PSA444 TRW SERVO OE QUALITY

PSA444 TRW Servo OE Quality

The PSA444 TRW Servo OE Quality is a high‑performance brake booster designed to deliver exceptional stopping power and precise pedal feel for modern vehicles. Engineered with the same rigorous standards as original equipment (OE), this component ensures reliable operation under demanding driving conditions.

Key Features

• Premium Construction: Made from high‑strength aluminum alloy and reinforced steel, providing durability while keeping weight low for optimal vehicle dynamics.
• Advanced Sealing Technology: Dual O‑ring system and precision‑molded seals prevent air leaks, maintaining consistent vacuum pressure throughout the brake circuit.
• Optimized Geometry: The internal chamber is engineered to maximize airflow efficiency, delivering a smooth, progressive pedal response that feels natural to drivers.
• Compatibility: Designed for use in a wide range of Ford models—including Focus, Kuga, C‑Max, and others—where the PSA444 reference is specified. Also suitable for Subaru SVX and other vehicles requiring a robust brake booster.
• Easy Installation: Features standardized mounting points and quick‑connect fittings that align with OEM specifications, allowing technicians to replace the unit without extensive modifications.

Performance Benefits

The PSA444 servo delivers a significant boost in braking force, reducing stopping distances by up to 15% compared to standard aftermarket boosters. Its precise vacuum control ensures that the brake pedal remains responsive even under high‑temperature conditions, preventing fade and maintaining consistent performance during repeated hard stops.

Engineering Excellence

Developed in collaboration with TRW’s extensive research and development team, this servo incorporates cutting‑edge materials science. The aluminum alloy used for the housing is treated with a proprietary anodizing process that resists corrosion and wear. Inside, the diaphragm is fabricated from high‑grade elastomer that retains elasticity over thousands of cycles.

Installation Overview

1. Disconnect Battery: For safety, remove the negative battery terminal before working on the brake system.
2. Remove Old Booster: Detach the vacuum hose and disconnect the mounting bolts that secure the booster to the chassis. Carefully lift the unit out of its bay.
3. Position New PSA444: Align the mounting holes with the vehicle’s bracket, ensuring a snug fit. Tighten the bolts to the manufacturer’s torque specification.
4. Reconnect Vacuum Lines: Attach the vacuum hose to the new booster’s inlet and secure it with a hose clamp. Verify that all connections are tight to prevent leaks.
5. Test Pedal Feel: Reconnect the battery, then press the brake pedal several times to confirm smooth operation and proper vacuum pressure.

Maintenance Tips

• Inspect the O‑rings annually for signs of cracking or wear. Replace them if any damage is observed.
• Check the vacuum hose for kinks or leaks; replace it if necessary to maintain optimal pressure.
• Keep the booster housing clean and free from debris that could interfere with mounting or airflow.
