Description

Brake line to ABS ESP module for CITROEN C4 II and PEUGEOT 308 T7 cars

Part description

This used brake line is intended for connection to the ABS/ESP module. It is an important part of the brake system, which ensures the passage of brake fluid between the individual elements of the system. For this type of part, the correct shaping, the execution of the ends and the matching of the product numbers are essential.

The part is suitable for those who are looking for an original solution for Citroën and Peugeot cars, often according to the manufacturer’s designation. When repairing brakes, the correctly selected pipe is important not only for the functionality of the system, but also for the safe operation of the vehicle.

Installation recommendations

Generally/typically for this type of part, the exact replacement procedure may vary depending on the specific car design and access to the ABS/ESP module. The brake system needs to be worked on carefully, cleanly and with an emphasis on safety.

1) Before assembly

• Carefully compare the used part with the old part – especially pipe shape, length, bends, routing and end type.
• Inspect the pipe for signs of mechanical damage, dents, cracks, excessive corrosion or damaged threads.
• Check the cleanliness of the pass-through parts and the sealing contact surfaces.
• Before starting work, secure the vehicle against movement and only work on a securely secured vehicle.

2) Necessary tools and materials

• common workshop tools
• wrenches suitable for brake lines and fasteners
• cleaning agent suitable for around brake components
• container for catching operating fluids
• protective gloves and dirt-free rags
• means for subsequent bleeding of the brake system

3) Step-by-step assembly procedure

1. Secure the vehicle securely and prepare a work area with good access to the pipe being changed.
2. Clean around the joints so that dirt does not get into the brake system during disassembly.
3. Place a suitable container under the impact site to catch the leaking liquid.
4. Carefully loosen the old pipe connection at both ends.
5. Release the pipe from the holders and guides, if used.
6. Remove the old part without unnecessary violence to avoid damaging the surrounding components.
7. Compare the old and new part one more time just before assembly.
8. Place the used pipe in the original route so that it is not under unnecessary tension and does not rub against other parts of the car anywhere.
9. Screw the ends by hand first to avoid stripping the thread.
10. Then tighten the joints evenly and secure the pipe in all original fittings.
11. Check that the pipe is not twisted, kinked or deformed.
12. Bleed the brake system according to the specific vehicle and its equipment.
• 4) Post-assembly checks and test drive/function verification
  • Check all connections for tightness.
  • Verify that the brake pedal has adequate resistance and behavior.
  • Inspect the piping when fully seated to make sure it is not touching any moving or sharp parts.
  • After a short test drive, visually check the connections and any signs of fluid leakage again.

  5) The most common assembly mistakes + how to avoid them

  • Exchanging a part according to a similar shape – always compare the product numbers and the design of the ends.
  • Damage to thread during assembly – make connections first by hand without using force.
  • Incorrect pipe routing – pay attention to the original route and correct seating in the holders.
  • Brake System Contamination – work clean and protect exposed parts from dirt.
  • Skip the final leak check – after assembly, always check before and after the test drive.

  Reasons why the part is damaged

  • Corrosion caused by age, humidity and exposure to road salt.
  • Mechanical damage from dirt, stones or improper intervention during previous repairs.
  • Deformation of pipes during unprofessional disassembly or assembly.
  • Material fatigue due to long-term operation and vibrations.
  • Damage to threads and ends due to improper loosening or tightening.
