Hydraulic clutch

    Hi there

    I am learning to drive at the moment and all is going well. Of the 2 cars we have here at home my mams and dads, my my mams car is the easier to drive for me. When I take my foot off the clutch the car moves without me stepping on the accelerator.

    However with my dads car I must wait for the bite and obviously this is more difficult (for a beginner anyway).
    I believe this is something to do with a hydraulic clutch that allows start off to be easier???

    I am thinking of buying a car myself after I have passed my test, are there certain makes of car that have hydraulic clutches? or is it hit and miss in that respect?

    any advice would be greatly appreciated

    It's not to do with the clutch, is there any chance that your mams car is a diesel and your dads car is a petrol???

    Didn't some cars have a cable operated clutch?

    Learn to use the clutch properly (just a matter of getting used to) and then you can buy whatever you want, regardless of clutch.

    Starting off with the clutch fully released and the engine just idling isn't ideal either btw ...it might be easier for you right now, it certainly isn't easy on the engine, as you are labouring it

    The clutch just transmits whatever torque is available from the engine flywheel up to the gearbox, whether it does this mechanically by way of a cable or hydraulically by way of a concentric slave cylinder or an old fashioned clutch cylinder and clutch fork arrangement, does not change the torque that is available at the engine flywheel when the engine is at idle.

    Diesels have more engine torque available at lower engine speeds, than petrol engines have, which is why you can yet your foot off the clutch and the vehicle will move off without using the accelerator on a diesel car, whereas on a petrol car, without using the accelerator, the engine will stall, because the torque available from a petrol engine at idle is not sufficient to move the car from stationary.

    I'd say the fast-idle setting on your Mams car is possibly set too high....its not normal to be able to pull away with no throttle. Hydraulic clutch has nothing to do with it... imho

    Usually yes.
    I parked my petrol car in-gear (dont usually do this, but on a little hilll) with the handbrake on and turned the wheels into the kerb "just in case". Came out and like a tool forgot I put it in gear, started it, "hopped" it as it was ingear but it didnt cut out, far from it, it actually drove itself up the kerb (with the handbrake on) onto the path and would have continued had I not held the brakes down. Never cut out though.

    Ive noticed before that it will almost drive like an Auto if you put it in gear and let the clutch out. I dunno if/when it would cut out. Maybe something wrong with it, but no doubt a very easy car for a learner to drive (5.6l V12 BMW).

    Yeah, 6speed, 380bhp, 850CSI. People dont want to see me hijacking another thread though!
    Can read all about it here (on Irish plates now though). :)

    Sounds to me like you should get the hand brake checked out.

    At 380bhp and the amount of torque that V12 would be putting out, bolting it to the ground wouldn't hold that thing in place..

    At idle, wheel against the kerb?

    Excellent -love those stories - btdt, good to see others doing it too.
    One thing I notice in that thread, and which I've direct experience of myself, is that UK MOT thing. It's definately á la carte.......my 968 as bought had one, but there's no way it'd have passed an NCT - I reckon there's a lot more dodgy MOT's out there than you think................maybe worth a thread of it's own......mmm

    Ode To The Motorist

    “And my existence, while grotesque and incomprehensible to you, generates funds to the exchequer. You don't want to acknowledge that as truth because, deep down in places you don't talk about at the Green Party, you want me on that road, you need me on that road. We use words like freedom, enjoyment, sport and community. We use these words as the backbone of a life spent instilling those values in our families and loved ones. You use them as a punch line. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the tax revenue and the very freedom to spend it that I provide, and then questions the manner in which I provide it. I would rather you just said "thank you" and went on your way. Otherwise I suggest you pick up a bus pass and get the ********* ********* off the road”
