I think those are the ones...
As far as different rim brake systems, there are 3 main types, and several offshoots of each type.
The original type is the side pull caliper brakes where the caliper is mounted to a center brace abover the wheel, these are probalby the least effective since there's a lot of flexing that the calipers can do since there are a lot of turns and bends in each caliper half and the scissor mechanism, they tend to absorb most your brake pull by flexing a lot.
Then later on the V brakes (cantilever type) were designed and started showing up on BMX bikes in the early 80's. these brakes offered considerably better stopping power since each lever was on it's own mount on each side of the wheel and connected by a common cable with the brake cable pulling on this center cable, the feel was more direct and positive since the arms were more straight and had less curves or bends in them which for the most part eliminated the flexing that was common to the original side pull design, but still took a lot of lever pull effort compared to the third design..
The thrid design is the linear pull design which is very similar to the cantilever design since each lever arm is on it's own pivot on each side of the wheel, but this design, the center cable is eliminated and the single cable comes in from one side and connects to the other side so it has better leverage at the brake handle so it offers more stopping power with little or no flexing of the arms, and with the longer arms there's slightly more lever movement but less pull effort needed, these are the most common on most mountainbikes since they offer the best overall stopping power.
