Description
Brake Pipe To ABS And ESP Module For Citroën And Peugeot Vehicles
This brake pipe is designed to connect the vehicle hydraulic circuit to the ABS/ESP control module on Citroën and Peugeot models. It is a direct-fit hydraulic line intended for professional garages and competent DIY mechanics who service braking systems. The part is commonly searched under product codes 4887T3 and 4887T2 and fits applications where the original pipe has been damaged, corroded or leaks at the fittings. Replacing a worn or leaking brake pipe restores proper hydraulic integrity for ABS and ESP operation and helps prevent loss of braking performance and warning lights related to the ABS system.
Function And Application
The brake pipe carries pressurised brake fluid between the master cylinder and the ABS/ESP module or between the module and wheel circuits. It must maintain leak-free performance under vibration, temperature changes and road contaminants. A correct, undamaged pipe ensures the ABS/ESP system can modulate pressure reliably during emergency braking and stability interventions.
How To Replace
- Park vehicle on a level surface, engage parking brake and block wheels.
- Loosen wheel nuts if required and access the damaged pipe or the ABS/ESP module mounting area.
- Prepare to capture brake fluid (use a suitable container) and protect painted surfaces from spills.
- Carefully disconnect the hydraulic fittings at both ends using line wrenches to avoid rounding soft fittings.
- Remove any retaining clips or brackets and replace the pipe with the new unit, ensuring correct routing and secure clamps.
- Reconnect fittings and torque to manufacturer specification where available.
- Bleed the brake system thoroughly to remove air (use a pressure bleeder or two-person method). Use the brake fluid type specified by the vehicle manufacturer (many Citroën/Peugeot models use DOT4; always confirm before filling).
- Check for leaks under pressure and road-test the vehicle carefully. Recheck fittings after a short test drive.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Peugeot 407 (and Related Citroën/Peugeot Applications)
- Product Codes: 4887T3, 4887T2
- Other Numbers: NFP
Installation Recommendations
- Work Should Be Performed By A Qualified Mechanic Or An Experienced DIY Technician Familiar With Brake Systems.
- Use Correct Line Wrenches And Avoid Damaging Flare Fittings. Replace Any Damaged Sealing Rings Or Clips.
- Always Use The Brake Fluid Specified By The Manufacturer And Dispose Of Old Fluid Responsibly.
- After Replacement, Bleed The System Completely To Remove All Air; An Incomplete Bleed Can Cause Soft Pedal And Reduced Braking Efficiency.
- Inspect Nearby Components (Hoses, Calipers, ABS Module Connections) For Corrosion Or Damage While The System Is Open.
Why This Part Most Frequently Fails
- Corrosion From Road Salt And Moisture Leading To Metal Degradation And Leaks.
- Mechanical Damage From Road Debris Or Contact With Suspension Components.
- Fatigue At Bends Or Connection Points Due To Vibration And Thermal Cycling.
- Improper Installation Or Repeated Disconnects That Damage Fittings Or Seals.
