>>1317069>They needed to be linear to work with suspension. I stand by what I posted.You're about to get schooled you stupid little shit.
The cantilever brakes pictured here work fine with suspension. However, they had a decreasing inward pull on the brake pads the more they were squeezed. This meant there was not a linear relationship between how far or hard you pulled on the brake levers and the amount of force you were directing inward towards the rims. This is very simple geometry. By increasing the length of the length of the brake arms the brake pad mounted on and running the cable perpendicular, you did get a much more linear relationship that both gave you far more leverage over the pads and much closer to "linear" modulation. Ergo, V-brakes were also known as "Linear" brakes when they first became widely available. Their modulation is fantastic as is their power.
There are also advantages to hydraulic disc brakes. They're 100% linear in the above regard and as other anons have pointed out, they're better for carbon rims and muddy conditions. However, a properly set up pair of high end V-brakes set on a perfectly true wheel (which was nearly always the case for the most OCD among us), felt absolutely amazing and better than discs. Hydraulic discs are great though.
