Brake pipe

[Pops]

Bought replacement Flexi pipes last year but never fitted them because the first one I tried to open was seized, I'm sure the metal pipe is going to break.
So, now I'm thinking of getting a break pipe flaring kit so that I can replace any pipes that are needed, does anyone know what size of pipe and union's is used on the mk1

[Steve]

unions are m10x1 as far as I remember.

Thanks Steve, found some flaring tools on temu, good prices but not sure if they're the size needed
