Car stalls when I hit the brakes?

my car is a 1993 Pontiac Grand prix. If I keep my foot on the brake and try to start the car the engine will start but almost as soon as I take my foot off the brake the car will stall when I put it into gear. Its not something that happens all the time. My car has ABS and when I realize my foot from the brake their will be like a plastic sound coming from the booster but it will only happen if I start the car with my foot on the brake and when I take my foot off the brake it will make that plastic sound. The ABS will also make that sound if the system is activated. The engine has 179K miles on it but it has new gaskets in the upper intake all new vacuum lines and I also replaced the plugs with Platinum plugs. the car had this problem before I changed anything. I maintain the car like a new car so even with 179k the car still looks new even up close it also runs and drives great but the only problem I have is with it stalling sometimes. the booster holds vacuum and my brakes are responsive and they don't fade or anything. I don't have any ABS lights or check engine lights I checked all my fuses and they are good the ABS system it self works fine as I test it every now and then if I am driving on a wet road. the engine can pull 20 pounds of vacuum at idle and almost 32 at speed.

the brake booster is one cause but the transmission is another. the torque converter is a lock up type and if this is your problem then the control solenoid or the circuit to that is at fault.

the brake booster leaking or bad
You say your booster makes a plastic sound but I don't know what a plastic sound sounds like. When you start your car with your foot on the brake, if the booster is OK the pedal should sink towards the floor slightly. If it doesn't, the booster has a leaky diaphragm which just might be what's causing your problem..
If it's not your booster that has gone bad, try checking your throttle body's idle. When you place a car in drive it places a bit more of a load on the engine. If your idle is too low, this may be too much for the engine and it will cuase it to stall. It's a simple fix. Just need a screwdriver. Hope this helps.

Apparently I need my car aligned. Would that cause a shaking/rattling noise in the front when I drive?

I went to get my front brakes changed recently and was told I needed an alignment badly and a new axle and tie rods on the front. Which of these things would cause the front of my car to shake when I'm driving fast on the freeway? And if I can't afford to do them all at once, which would be best to do first? Thanks!

Tire balance! The shaking is what killed your tie rods and ball joints in the first place.



If the shaking only happens during braking, it's your rotors.



Whatever it is get it fixed all at once, beg borrow steal whatever it takes. You will probably pay less in labor that way, and your saftey should be first priority.

probably all of it if u trust the place.

these problems can easily damage your tires n u don want to get new tires, do u
what year is your car, mileage and condition of it also, depending on the problem it may be time to just get a new car, i mean why keeping putting money into somethinig that may break down again in a fe months, my mom kept doing that with her car, i said mom u could be using that money as a down paymenht for something better. moral of this story is that she took my advice and now has a 07 chevy cobalt, she has had it for almost a year and has saved herself time and trouble.



if your car is fairly new, then maybe u want to invest in it, its all up to you!

Why do my Car Brakes Squeal?

Ok so I have a 2002 honda Civic Lx that I recently bought like about 4 months ago. When I bought it the brakes were perfectly fine, but I guess I was told that it needed new brakes. So my dad went to go change them for %26quot;new%26quot; brakes. Ever since, my front disk brakes began to squeal after a few times of braking when I'm driving (No I am not a reckless driver so I know how to drive and brake properly). My dad went back to see what's wrong and they told him that its just the kind of metal that is used on the brakes, that they make that noise but work perfectly fine.





So is it just the the kind of metal used for the disk or brake pad that's the reason for all this screeching or is it something else that I am not aware of?
Why do my Car Brakes Squeal?
Rock Star has it right. I use %26quot;Disc Brake Quiet%26quot;, in both a liquid application and a spray. you pull the pads, apply the stuff to the contact points on the pad (on the back - do not use it on the points where it touches the top of the caliper!), and reassemble.



The squealing is a vibration that occurs at the pad, and is transmitted up the caliper. The disc brake quiet acts as a vibration dampener to prevent the pad from chattering excessively.



Is it %26quot;the kind of metal%26quot;? Yes and no - certain types of pads that are designed to resist brake fade seem to have a tendency to develop a squeal, but from my experience, it can be a combination of the pad material, the rotor condition, and just plain luck.

at the counter of almost every auto parts store they have small 1 ounce tubes of %26quot;Squeal Stop%26quot;.

Place a little on the metal of the brake pad (Backs) reassemble

By BY squeal
usually cuz there bad or because you have break dust. by brake dust cleaner and spray all of it and then drive to 60mph and slam on breaks. should be straight. or just get brakes inspected for free at any good brake shop.

When your car is shaking when you brake and u just changed the brake pads what do u need to do?

My car shakes when I brake and I just changed the brake pads about 6 months ago and I would like to know if I now need to change the rotors or there is something else I will need to do
When your car is shaking when you brake and u just changed the brake pads what do u need to do?
The rotors would be the first thing to check. It could be something else related to the brakes, given you don't get any shaking other than when you apply the brakes.

sounds like you need to have the rotors turned (if they haven't been already) or you need new rotors.

sometimes pad slapping them (just putting pads on) ends up creating a rotor warp situation.

sounds like that happened.

good luck!




