1. Braking Systems While most motorcycles have a front brake lever to apply
the front brake and a rear brake pedal to apply the rear
brake, braking systems can differ between models. Check
your owner's manual for variations, which may be one of
the common setups shown here.
With Combined or Linked brakes, braking force is applied
to both wheels when either control is used. The degree of
braking force provided by each brake varies by design.
With Integrated brakes, pressing the rear brake pedal also
applies some braking force to the front brake.
Anti-lock brakes, also called ABS, keep the wheels from
locking or skidding when too much brake pressure is ap-
plied for surface conditions.
2. Emergency Stop
in a Straight Line Making an emergency stop is an important skill. Practice
often in a safe area. Use lower speeds and less than
maximum brake pressure when developing your skill. Start
your practice with straight-line stops.
The best way to achieve the shortest braking distance is
to apply maximum brake pressure to front and rear brakes
simultaneously without skidding either wheel. Squeeze
the clutch lever and use the brake controls at the same
time. Keep your body centered and look ahead. Squeeze
your legs against the gas tank to help keep from sliding
forward. Adjust your braking pressure as the weight of the
motorcycle transfers forward by using less pressure on the
rear brake pedal and more pressure on the front brake
lever.
The ability to use the brakes fully without producing a skid
is called threshold braking. This kind of braking takes a
special feel for the controls. It is important to squeeze,
not grab, the front brake lever and press, not jab, the rear
brake pedal. Practice often in a safe area. Remember that
surface conditions may affect how much pressure you can

3. Emergency Stop in a Curve use, and you want to be ready to adjust the pressure for best results. Making an emergency stop in a curve requires effective use of available traction for both leaning and braking. This means you should generally use less brake pressure in a curve than when braking in a straight line. Basically, you have two choices: One is to straighten up first and make a quick stop in a straight line. The other is to apply some brake pressure while leaned and increase brake pressure as you straighten up. To straighten up first, you must have enough space to complete the stop. If road and traffic conditions permit, straighten the motorcycle first and then square the handle- bars (center the steering) before the brakes are applied. To apply brake pressure while leaned, apply and adjust the brakes progressively. As your lean angle is reduced, apply more brake pressure. It is best to have the motorcycle straight up with the handlebars squared at the end of a stop.

  1. Front Tire Skid Using too much front brake pressure can produce a skid. To keep from skidding, use the front brake lever with a smooth squeeze. If the front brake lever is grabbed before weight transfers forward and down, the wheel can stop turning and the front tire will skid. The result is a sudden loss of control. If a front-tire skid occurs, you must release the front brake lever to get the front wheel rolling again. Then apply the brake again as needed. Improper use of the front brake could cause a fall.
  2. Rear Tire Skid When slowing quickly, weight increases on the front tire and lightens on the rear tire. You have to adjust rear brake pressure so the rear tire does not skid.

If the initial swerve is in the same direction as your lean, you need more lean angle. If the swerve is opposite the direction of your lean, a much greater lean angle will be needed to recover after the initial swerve.

  1. Brake or Swerve The decision whether to brake first or swerve first in an emergency is critical. Give yourself a large time-and-space safety margin so you have time to respond by either braking or swerving. This takes excellent Search skills so you can Evaluate and use your escape options. Keep in mind an escape option can change quickly if the hazard is moving. For example, a car pulling out in front of you could continue in its path, or stop. If you brake without enough distance to stop, you crash at a reduced speed. If you swerve without slowing and do not have enough space to avoid the hazard, you crash at your original speed. While riding on the highway, cargo from a truck ahead of you begins to fall into your lane. Do you brake first, or swerve first to avoid the debris? Like most brake or swerve decisions, there is no absolute "right" answer, and your decision will depend on circum- stances and include your judgment and riding skills. Since the debris could be moving in different directions as it falls from the truck, braking first may give you more time to choose your best escape path, and illuminating your brake light will warn vehicles behind you of the debris. On the other hand, swerving first could more quickly remove you from the path of the debris, and could prevent you from being rear-ended by a vehicle behind you. 10.
