At Citromobile earlier this month in in Vijfhuizen, The Netherlands, Ramon Arias de Bles showed off the the disc brake conversion he does to H Vans.
The modification is becoming popular – the HY Van shown here, two years into a ground up restoration, was done for Citroenvie member Erik DeWidt and will be shipped to him in Maryland once the next phase of the project, installing a modern Volvo engine and a Peugeot five speed transmission, is complete.
We have written about Ramon’s engineering efforts before in Citroenvie. (https://citroenvie.com/?s=Ramon). Ramon did the conversion of my H Van to disc brakes when I had it in Europe 2017. A very elegant bit of engineering and the difference in braking power was measurably better!
Since Citroën chose to utilize the same front drum brake set-up as in the Traction Avant 15-6 (6 cylinder engine) in the H Van, it is possible to fit modern disc brakes in that model. We hope to show the progress of a Traction 15-6 conversion in a future article.
We also look forward to publishing a road test of Erik’s HY Van when the engine and gearbox conversion is completed. Ramon and Erik will need to fit seat belts this one!
In the meantime, here is an update from Ramon on the conversions; the components used and the cost:
We have updated our brakes with common parts that can be bought in any cars shop that sells modern Citroën parts.
HY disc brakes are made partly of Citroën C5
The HY wheel technique is based on the technique of the Traction Avant 15CV. So our disc-brake design for the HY we changed so we also now have a disc brake solution for the TA 15CV. For the 2 designs, there is no need to change the axles. Bearings stay original, we just have adapted the bearing housing and make a new hub.
The HY conversions parts are; Hub, Fusee, Handbrake cable, Brake tube, and Disc. Cost is: 2.765 euro’s for export. Within
Parts assembled without
The 15-6 Traction Avant conversion parts are; Hub, Fusee, Brake tube, Disc. Cost is: 2.755 euro’s for export. Within
Parts assembled without
A set of C5 Calipers cost an additional 320
(*) we need original parts back for stock or we need to charge
Our new challenge is to design brakes for 4 cylinder Traction Avants. If there is interest for this from Citroënvie readers I would like to know. Please contact me about this or any other additional information
