maintain the same speed you were traveling at before entering the curve.
|
|
|
be in a gear that will let you accelerate slightly in the curve.
|
|
|
brake in the curve to avoid to locking the wheels.
|
|
|
slightly exceed the posted speed limit for the curve, as this will help you keep control.
|
2.
Front brake limiting valves were used to:
|
reduce your speed so further braking or shifting is not required.
|
|
|
prevent overheating of the front tires.
|
|
|
reduce the chance of the front wheels skidding on slippery surfaces.
|
|
|
reduce exhaust emissions.
|

Stab braking:
|
involves applying the brakes all the way, and releasing them when wheels lock up.

|
|

|
8.
Total stopping distance equals:
|
Perception distance + reaction distance + braking distance
|
|
|
Reaction distance - following distance + braking distance
|
|
|
Braking distance + viewing distance
|
|
|
Perception distance + braking distance
|
9.