This just happened to me and I actually had to have them shaved down. They were warped. Might be your problem too. Have a mechanic check it out.
maybe shocks or rack and pinnion
your rotors are warped. depending on the thickness of the rotor, you will either have to resurface them or have them replaced. if you resurface them, you will make them thinner and they'll warp again sometime down the road. if you get them replaced, they will be thick again and won't warp for a while.

Is it bad to drive an automatic car the manual way?

My husband keeps driving my automatic car the manual way.He thinks he is saving gas and saving the brakes (I need to change the brakes but can't do it for at least another month) My car is not manual so I don't think it will save me any gas, but what about my brakes? Thank you!
Is it bad to drive an automatic car the manual way?
Heheheheh...my wife gets annoyed with me when I use the manu-matic in my Mazda (alliteration FTW) too.



Except I usually only use mine to save gas. It doesn't go into 6th by itself until it's above 42mph. If I'm doing 40 on fairly level ground I click it over to the manual gate and drop it to 6th.



The only time I shift down with it in normal driving is when I have been in the mountains on a long downhill section
Is it bad to drive an automatic car the manual way?
Well you can shift it from the low gear to higher ones but its better to leave it in drive for the transmission and if you down shift like that its real bad while your moving its not the same as a manual transmission the inside is different.
Brakes are a lot cheaper than transmissions. I don't recommend what he is doing except under certain circumstances, such as going downhill.
Yeah if anything it uses more gas, their higher the rpms the more fuel needs to be injected.. theirs nothing that saves fuel.. if you wanna save fuel stay light on the pedal..
I would say he is not saving gas, most likely using more. Modern automatic transmissions are pretty efficient and smart. Some can actually learn your driving style to make things more efficient. Shifting one manually will confuse it so even when you drive it would be as efficient as it could be. As long as he is not driving aggressively he is probably not hurting the transmission. He may be saving a little on the brakes but not enough to make it worth the trouble in typical city traffic.
Bad? Maybe. Pointless? Absolutely.



Believe it or not your cars computer controlled transmission is smarter than your husband. It knows the perfect time to shift and will hit it with split-second precision. Make a mistake shifting manually and you could have a repair bill of several thousand dollars.
It's certainly not %26quot;bad%26quot; for the car, but I doubt he's saving much gas, if any.



If he's downshifting when he drives down steep hills, however, then, yes, it is giving the brakes a rest. In low gears, the wheels can only spin so quickly at a certain RPM, so by downshifting down hills you can delegate some of the braking to your engine instead of your brake pads. This safe driving technique is recommended for all long hills with all cars.
only on very steep hills would i downshift it that way other than that its a waste just wears out shifter parts and besides brakes around 150$ or trans 2000-3000$ unless he has money to burn tell him to knock it off its your car let him do it to his

How much should I pay to have a mechanic change the my car's front brake pads?

I have already bought new break pads from someone, so I only should pay to have them changed. I live in Los Angeles by the way. Please give me an appoximate of what would be reasonable. I'm a student, low on cash.

Thank you.

You did a no,no. It would be the same as bringing your own steak to the resturant and asking them to cook it for you. Never bring your parts to a mech and ask them to install them. Now you will pay around $75 to have them put on.
How much should I pay to have a mechanic change the my car's front brake pads?
They should be able to do it in under an hour, but they will also charge you for shop supplies and will probably come up with some other things that they will try to charge you for, the rotors may need to be turned as well, if they are badly scored they may need to be replaced, I would borrow some tools if you don't have them already and do it yourself, it's an easy job and then you know you won't get screwed by some mechanic that is trying to charge you for work that doesn't need to be done.



Sorry if I offended any repair shops, I just don't trust them and do all of my own work unless it's under warranty.
Shop around. One guy may do it for a case of beer whereas another wants a million. That is free enterprize.
To do the job right the rotors need turned and the pads installed, Midas charges $79.95 for the job and thats about the cheapest around, it would be cheaper for you if you had a buddy who could do it for you and buy him a case of beer.
grab a friends tools and do it yourself,it's unbelievable to me that anyone ever gets a garage to do such simple jobs
First off it's really best to change the rotors when changing the pads unless the pads were evenly worn and how damaged at all.Also the rotors could be burnt or unevenly warn so it's best to have a mechanic perform a free brake check on that vehicle.

The labour really isn't any different in price if the pads and rotors are replaced at the same time and really it should be more then 45 mins to 1 hr of labour cost tops.





Hope that helps and best of luck.By the way I'd not say anything about changing the pads etc until you have the free test performed and hear from from the mechanic.
I charge $25 per wheel + parts.
Like $50 each wheel

When driving my automatic car; it sometimes slows down by itself as if I am changing gears. What's wrong?

I drive an automatic 2001 VW Golf GL. When on the road, my car sometimes does this thing where it feels like I am shifting gears (as if I were driving a stick shift) or driving on neutral (which I am not). It happens when I'm driving it, not when I'm in the process of braking. Does any one know what can be wrong with it? Thank you.

Could be transmission gears slipping?
