Any - Holding the car on the clutch on gradients - craig-pd130

Just a passing observation about the number of drivers that prefer to hold their cars on gradients using the clutch rather than the handbrake.

My commute to work takes in a short hill (about 1in 8) which has a set of traffic lights halfway up. Every morning there are several drivers holding the car on the gradient using the clutch.

They are not driving autoboxes as they don't have brake lights on, and the cars often roll backward a little before trickling forward again -- which they wouldn't do if they were autoboxes in 'Drive'.

Seeing this got me thinking about DMFs and failure rates. While I'm sure that these complex components DO fail prematurely, abusing them by holding cars on the clutch on a hill isn't going to help at all.

Isn't this what the handbrake is for?

How you drive a car will be the deciding factor as to how long it will last before a major breakdown clutches and autoboxes especially ,how man people using auto boxes use the foot brake and keep the car in drive at junctions instead of using the handbrake and neutral.People complain about DMF failures and yet in lot of cases its there own fault there are taxis doing 500000 km on the original clutch so they can last if treated properly.Many of these cars are not owned by the driver and they do not care two hoots.

Bad habits holding the clutch in when there is no need .Same for a automatic car whilst stopped lever in neutral handbrake on.The majority of people are not mechanically sympathetic and treat a car as a piece of junk which cost a lot of money when they go wrong.Same as waiting till things go wrong instead of replacing parts.We had the same at our workplace preventif maintenaince was stopped due to cost cutting.We had a few pump fires due to this and if it wasn't for us as voluntary firemen on the site attending to this could have had a serious outcome.

In a similar vein the number of people who sit at the lights at night with foot on the brake blinding the driver behind with their high level brake lights.

Just bad driving, and no thought for anybody else.

Spot on Vitesse,why keeping your foot on the brakes whilst stopped.All I think of they must be frightened somebody running into the back of their car.Strange behaviour or maybe they don't know they have got a handbrake.

What 's a handbrake?

(or indicators?)

Hmmmmmm,

I occasionally do this to amuse myself, driving a diesel as I do mostly, at flat tickover reves, and since I got 230,000 on the clutch I do not precieve there to be a problem.

Is there?

Cheers

Never mind wot can one say.

The take up of drivetrain slack with the accompanying thump every time you put your auto in drive probably causes more wear and tear on the 'box and drivetrain than leaving it in drive at the lights.

Not if the box has been designed for Americans. It has to be ****proofed first....

@ dieseldogg -- trickling / rolling forward at idle rpm, in first gear, with foot off the clutch pedal is different, I'm talking about holding the car on an upslope by slipping the clutch for minutes at a time.

Thats what I was thinking craig what you wrote.

Merry Christmas.

Any - Holding the car on the clutch on gradients - dieseldogg

Nope I understand what you posted, I too was talking about holding on a slope, else how could i run back?

There is one roundabout in particular in town where this is almost obligatory ,with quite a long up-slope approaching it, using the handbrake is a complete pain in these circumstances.

Where I grew up there was a moderately steep brae right outside out gates, the wee bedford van (pre MOt in NI) had NO handbrake, preforce one larned fast.

None of the cars owned by our family from new to complete scrap EVER needed a clutch.

just a thought

Dieseldogg, fair enough. Maybe I'm clutching at straws :)

Sorry I should point out that I/we have not had any experience of DMF's (yet)

our last motor was/is a 1998 the replacment is a 2010 DSG boxed Octavia.

However from observation of the driving habits within our local community both from the passenger seat & also the footway......... clutch misuse & abuse is endemic.

Plus observation within my workplace on tractors and in vans.

Mostly "riding" the clutch that is keeping ons foot on the clutch between changes or indeed all the time.......... more common than might be imagined and on the few occassions I have commented ( being responsible for the vehicles) the offender denies it so they realize it is wrong but they still do it.

The other "crime" is excessive revs due to the apparent inability to match clutch load to engine output that or the lack of the necessary fine motor skill needed to so modulate a clutch.

cheers

I have a car with an electronic handbrake, I personally cannot see the point of replacing tried & tested lever & cable handbrake technology with expensive electronic sysyems apart from the electronic parking brake makes it impossible to roll back on a hill start for those drivers incapable of controlling a car.

There are times when the parking brake needs to be applied for a split second for example when the traffic lights are changing just ar you are reaching them and there are 1 or 2 cars in front, applying the electronic brake is too long winded.

In the good old days, everybody said that clutches are more expensive to replace than brake linings. Well, in my car with an electronic parking brake, the read brake pads had to be replaced at 33k miles (10 months old) and an electronic parking brake actuator failed at 68k miles and was a £1,000 repair (£675 for the actuator, 2.1/2 hours to fit plus VAT). I guess replacing a clutch will cost less than £1,000 so is holding the car on the clutch now a cheaper option?

Subaru have 'hill-holder' clutches on many of their cars.

Mechanically it is little more than a ball in a tube that rolls back on an incline - if the brake is pressed while the clutch is depressed, one lifting one's foot from the brake (eg. to press the accelerator), the pressure is maintained in the brakelines preventing rollback.

Once the clutch rises to biting point the pressure is released and off you go - no stalling, no roll-back, no electrickery to go wrong.

Simples.

(And a normal lever for when a handbrake is required).

I have had one clutch failure in 40 plus years of driving. the car broke its clucth driven plate when I attempted to drive out of my garage. I was the second driver with 36k miles.

It was a Rover 800 which explains everything.

People hold cars using the clutch. People buy Renaults..

There are always people who have no sense/don't care/are pig ignorant. There always will be..

Buying Renaults with electronic handbrakes is testing your luck a bit far tho :-)

Wor Skoda got a proper handbrake ...........pity though about all those electronic gizmos associated wit der DSG

An automatic car has usually the following settings shown near the selector, park, reverse, neutral, drive and perhaps D low or something similar. Now for all of those who advocate leaving it in drive whilst stationary ask yourself one question, just when would you select neutral then ? Not when driving and not when parking so it is not exactley rocket science to conclude that neutral can only be for use when stationary if more than a few seconds ! Simples !!

Not only. I often coast in neutral - down long hills, approaching roundabouts, slip roads off dual carriageways and traffic lights [one click on handbrake just before stopping so not dazzle anyone behind].

That's how I get more than 30mpg from my 2.8V6 petrol engine. [admittedly a beautiful piece of engineering with 5 valves per cylinder for good gas flow]

Complex!!

Modern engines use more fuel in neutral (idling) than with closed throttles (nil used) although there will obviously be more engine braking in gear.

Modern engines use more fuel in neutral (idling) than with closed throttles (nil used) although there will obviously be more engine braking in gear.

I know. But I have argued in another thread [coasting] that more energy is needed to keep the engine rotating at above idling speed than just at idling speed. Assuming your journey starts and finishes at the same level, all this energy is produced by burning fuel.

And holding the car on the clutch is doubly foolish because not only does it wear out the release bearing and plate, it uses extra energy because the clutch plate has to heat up because of friction.
