It's more then that. At least for motorcycles, and depending on the geometry of the bike, your front represents 70% of your total braking capability on a heavy cruiser vs 90% of your total braking capability on a sports bike. https://www.youtube.com/watch?v=jDGvzy038Eo&t=59s https://www.youtube.com/watch?v=jDGvzy038Eo&t=59s <-- demonstrates it rather clearly. From 80kph, braking distances are: Rear brake only: 40m (131 ft) Front brake only: 17m ( 55 ft) Combined: 13m ( 42 ft) The issue that braking capability is a function of friction of the tires against the road surface, which is in turn a function of force pushing the tire into the ground. When you begin to decelerate there's a weight transfer to the front tires, increasing the weight on the front and decreasing the weight on the rear. In other words, increasing the effectiveness of the brakes in the front and decreasing the effectiveness of the brakes in the rear. In the extremes with (im)proper body position, you can lift the rear tire clear off the ground: https://www.youtube.com/watch?v=2BqCJgTpEf0 https://www.youtube.com/watch?v=2BqCJgTpEf0 So someone suggesting that you remove your most powerful brakes seems... odd?
