A real brain teaser for those of massive knowledge about trailers.
I have a Rapide roller trailer that I no longer need that I am getting rid of. It started life as an R2B49 but has been extended to carry a 7m and had a 2nd axle fitted. (but still plated at original spec

)
It tows ok and will go back to original size easily if needed
BUT it has mechanical disc brakes on both axles.
Rapide are now owned by Dixon Bate so you can guess where this thread is going. Spares and info are impossible to get.
The brake parts are ok for now but if I am going to move it on to someone I'd like to be able to tell them they can get spares. I doubt the pads and discs were bespoke so does anyone know what parts Rapide might have used for their disc brakes.
