To give an extreme example; park your car on a flat road and leave the handbrake off, with the engine switched off. Select first gear, and then get out and try to push the car. You probably won't be able to make it move. Now select sixth gear and try to push it, and you will be able to move the car. This is because sixth gear is a longer gear than first, meaning that for each revolution of the engine, the wheels turn further than they do in first gear. So to stop your car rolling away, the most effective way is to select the gear with the shortest ratio (i.e. first gear). Since reverse gear is normally a longer gear than first gear (that is to say that your car will travel faster in reverse gear than it will travel in first gear), reverse is technically going to offer less resistance to your car rolling away.Migizi wrote: ↑Sun Mar 10, 2019 10:53 pmI do not understand, but I am interested in learning more - (despite what my wife says )wonkydonkey wrote: ↑Sun Mar 10, 2019 4:09 pm ..., reverse gear is typically a longer ratio than first gear, meaning that leaving the car in reverse will increase the chances of the car rolling away if the handbrake fails!

I thought it was first facing uphill or flat, and reverse facing downlhill ?

I'm happy now!
My problem ridden Steve has a perfect handbrake! ,
The back-end raising is normal, old folk will remember the likes of the aleggro which would raise 6"" in the air

If you ever think I'm off my rocker.. Just put me back in it and walk away... It's the kindest thing

Thanks everyone for your input.
It holds ok, just never had a car that does that before. I’ve come back to a couple of other cars before that had gently come to rest against somebody else’s bumper, but as my drive way is said slope, getting up in the morning to find it pressed up against my outward opening front door could be a little inconvenient!
