if the emergency brake and pedal brakes of an automobile failed how would I stop my automobile traveling at 50

Answer 1

use the other recommendations. downshifting is good. Just remember that the emergency brake locks, and if applied hard enough will lock the rear wheels causing a nasty skid and a possible rollover. if using the e- brake is your only option then put the vehicle in neutral and SLOWLY apply the e- brake until the vehicle starts to slow. Downshifting is the best option if you lose the hydraulic(brake pedal) brakes.

Answer 2

If driving a manual, downshift slowly from highest gear to the lowest gear,like 5,4,3,2,1. No gas for each down shift. this is call an engine breaks. when at the lowest gear, turn off the engine and leave the car in the 1st gear or Reverse, preventing it from rolling.

If it's an auto, downshift from D to l until you reach the lowest gear, turn off the engine.
If all is failed I guess you have to carefully(for your safety and others) crash your car into a guardrail or a tree, or other cars or even in a ditch.

1. Warn other drivers and pedestrians. Turn your hazard lights on, and honk your horn to make others aware that there is a problem. While they may not be able to figure out what the problem it is, a warning should cause most people to proceed with caution and pay attention to what your vehicle is doing.

2. Pump your brakes. Pumping your brakes several times may rebuild enough pressure in the braking system for you to stop. This may take a while, so keep trying. You should do this even if your car is equipped with ABS as the ABS is only activated when your car is braking too hard, which won't be the problem if your brakes have failed.

3. Shift into low gear. If you have a manual transmission, downshift quickly. You may not be able to downshift directly into first or second gear at high speeds, but go into the lowest gear you can, and try to downshift again once the vehicle slows a bit. With a manual transmission you can possibly stop the car very quickly by slamming it into reverse; according to one report, it spins the drive wheels in reverse momentarily, then the entire transmission fell into the street as the car stopped! If you have an automatic transmission, shift into low range (generally labeled as “1” on the shifting mechanism). Again, if you can’t go directly into the lowest range, try gradually shifting down.

4. Use friction to slow your vehicle. Driving through gravel or dirt (such as you might find right off the side of the road) can slow your vehicle considerably.
Use guardrails to slow your vehicle. Cement dividers are built pear-shaped so that contact is made with the wheels, not with the precious metal and paint of your automobile. Applying friction to the rubber on your wheels will slow the car considerably without harming other portions of your vehicle.
Use terrain to your advantage. Try to seek out inclines that you can go up.
Small trees and shrubbery will slow your vehicle when all else fails. Try to put your vehicle through the center of a line of shrubs or saplings, being careful not to pick a tree that is too heavy for your car to go through.
Hit the back of another car. While obviously not a first choice, it can slow your vehicle. If you’re going to do so, try to warn the driver in front of you by honking your horn. Try to strike a vehicle that is traveling at about the same speed as yours (hitting a slow-moving or parked car will stop you, but the deceleration will be quick and extreme) and attempt to make impact squarely on the back of the vehicle. Glancing blows will likely send both vehicles out of control.

5. Look for a safe spot to pull over (or to crash). Scan the road ahead for a safe area to pull over once you’re able to come to a stop. If you’re not able to bring the vehicle to a complete stop, look for open spaces that you can coast across without hitting anything.
If the safest spot to "crash land" your vehicle requires you to jump a curb, extra caution must be taken. Even with power steering, the cars' initial reaction will be to rip the steering wheel from your hands, bounce from the curb and back into traffic. It is imperative that you grip the steering wheel in a firm manner and angle your car deep enough into the curb so that it will go up and over, yet shallow enough so that you don't turn the car completely and lose control in a spin.

Answer 4

Downshift to apply engine compression as a brake of types, attempt pumping the brakes to work out in case you may some thing out of them. If a crash isn't avoidable, attempt sliding down the guard rail or protecting wall if one is obtainable as a replace of hitting yet another vehicle or table certain merchandise like a tree. in case you have room adequate to coast, lay on the horn to warn others and coast to a give up, steer off the line, and as quickly as you're stopped positioned it in park to hold it in place whilst you dial for help on your cellular telephone.

Answer 5

Down shift. Don't put the car directly into first gear. This can seriously hurt your engine. Down shift gear by gear. If it is in 4, go down to 3, wait a few seconds, then go down to 2, reapeat into 1st gear.
If it's a total emergency where you must stop immediately, put the car in first and hold on because it will throw you forward as the engine winds down.

Answer 6

Shift into lower gear and take your foot off the gas. THe engine will slow the car down. Work your way down the gears to the lowest and then turn off the engine. The engine should bring your car to a stop.

Answer 7

This is a common sense question, and it depends on how fast you need to stop.
if your just rolling down a highway with no urgency, you can do as suggested gear down, and decelerate until you coast to a stop.
if your headed over a cliff, or some other emergancy where you need to stop more quickly, then several things will need to be considered depending on availability. Again gear down, and decelerate.
1'st your auto isn't worth your life and it may have to be sacrificed to save yours (wreck it)
you may need to use the side of a cliff, trees, other autos, anything that will help you to stop.

Answer 8

if you have P N R D 3 2 1 then put it in 1, that may help, if not just go to the side take your leg off the gas and it will speed down.
