    Thanks for the awesome content! So so so much better than You Tubing and trying to find out the right answers.

    My question is this. Given that most of the breaking force (think sport or standard/naked bike) comes from the front brakes and in an emergency situation we want to load the from suspension quickly, should we use the rear brake? On the one hand the rear can add 5% braking power, but on the other hand it slows the loading of the front suspension thereby taking longer to get to the 95% of our braking power we need as quickly as possible.

    Bump. Hoping for a response.

    Interesting topic, any kind of deceleration should push your weight forward, but how much of a factor is the rear wheel squat… looking forward to a response as well.

    Thanks for the question Mark, and bump Murray.

    Yes, in theory…use the rear brake to help slow forward weight transfer. I write “in theory” because it’s just too cute to think we even have time to think in a true emergency. We will probably grab front and rear brake in the initial startled phase, and hopefully have enough brain power left over to modulate out of the rear as hard front braking unloads the rear.

    In these true emergencies, ABS really pays for itself because the locked rear just cycles in ABS and stays in line.

    In our studies, we don’t necessarily see the rear end “squatting” when rear brake is applied…we see that the rear caliper clamped onto the rear rotor acts as a rear-spring rebound control. As weight pitches forward, the rear brake doesn’t allow the rear springs to extend as quickly.

    As we can all guess: the rider who can manage front and rear braking grip the best, stops the shortest, all other things being equal. Educate your right foot, constantly adjusting brake pressure…less pressure as front-brake use builds, more pressure when front brake is used lightly. Thanks for your support of Champ U Mark and Murray….Nick I.
