The power brake system relies on vacuum or hydraulic pressure generated by the engine. If the engine fails, the power brake assist will typically only function for a limited number of brake applications, as the stored vacuum or pressure will deplete quickly. After that, the brakes can still be used, but they will require significantly more effort to operate since you will be relying on the manual braking system.

Would a bad alternator cause a car to die while driving?
If the alternator fails, it is no longer keeping the battery charged and your engine is running on nothing but battery power. Once the battery runs down, your engine will no longer run.
How does a hybrid car gets its power?
a hybrid is just that, a hybrid. it has a generator and a petroleum engine. the petrol powered engine starts and as it works it charges the electric one. when you brake this charges the electric one even more. once you drive at a constant speed (freeway) the electric engine will engage and thus save fuel.
Hot to burn out in a front wheel drive car?
On wet pavement, e-brake on- dump the clutch(manual)/ power brake (auto) release e-brake once the tires are spinning at a good speed.
What should you do if your engine suddenly fails?
If your engine suddenly fails, remain calm and maintain control of the vehicle. Safely steer to the side of the road or a safe area, turn on your hazard lights, and come to a complete stop. Once stopped, assess the situation and attempt to restart the engine. If it doesn't start, call for roadside assistance or emergency services for help.
2003 dodge neon brakes are hard when engine off but soft with engine on?
because the hydraulic system pumps are running when the engine is on (power brakes), assisting you in applying the brakes. if your car did not have a brake assist pump, the pedal would always be difficult to press. Actually, there is no "hydraulic system pump", but a vacuum assist device. It is that large, round, metal thing that the master brake cylinder is attached to. Obviously, it operates on the engine's vacuum while the engine is running. With the engine off, there is no vacuum, and therefore no assist. There is a big, rubber diaphragm inside it, which is operated on by the engine vacuum. Pushing down on the brake pedal opens up the vacuum. When you let up on the brake pedal, springs return it to the original position. Occasionally they develope small leaks in the diaphragm, and have to be replaced. I have done this once as a "shade-tree" mechanic, who was trained in the U.S. Air Force. It is not an easy job.
How do you burnout in an automatic?
ok just throw it in drive and hold the brake all the way to the floor then rev the motor till bout 3000 rpm depends on engine and were red line is but then ease of the brake slowly wile pushing on the gas more and once the tires are spinnig and smoke ing then let off brake completely and once off the brake punch the trottle and drive away
What causes intrument gauge and lights to quit power windows quit headlight sensor quit check engine light is on center brake lights don't work and happened all at once while car was running down the?
it sounds to me like you need to change your alternator ?
Does a 95 Oldsmobile cutlass ciera with a 3300 v-6 need the alternator to start it?
Yes, a 1995 Oldsmobile Cutlass Ciera with a 3.3L V6 engine needs a functioning alternator to start. The alternator charges the battery while the engine is running, but if the battery is fully charged, the car can start without the alternator working. However, once the engine is running, it will rely on the alternator for electrical power and to keep the battery charged. If the alternator fails while driving, the vehicle may eventually lose power and stall.
Why is power steering hard at slow speeds?
Low on power steering fluid ... check it, and all your engine fluid levels, at least once a week.
What suppliesthe ae2100d3 fadec with power until engine rpm is sufficient for the alternator stator to take control?
The FADEC already has power prior to engine start. In fact it controls the entire start sequence. It receives power under normal starting conditions via an ECBU ; the acft will have power from either an external source, the APU, or an operating engine. The alternator stator provides power to the FADEC once the engine reaches 10% NG. This way the engine is entirely self sustaining once started and during the majority of start sequence. Should the alternator stators fail, power is then given from the ECBU again (28v DC power source).
Why won't a car start without it's batteries?
The starter needs power to crank the engine to get it running. Once the engine is running however, the alternator generates enough power to keep it running. But with no reserved power (a battery) the car cannot turn over.
Can high revving cause damage to engine I was driving my car really fast and on 160kmh I did not hear my engine is in red line I felt like car started to brake on there on then I saw I passed red.?
aaah yes of course high revving will cause damage to the engine.. that's what the red-line is for. once you get to the red line the engine will automatically reduce the fuel input to protect the engine, probably will just be a smooth interruption of power.. unless its electronically limited, which i don;t know how that works
