Dani I'm not disputing your statement. what I'm asking is--if front-wheel only braking is maximal, why do the motorcycle guys say to use both brakes? Especially considering their maximum speeds are much higher than ours... It looks like I'm going to have to perform experiments. -Luigi |

When I'm braking heavily the rear wheel will actually be in the air part of the time. The rear brake does very little at maximum braking, other than give you something else to worry about. At more moderate stopping pressures the rear brake can contribute to braking proportionate to the weight that's on the rear tire. At the racetrack I never touch the rear brake. On the street, I use it occasionally when it's wet out and to hold my bike still at stop lights..that's about it. Cheers, Scott.. |

Especially considering their maximum speeds are much higher than ours... Because at normal braking rates, you can get good stopping power from the rears (on both bikes and motorcycles). It's only at near-maximal braking that the rears become useless. -- Dave Kerber Fight spam: remove the ns_ from the return address before replying! REAL programmers write self-modifying code. |

It's only at near-maximal braking that the rears become useless. The trouble is that a lot of people rely entirely on the rear brake since that's "adequate". Then a car pulls out directly in front of them and they have NO clue about how to stop fast. Either they use less than maximal braking or they go over the bars.

Thoughts on braking
I ride with some new-er mtn riders. They are scared ****less about "using the front brake and going over the bars." Lent one of them my C-dale last night for his night ride and he as much as told me he didn't use the front brake 'cause he didn't want to crash. Idiot. Oh well. Mike Don't judge them to harshly. I was scared ****less of the front brake for years too, mostly because I started riding as a child on a cheap huffy bike where the cheap caliper breaks barely worked properly on the cheap steel rims. And the few times I tried the front break, i did nearly go over the bars, and it scared me because I was riding on hard pavement in a townhouse complex. Using the front break *is* scary when you don't know what to expect or proper techinque. |
