I wonder what flare is used on the 2003 mgtf (non abs) I think that the brake pipes I have removed are DIN/ISO Bubble Flare
These are the ones I removed.
I sort of think this because they seem flat on the base of the flare and domed on the top>
the flare kit I have borrowed seems to make the base tapered and to double flare, the centre you press in makes it more trumpet like.
