Ok well i think i can help you out with the Brinks... as i just bought a disc locks thats brinks so calld "HIGH SECURITY" the modle is the r70, if this is that same as yours the get a strong hook and good strong tension wrench... this one goes against the gentle tension laws. Since the cylinder is spring loaded, the judgement is extremely difficult, but i found the picking techniuge, First add hard pressure and ocourse a strong tension wrench. And the pick used will be a medium hook. Ok its a trick and a half to learn but you basically use the storng tension and doing thins clearly dileniates when the pins have binded and sometimes you have to relise minimal tensions and eventually it pops. I dont know if this lock is what you have.. but if your used to easy masters...there really a pathetic lock.. get the R70 Disc lock.... its a good challenge

And if this not the lock post a pick or a modle number or a site reference giving us a good look at the lock, also it wouldnt hurt to show your picks.. the more we know the more we can help.. hope i helped buddy
