absorption, which are common failure modes in lower-grade hoses.

Enhanced Safety: By preventing brake fluid leakage and maintaining pressure integrity, this hose plays a critical role in vehicle safety systems. Its reliability is essential for both everyday driving and high-performance applications where braking demands are extreme.

Compatibility Overview

The PHD179 is specifically engineered to fit Toyota Corolla VI Compact, Corolla VI Liftback, and other models that use the 484 mm M10x1 thread configuration. Its universal design also makes it suitable for a wide range of aftermarket brake systems, ensuring seamless integration with existing components.

Installation Guidelines

1. Preparation: Clean all mating surfaces to remove debris and old sealant. Inspect the hose for any visible damage before installation.
2. Threading: Apply a thin layer of brake fluid or compatible thread sealant to the threads on both ends of the hose. This step ensures a leak-free connection.
3. Connection: Screw the hose onto the caliper and line ends, tightening gradually in a cross-pattern to distribute torque evenly.
4. Flushing: Once installed, flush the brake system with fresh fluid to eliminate air pockets. Bleed the brakes according to manufacturer specifications.

Maintenance Tips

Although the PHD179 is built for longevity, routine checks can further extend its life:

• Visual Inspection: Periodically examine the hose for signs of swelling, cracking, or discoloration.
• Fluid Quality: Replace brake fluid as recommended to avoid contamination that could degrade the silicone core.
• Temperature Monitoring: In high-performance setups, monitor operating temperatures. If the hose consistently reaches extreme heat, consider additional cooling measures.
