Q:What will happen if you apply the brakes?A.the primary piston will strike the secondary piston B.the secondary piston will strike the end of the master cylinder C.no braking will take place

They're also called safety brakes. You'll notice that the pedal goes down much farther than usual but the front brakes still function.however your required stopping distance will increase.

Q:Hi, how can one devise an in flight regenerative braking system for a Jumbo Jet ? How much energy can be recovered and stored when the Jet descends from a cruising velocity of 555 mph at 40,000 feet and comes to rest on the ground at sea level ? Assume the empty weight is 178 tons, its human cargo weighs 45 tons and it carries 50 tons of fuel during the descent.This is a part of my assignment and I'am having difficulty doing it. All I can find on the internet is regenerative braking for auto-mobiles. I would really appreciate if someone could help me with this.Thanks a lot in advance! :)

Presumably, you could recover all the potential energy 200+ tons at 40,000 ft, plus the kinetic energy of the same mass moving at 555 mph. 178+95 = 273 tons 273 x 40,000 = 10.9 million ton-feet.

Q:380V 40A motor needs to come to dead stop. The stop time is not all that important, so there is some leeway here. I am going to use 3 semikron skkd rectifier units to convert the 3phase to DC to inject. Just need some design help. How much current and voltage will I need to inject? any other considerations I should be taking? Do I need capacitor blocks as well or can I do this without any resonance? from my understanding the capacitor bank make this even harder to calibrate?

Just rectifying the line voltage will give you way too much voltage. The load seen by the DC supply is essentially just the DC resistance of the windings. PS1 Why do you need to design this? Why not just buy a commercially available DC braking package? PS2 This manual gives an indication of what is involved, but this braking unit appears to provide better performance than a simple fixed-current system. downloads.eatoncanada.ca/download.

Q:I have an 05‘ Dodge Neon that I have put 18 low profile tires and wheels on. Just about every year I have to replace the front Rotors and Brake pads due to warping of the Rotors. I‘m sure this has something to do with lots of short trips and a lot of stopping and going. Also these wheels way considerably more than the stock wheels. Would it be beneficial to upgrade my brake system to a performance brake system, or can you just upgrade the rotors and pads and be fine?

It's hard to believe 18 aluminum wheels weigh more that the 14 stock steel wheels. Having said that, are you sure the wheel lug nuts aren't being overtightened? This will cause them to warp, just as hitting then in a car wash with the water wand if they are hot. It's only a matter of using a performance disc and pad set, but if I were you, I would try to find out what is really causing the warping.

Q:A) Pump the brakes to release a sticking brake shoeB) Check to make sure the parking brake is releasedC) Stop at the nearest service station to have the brake fluid checkedD) Shift to reverse and back up slightly to release a sticking brake shoe

Were the front brake discs (rotors) replaced? If not you might have warped rotors. It happens if the get overheated from excessive braking.

Q:Well it started 2 days ago, my cars brakes felt funny. When I brake, the break pedal went all the way down. Then I checked if the car had any brake fluid. It had a little bit. So I refill it again. Yesturday, It did the same thing, I notice the back passanger tire had brake fluid everywhere. I check the back of the brum of the and a little brake line was leaking the fluids. I replaced the little brake line no leak but Its still doing the same thing. When I push the break it take a long time to stop the car. What could be wrong?. Do I need to replace the brake pump?. Ideas?.

Did you bleed the brakes after you changed the brake line? because if not, then there is still air in the lines and you will have soft braking effects on the pedal

Q:I need to replace the front brake hoses and front brake pads on my 1997 BMW 320I, Is it worth doing myself or too much trouble and should I pay someone to do them?

a brake pipe spanner is needed to do the job when you weigh out the cost of the tool and also any seized pipes you may encounter doing the job i think it is best to find the mechanic

Q:My abs and sevice vehicle soon light keep coming on . Can anyone tell me what the problem is ? Also my brake pad are good and i went to good years a few week ago and they told me my rotor need to get done , does that have something to do with it also?Also could explain to me what is abs and how much it cost to get done ?

you have sensors behind the wheels and you might have a plug-in loose or corroded. a bad wheel bearing can cause it too.

Q:hello, i was wondering about a problem that i have with my brakes on a 95 Pontiac grand am se coupe. the problem started with the car kinda shaking whenever I would come to a stop. also the car kinda hesitated when stopping, kinda like it wasn‘t stopping to it‘s full capacity. This went on for a couple of days so i checked my brake fluid and saw that it was low, so i filled it up. Noticed about a week later that the same thing was going on, so i filled it up again and chalked it up to a a leaking brake fluid system and was content with filling it up every week. So i kept filling it up but noticed that the shaking would get worse and even happened when the brake cylinder was filled up to the top. Fast forward 2 months or so, i come home from college ( my car was sitting in the same spot for the whole 2 months), and decide to go to the store. read the additional comments to see the rest of the question

there's air in the lines. start at the back right tire and crack the brake line while a helper pumps the brake pedal to push all the air out. tighten the line, refill the fluid, and move onto the left rear tire and do the same. after that go to the front right tire, then the front left tire last. that will rid your brake lines of all the air. but it won't stop the leak. i can't help you there, you just gotta look for it. good luck:)

Q:for the last month my chevy has been beeping 30 times and displaying ‘service brake system‘ on the dash, every time I start it up.Does anyone know why?

could take a day or two depending on where you take it. the job would pay for 6-10 hours so about a day or two after the parts arrive
