Total Newbie Needs Help!

I just had a road bike technique clinic.

They told us use both with the same emphasis, and true, the front has 70% of the braking power while the back has 30%.
This can be compensated: In an emergency stop, to avoid going over, slide your butt behind the saddle. In the extreme, so far that you are completely behind your saddle. Really straigthen your arms, pushing yourself back from the drops.

Practice on a light decline (safety first, try a parking lot). Accelerate and come to a full stop. Start going faster and braking harder. Do it as fast and hard as you are comfortable. You can make your back wheel lock if you have the courage. I didn't.

I use my front brakes a bit more than rear. If I'm just coming to a routine stop (like a light I've had time to anticipate) I will use both equally... But for reducing speed decending, or for sudden braking, I favor my front brake (although I don't use it to the exclusion of the rear) because I have experienced rear-wheel skids when slowing significantly while descending. This happens because generally speaking when you're descending you have relatively more weight over the front wheel, and braking, especially suddenly, exacerbates this, further de-weighting the rear wheel and reducing rear-wheel traction. It's a little scary when it happens, especially if you're riding in traffic. In any case, it's a good idea to consciously slide back and make sure you're keeping your rear wheel weighted when braking suddenly or while braking on a descent.

I'm coming down with a cold, somewhat fevery and sore throat, so I apologize if that was a little hard to follow, I'm having trouble concentrating on anything right now.

ETA: the rear wheel skids I've experienced have happened when I've been using my brakes evenly (50/50). I think once it happened because the roads were wet/snowy (luckily I had *read* about rear-tire skids and somehow immediately knew what was happening, and was able to pull out of it almost as soon as it started by letting up on the rear brake -- but it's still scary because you feel that rear tire going out from under you). I've definitely become a lot more aware of where my weight is too. However, it's a myth that using your front brake more, or exclusively, will cause you to fly over your handlebars. It's better to use both for various reasons (even rim & brake wear, not overheating on long hills, plus of course two brakes gives you more stopping power than one brake), but it's not dangerous to use just the front brake as long as you keep your weight back.

Alpinerabbit gives you GREAT advice.

The front brake is your friend. Learn how to use it.

Why do people go flying over the handlebars? Because they never use their front brake, are afraid of it, then one day they HAVE to stop for some reason, so they jam the brakes. Their body and mind is not trained for that, they don't know how to react properly to the forces that are applied to them, and endo they go. Or maybe they'll just use the rear brake and fishtail as described above, endangering themselves but also whoever happens to be riding next to them.

Practice, practice, practice. When you use the front brake, shift your body weight to the back of the bike and know that your arms will have to absorb the shock. Eventually you would be able to use only your front brake, but it's still a good idea to use a combination of both.

+1 to rabbit, liza and grog.

On descents, you want your weight to the back of the bike anyhow, and braking safely is only part of the reason (handling is most of it).

I'm honestly not sure if there is such a thing as going over the handlebars. On motorcycles, it just plain doesn't happen, but it's a huge myth that many people believe. What there is on motorcycles is what's known as a "highside," where the rear wheel loses traction and then regains it, which causes the rear of the bike to buck into the air. Away from the racetrack, it usually happens when someone uses too MUCH rear brake, locks up the wheel, then panics and lets off the brake.

One exception to the rule of emphasizing the front brake is where traction is iffy (such as on gravel and very wet roads). There, you do want to emphasize the rear brake, since you're basically planning to skid, and a rear-wheel skid is much easier to control.

Oh, so I was totally wrong. Yes to the front braking!

Oy, something else to master.

YES YES YES, that's right and important, I forgot to mention that.

Wet roads (and gravel) are different.

Practice on those, too
