If you want to try it find a gentle slope with a nice flat safe area at the bottom, switch the engine off and let it roll under gravity. When the vacuum is gone you will be surprised how much effort is needed to stop. You may want to keep one hand on the parking brake.

Typically you have two shots at it so if the engine was out of control you have to make them count - no point in softly pressing at 120mph you want full ABS braking for as long as the vacuum holds up.

That is another thing everybody should test at least once - an amazing number of people lift their foot if ABS triggers and lose braking efficiency as a result. If stopping quickly is essential you need to know how to do it. It was even more important in the days before ABS.

While the car is moving at speed heavy steering isn't a problem.

And force it down into lower gears. Drive with automatic change up as speed increases is more hairy. And part of the problem in this original report seems to be a flappy paddle semi-auto gearbox.

Thereby loading the crankshaft thrust bearings before there is any oil pressure - Yecch!

My experience of UK parking lots is of bays big enough for bicycles. something to do with the shortage of real estate, I guess.

I remember an occasion some years ago, driving my (then) BMW in stop-start traffic on packed snow, where there was enough torque with closed throttle to overcome the rear brakes and push the (locked) front wheels. Only solution was to select neutral every time the traffic stopped. Something to do with the fancy front/rear brake proportioning.

when you press the clutch you basically have the pressure plate force between the throw out bearing and the crankshaft thrust bearings

Yup.

Pressing the clutch pedal causes a thrust bearing to push on the clutch fingers,disengaging the clutch. The reaction pushes the *whole flywheel* forwards towards the crankcase. The load is taken by whatever thrust bearings the crankshaft has.

If the clutch is badly out of adjustment, and tries to "overthrow", ie. the release mechanism bottoms out before the pedal bottoms out, thrust loading is limited only by the strength of the driver. Used to be very common in the days of non-self-adjusting clutches, especially where they had been adjusted to engage at the top of pedal travel rather than per maker's instructions. Usually went undiscovered until the front seal let go, due to about 1/8 inch end float in crankshaft.

IMO, engines should be started with feet off everything.

Depends on the design... maybe you're right, on Europeon designs ;-) ...Jim Thompson

Even the brake? Europeons, sheesh!

I drove my '66 GTO through Daleville ALabama in reverse. It was bright red, being escorted by a white police cruiser, with flashing blue lights. A drunk stumbled out of a bar, did a triple take then turned and fell back into the bar. :)

Must have been an auto in drive, right ?. In drive and at standstill, the box will be in low ratio and the torque converter does the rest. A lot of cars in the past had a brake limiting valve in the hyd circuit to the rear wheels to prevent rear wheel lockup. Don't know if they are fitted now.

Have never owned an auto box car, not even a tiptronic, i'm happy to say :-)...

The BMW was more involved than that. Fly-by-wire computer controlled ABS. Separate pipes to each wheel.

I've had both, including a few with worn out synchronizers. I still instinctively double-clutch when driving a stick, well, downshifting anyway. Dunno which I prefer these days. Modern autos are pretty good.
