Describe the proper breaking technique when going down along steep downgrade.

Remember the use of brakes on a long and or steep down grade is only a supplement to the braking effect of the engine. Once it is in the proper low gear the following are the breaking techniques. Apply the brakes just hard enough to feel a definite slowdown. When your speed has been reduced to approx five mph below your safe speed release the brakes.When your speed has increased to your safe speed repeat step one and two FOR EXAMPLE IF YOUR SAFE SPEED IS 40 MPH YOU WOULD NOT APPLY THE BREAKS UNTIL IT REACHES 40 AND KNOW YOU APPLY THE BRAKES HARD ENOUGH TO GRADUALLY REDUCE YOUR SPEED TO 35 MPH AND THEN RELEASE THE BRAKES. REPEAT THIS OFTEN UNTIL YOU REACHED THE END OF THE DOWNGRADE.

BEFORE STARTING DOWN HILL

SLOW DOWN AND SHIFT DOWN A SPEED SO THAT YOU CAN CONTROL WITHOUT USING THE BRAKE HARD. Otherwise the brakes can overheat and lose their braking power.

What factors determine your selection of a safe speed when going down a long steep downgrade.

Select the right gear before starting down the grade. Shift the transmission to a low gear before starting down the grade . Do not try to downshift after your speed has already been built up. You will not be able to shift into allow gear with older trucks a good rule is to for choosing gears use the same gear going down the hill is when you started up the hill. New trucks have low friction parts and streamlined shapes for fuel economy they also have more powerful engines That means they can go up higher hills in higher gears and have less friction and air drag going downa hill that would require to go up the hill Modern drivers may have to use lower gears going down a hill than would required to go up the hill . You should know what is good for your vehicle.

IF THIS HAPPENS MAY SKID OUT OF CONTROL#2 DO NOT TURN AS NEEDED TO CLEAR WHATS EVER IN YOUR WAY. THE MORE SHARPLY YOU TURN THE GREATER THE CHANCE OF A SKID OR ROLLOVER.#3 BE PREPARED TO COUNTER STEER THAT IS TO TURN THE WHEEL THE OTHER DIRECTION,ONCE EVERYTHING IS CLEARED IN YOU PATH.
