Предната спирачка има по-голяма спираща сила. Чел съм го в "Mountain Bike Like Champion" на Ned Overend. Цитирам :

Ideally, you'll be able to do most braking with the front wheel. It has the most stopping power, especially when you can get your weight back and drive that tire into the ground. But be carefull. When using the front brake hard, you need to keep your body vertical. Don't brake hard in a turn, or the result could very well be a front-wheel washout and a heavy crash. Get on the brake when you're in proper alignment on a smooth patch, then get off as you turn or chatter through rough or loose sections.
The rear brake is less effective than the front, but it's still useful.


И т.н.... Има още доста по темата ... Това отговаря и на въпроса защо производителите ако решат да сложат само една дискова спирачка винаги избират да е предната.
