What is trail braking?

I've heard it talked about it magazines and whatnot. Just curious to what exactly it is. I have an idea but i wouldn't mind knowing for sure. thanks

Trail braking is continuing to brake after turn-in as opposed to braking only in a straight line.

If you're going to start practicing this, be very careful. It's not a beginner technique.

Geo has forgotten more than I know, but I thought I'd add a little. If you're braking in a straight line, taking your foot off the brake and THEN turning in, you're not using 100% of the front tires' grip all of the time. Trail braking like a master is using all of the tires' grip all of the time. As you start to release brake pedal pressure you're turning the wheel. In terms of grip, as soon as you're only using 99% of the tires' grip for braking, you begin to use the remaining 1% of grip for turn-in, until you're using 100% of the grip for cornering. Not only is it more fluid and more efficient (in terms of maximising tire use), you're also carrying more speed into the corner since you can delay the beginning of the braking zone (since you're braking into the corner).

Yeah, thats what I thought it was. Sounds somewhat difficult and no i don't plan on practicing in my car on the streets haha. Just was curious and wanted to know exactly. You know what they say, knowledge is power. thanks

In terms of maximizing grip, search the net for information on the friction circle. The friction circle is the theoretical limit of the tires grip and you trade forward (or reverse, i.e. braking) acceleration for lateral acceleration in a theoretically smooth fashion.

If you read someone saying a plot outside the circle means a car has exceeded it's grip, move on to another source because that's wrong. It means the theoretical circle is too small. Exceeding the car's grip would move the plot inside the friction circle.
