    How to Desalinate Seawater

    Zinc is highly toxic in fume form, for instance when welding galvanised iron or steel; or at temperatures above about 450 centigrade, which may be attained by coke or charcoal burning in galvanised containers.

    Didn't the loaded wheel move then? I was sure that's what caused mine to fall off the jack, but it was a few years ago now, about 1971 when I had the oldest Beetle, a 1958/9 model. Also seemed to keep both wheels turning in snow, sand, mud, etc.Either way, as I said with the Daf, you couldn't apply this method of starting, which was the point.

    Which is why I said more recent ones, and mentioned other manufacturers when referring to electric brakes. And gave examples of other cars from other manufacturers with parking brakes on the front wheels, some at the hub, some inboard, as you asked. My little AX has conventional rear handbrake, and no modern features at all. No central locking, no EMU, just a normally aspirated, mechanical injectors, diesel. It only has single wipers front and back. (Doesn't have the hydraulic suspension either, but I quite liked that on the BXs I've had.) The only reason I don't use it so often now is our age and increasing girth is making getting in and out a bit more difficult. I keep it for a spare, because it's so cheap to run ( 65 miles per imperial gallon, 4.4 litres per 100kms) and easy to m...

It's worth less than a set of tyres for the C4 anyway.

    My C4 Grand Picasso has an electrically deactivated parking brake, look on any citroen owners site and judge from the number of questions and problems how stupid an idea they are.Extract from C4 advertising: "Automatic electric parking brake (standard)The automatic electric, parking brake, which is fitted as standard with all gearbox versions, improves both comfort and safety. The brake is automatically applied when the engine stops. An ECU works with the ESP to calculate the force required to immobilise the vehicle depending on the gradient of the road. The system includes a continuous monitoring function to readjust the brakeforce when, for example, the vehicle is loaded on a slope or the temperature changes significantly. The parking brake is automatically released as soon as t...

The parking brake is automatically released as soon as the torque applied to the drive wheels is sufficient to move the vehicle forwards."If the engine won't start the brake has to be released manually, I'll leave you to look that procedure up yourself.I don't think it was citroen who started this on cars, BMW and Audi had a version before Citroen I think. It's now becoming quite common.I suppose it's only a step on from the brake coming on when you put an automatic in Park.I prefer the manually operated parking break, just as I prefer the manual gearbox, in my little Citroen AX. Alfa sud had front wheel handbrake, SAAB have used it ,and again some citroens on the drive shafts. Our old SEAT, that looked like a Peugeot 404 or Austin Cambridge, had handbrake on the prop shaft.Any variation on a design has probably been tried somewhere.

    Quick perusal of om spec should have revealed one belt to each wheel, which with the CVT system has same effect as lsd, so the wheel with least resistance does spin most, but the load bearing wheel still moves. That's why the little 44 was so good in snow and mud, it kept going. The 2 engine end pulleys are linked to the engine by a prop shaft. The point was you wouldn't start one with this method.As for the old beetle, the loaded wheel did continue to creep, this was my experience from the time, apparently confirmed 50 years later. If it wasn't a full lsd it did a good imitation.https://www.youtube.com/watch?v=V4q_6YjPQ3k

    I'm pretty sure my 1957 model beetle did, along with the other transaxle ones.Also had a DAF 44 belt drive auto with lsd.
