Ski brakes

I have been skiing for 5 years and decided to finally get a pair for myself instead of renting. I bought some Fischer RC ones (82) through the fischer website because I got a company discount through my work. The skis look great, but when they were delivered there were no brakes attached the bindings. Is this normal? The picture on their webpage showed brakes, so I figured it would come with some. I just wanted to know if this is normal and how I can find a pair of brakes that are compatible. Once I find the correct width are brakes a universal fit, or do different brands have different ways of connecting them?  

Here is the link I bought them from www.fischersports.com/us_en/rc-one-82-gt-twin-powerrail-1313?c=5331
