Performance Benefits

The TRW PSA116 Brake Booster delivers a number of tangible advantages for both commercial fleets and private vehicle owners:

• Reduced Pedal Effort: The vacuum assistance significantly lowers the force required at the brake pedal, enabling smoother stops even under heavy load.
• Consistent Braking Response: Rapid fluid flow ensures that braking pressure is applied evenly across all wheels, maintaining vehicle stability during emergency maneuvers.
• Enhanced Safety: By integrating with ABS systems, the booster helps prevent wheel lock‑up, preserving steering control when brakes are applied hard.
• Longevity and Reliability: The robust alloy construction resists wear and tear, extending service life even in demanding operating environments.

Installation Overview

Installing the TRW PSA116 Brake Booster is straightforward for technicians familiar with brake system assembly:

1. Disconnect the existing master cylinder and remove any mounting brackets.
2. Clean the mounting surface to ensure a proper seal.
3. Position the new booster, aligning it with the vacuum hose and hydraulic lines.
4. Screw in the mounting hardware, tightening to manufacturer specifications.
5. Reconnect the vacuum line and brake fluid reservoir; bleed the system to eliminate air pockets.
6. Verify ABS functionality by performing a diagnostic check on the vehicle’s electronic control unit.

Maintenance Guidelines

Regular maintenance ensures optimal performance:

• Brake Fluid Inspection: Check fluid levels and quality every six months; replace if contaminated or degraded.
• Vacuum Line Check: Inspect for leaks or cracks; repair or replace as needed to maintain vacuum integrity.
• Seal Integrity: Examine O‑rings and gaskets for wear; replace before failure occurs.
• Visual Inspection: Look for signs of corrosion, cracking, or deformation on the booster body.
