1991 Raleigh mtn bike. Has center pull cantilever brakes. The front hardware is original and the straddle cable is about 100 mm long. The rear stuff is gone and I am putting on a new cable and shop gave me a similar piece but it is marked rear, B/82. So it is shorter. I have been told the longer cable gives u less mechanical advantage so the front has "less" grip than rear? Been riding awhile with no rear brakes and thought it was good to have both.
