TRW Automotive AfterMarket PHD942 Brake Hose

TRW Automotive AfterMarket PHD942 Brake Hose

The PHD942 is a high‑performance, flexible brake hose designed for modern automotive braking systems. Manufactured by TRW, a leader in automotive safety components, this hose delivers reliable hydraulic pressure transmission while withstanding the demanding conditions of everyday driving and racing environments.

Key Design Features

• Dual‑Layer Construction: The inner layer is made from reinforced rubber that resists abrasion and chemical degradation, while the outer layer consists of a durable polymer coating that protects against UV exposure, heat, and oil.
• High Pressure Rating: Capable of handling pressures up to 200 bar, ensuring consistent brake performance even under extreme braking forces.
• Temperature Resistance: Operates effectively between -40°C and +120°C, maintaining flexibility in cold climates and retaining integrity at high temperatures generated during heavy braking.
• Pre‑sealed End Fittings: Each hose comes with pre‑installed, corrosion‑resistant fittings that simplify installation and guarantee a leak‑free seal.
• Extended Lifespan: Designed to last through thousands of miles of service life, reducing the need for frequent replacements.

Compatibility and Applications

The PHD942 is engineered to fit a wide range of vehicles across multiple brands. Its standardized dimensions and fittings make it suitable for:

• Volkswagen models such as the Golf IV, Bora, and Passat.
• Audi series including TT, A4, and Q3.
• Skoda vehicles like Octavia and Superb.
• Seat models ranging from Ibiza to Leon.
• Other OEMs that use the same brake hose specifications.

Whether you are upgrading a stock system or installing a high‑performance braking setup, the PHD942 offers a reliable solution for both front and rear brake lines.

Installation Guidelines

1. Preparation: Clean all mating surfaces with isopropyl alcohol to remove grease or contaminants. Inspect the hose for any visible damage before installation.
2. Fitting Connection: Align the pre‑sealed fittings with the corresponding brake line ports. Use a torque wrench to tighten each fitting to the manufacturer’s specified torque value, typically around 12–15 Nm.
3. Bleeding Procedure: After installation, bleed the braking system according to the vehicle’s service manual to eliminate air pockets and ensure optimal hydraulic performance.
4. Safety Check: Verify that all connections are secure and that there is no leakage under pressure before taking the vehicle on a test drive.

Performance Benefits

The PHD942 brake hose enhances overall braking efficiency by maintaining consistent hydraulic pressure throughout the system. Its robust construction reduces the risk of hose failure, which can lead to sudden loss of braking power—a critical safety concern. Additionally, the hose’s flexibility allows it to accommodate suspension movement without compromising seal integrity.

Maintenance Tips

• Inspect hoses annually for signs of wear such as cracks, bulging, or discoloration.
• Avoid exposure to harsh chemicals that can degrade rubber components.
• Replace the hose if any damage is detected, even if the vehicle has not yet reached its expected service life.
