late reply but - you just shot yourself in the foot, and the bullet will bite you in the butt too, you are never supposed to install used brake pipes, get new ones - you can find them easily, if you cannot get a new set crimped from extreme pressure brake pipe, You could have gone to a toyota showroom parts department for them..
sometimes - PW really amazes me. This also reminded me of a used parts shop in Magazine like Karachi selling "used jenyan EFI fuel filter" for older toyotas - complete with imported junk and crap in them.
btw I have used made in Lalukhet Karachi brake pipes and they work, just make sure that the shop crimping them have a proper hydraulic swage tool.
