hmmm, whats master cyl from. is that neccessary? could you just use the valve? you use metric gm calipers? need infos man, i work at napy so parts is cheap...
main question is what are the brackets from.
Its actually a Mastercylinder off of a Landcruiser I think 96 NON ABS....make shure its that it allows the correct pressure because it was already designed for rear disc brakes.
