And that is where exactly i don't feel comfortable , the car jerking , RPM shooting high even though its just a second or more. In my driving style the car never jerks and the engine RPM is kept in check , and so overall i feel passengers will have a pleasant journey in my driving style. Though i agree in panic braking engine braking will come in handy. But our basic instinct atleast mine is to use both the clutch and brake simultaneously in a panic situation.

Sorry for the long post. I feel there are a lot of confusion regarding engine braking.

Engine Braking and Engine Aided Braking are entirely different.

Engine Aided Braking is what we should do in normal driving conditions, when your brakes are in working condition. Like, when we are moving at 120 or so and need to slow down or stop, just apply the brake as per the situation requires, till you reach the minimum speed in the particular gear you are in. (This way the Engine complements the brakes to slow down your car more effectively.) This is when you use the clutch to disengage the engine.

This is applicable, irrespective of which gear you are in or what speed you are traveling.

This does not cause any jerks or any discomfort to the passengers or any harm to the car.

Use both the clutch and brake simultaneously only if you are moving at the minimum speed of the particular gear you are in.

Engine Braking - is recommended only in case of brake failure.

In case of BRAKE FAILURE, you have to downshift a gear or 2 or more gears or more depending upon the situation to use the engine for braking and stopping the car.

This caused the rpm to move up, the car to jerk and slow down, and is not comfortable to the passengers.

Better uncomfortable passengers than injured passengers.

Thanks PC1984.

This has been the way I was instructed way back when I started driving, and this is the way I drive. Found no issues till now. And, (thank God), didn't have any brake failure too.

This is the same way I had learnt driving way back. I did not even know then that it has a fancy name like engine aided breaking [:)] But it works for me and has been working for last 13 years.

@Highway Ranger I think there has been lot of confusion here. thread title say something else and we discussing something else. we are discussing how use clutch properly and now suddenly brake came between.

btw I drive same way you do and completely agree with you . but too lazy when I am in traffic and coming down from flyover I simply put it neutral :-P

I completely agree with your first statement. I personally press clutch completely to engage gears whether down shift or up shift.

As far as engine assisted braking is concerned, highway ranger elaborated it beautifully.

But your last point is very dangerous and I would request please do not put the car in neutral while coming from a slope be it flyover or hilly area. Chances of brake failures or effectiveness of braking would be jeopardized during that time (it is a request). [:)]

Well happy to answer your query- The more time you keep you car at Idle, the FE will drastically go down.[confused]
Running in neutral is not called idling,and this should be avoided too.(will come back to it)
Idling means your car is stationery and engine is running.
The details-
HERE'S THE RULE OF THUMB: If you're in a drive-through restaurant, long ques at fuel station, Traffic signal with timer,or waiting for someone and you'll be idling and sitting for 10 seconds or longer... turn off your car's engine. Why??
For every two minutes a car is idling, it uses about the same amount of fuel it takes to go about 1.5 km. Research indicates that the average person idles their car five to 10 minutes a day.


.........
Very Informative post. I dint know many things which I now know :). Thanks for sharing.

Aah yes thanks for clearing the confusion! I follow the engine aided braking too. Whenever i see some traffic ahead of me i start to apply the brakes slowly and when the car reaches the minimum speed in that gear i put the engine in neutral and keep applying the brakes gradually. Its not that i always use the clutch pedal while braking.

I had this doubt in me for quite long and till now i haven't got it correct .

I have a habit of applying clutch before aplying brake ( i dont ride on clutch).

Is this correct way of doing ? Curious to know how everyone does it.
Exclude the case of panic braking !!

A few questions related to this,

(1) If brake is applied before clutch, will the backpressure in the drivetrain affect the clutchwear ? I feel this in my Alto.

(2) Does cars come with auto clutch while braking ?

Being a novice in this field, please enlighten me.

I thought that this thread was started about using clutch and brakes. Sorry, if I have gone OT.

The general rule of the thumb for climbing uphill and going down hill, is to climb down in the same gear that you use to climb up.

Never drive your car downhill in neutral. even if you are lazy it is easier to just ease off the accelerator than shifting to neutral. [:)]

I guess no one has gone OT, Discussion is outcome of queries related to one or the other and it is limited to driving style only.
We should change the thread name to, How do you drive? Proper Use of Clutch and Brake while driving
Mods: If you think it is correct please change the Thread name.

@ Drivetech4 LOL bro you are more experienced in driving than me for sure , I don't drive in neutral while going downhill. Still somehow i don't feel comfortable to change my driving style and use engine braking more often , i am comfortable driving like this. But let's see , i will try this method once and check.
Hi Dhaya,By the experience I mean to say-it is not the how many years of driving- Its the number of cars and number of kilometers you drove and in different driving conditions.
i am driving cars for only around 3 years now. But i trust my driving and have confidence in it.
And yes that's what I mean to say the Confidence and Trust about your own driving style.

The reason he said was that he was testing the focusing distance of the head lights under load. God knows what they do when we leave the vehicle for service.
That's why I never leave my vehicle with these jerks anytime. I rather prefer to ruin one day for getting my car serviced!!

Even i used to leave the car for servicing but it was just by luck that I saw one of these guys sitting inside my car with A/C on and ICE put on high volume with all door glasses up. this was happening when I went to take the delivery of vehicle after service and actually went 1 hour earlier.

Man the guy was doomed [evil]

.. but i have observed MASS guys starting off in2nd gear. is this safe for the engine.. most of the time the engine stalls. .. so i think i should write a letter to MUL. or is it safe to start off in 2nd gear? please comment..
I always start moving in 2nd gear now (may be because Manza is pulling well). Also started moving in 3rd gear sometimes.
Am I straining the engine/clutch too much?

Another practice is negotiating big humps in 3rd gear and applying clutch to maintain the rpm. Many times while doing this I have noticed that the car is not pulling enough and then found out that I forgot to down from 4th to 3rd gear.

You should avoid that, what is the purpose of first gear then? It is giving the unnecessary load to the engine and clutch.

You will require to replace the clutch assembly soon.Damage to engine to some extent as well.

if have read my post carefully then I have mentioned in traffic not down hill. I don't know what type engine brake I will use at speed of 2-5
