ARMACUNE BRAKE PIPES for all 'A' Series vehicles were introduced in 1990 as a high quality corrosion-resistant alternative to Original Equipment steel brake pipes. Fitted with Bonpart's exclusive tube nuts, anti-chafe sleeving (where appropriate) and distinctive end caps, they are now widely recognised as the best combination of quality and cost available to 'A' Series owners.

Unique in brake pipe design, these were developed by Citroen to absorb the movement of the rear wheel cylinders relative to the rest of the brake pipe system (caused by the rear axle arms' swinging movement on the axle tube). Ingeniously Citronesque, this design reduced the higher production costs of using flexible brake hoses - favoured by all other vehicle manufacturers!

Back in 1990, to determine the efficiency of Armacune Brake Tubing in this 'different' application, Bonapart arranged for independent fatigue testing of two Armacune 'curlies' by the Newtech Inovation Centre.

The conditions applied to the two tests were:

1. The axle arm was cycled through an angle of 53 degrees (Note: The maximum angle through which an 'A' Series axle arm will travel in situ is 45 degrees to Bump Stop.
2. The Cycling Frequency was 200 cycles per minute!
3. Brake fluid in each pipe was maintained at a constant 6 bar pressure.
4. Each pipe was tested to 1,000,000 cycles.
