rear brake line and fitting sizes

Hi guys,

can anyone provide me with the specs for the rear brake line fitting to the rubber brake line, as well as the diameter of the line once it tapers.

I need to replace my rear brake line from the master cylindar to the rubber flex hose and I dont know the diameter and thread of that fitting.

Once I pull it off chances are it wont be usable again.


Thanks

Re: rear brake line and fitting sizes

i "think" its 12mm 1.0 the hardline is 6mm. You can use 1/4, but the fitting nuts may have too small of an inner bore depending on what you get

the front fitting on the prop valve is 14mm 1.5

not sure what you mean by the lines size after the taper. there is no taper.
