Only one EV charger at home?!

I'm curious. The "About" for the group, sci.electronics.design, says "Electronic circuit design".

But, it seems like hardly any of the content is actually about any of that, not science, not electronics, really not design except in a complaining sort of way about societal fungshwei.

That's okay, it is probably as much fun as electronics for some. But, maybe we should change the "About" text?

Totally?

That's not supposed to happen. You should only lose the assist, so you just had to press the pedal harder. Depending, you'd feel the brake become "hard".

I remember that I would play with it. Car parked, engine stopped, press the brake pedal and release. After two or three pushes, it suddenly became stiff and would not yield: the vacuum storage was spent.

I don't know how the assist works in my current car (an Opel Corsa). There is no vacuum storage in sight.

I meant "here, the car is provided by the driving school"

...

I don't see any "about".

But conversation often drift. The initial question was related somewhat to electronics, then it drifted.

Yes, there are some threads about electronic design. And some about politics.

I don't know what that refers to. I don't recall removing anything.

We have never done it like that, just use normal unmodified cars, both when learning in your own car and when using the car provided by the driving school..

Yeah, I realised that's what you meant, but here, most do the test in their own car. Only those who don't have a car use the driving school car, and the driving school cars are unmodified cars, no extra pedals at all.

My father had a couple of Citroens, with their hydraulically assisted brakes. There was an accumulator to allow the brakes to stop the car if the engine failed, but after a couple of presses, there was NO noticeable braking at all. When I had to tow him, we used a rigid bar, as he effectively had no brakes and I needed to brake for both cars. Luckily we were only going a mile and a half to a garage.

In my case, the brakes did work, but you had to press really hard.

You did it again.

You have to post, at the same time, to three groups in a single post. If you don't, there are people that will not see your post.

alt.home.repair, uk.d-i-y, sci.electronics.design

AFAIK, that is forbidden here.

If he's posting through Google Groups, they don't give him any choice. He can only post to the newsgroup where he's reading.

it is the same for vacuum assist

That's normal for most cars, using vacuum servos to assist the existing brake master cylinder. Citroens are different (they seem to like to be weird), using a hydraulic pump to power the brakes (it also powers the power steering and the rising and falling suspension), with a small accumulator. Once that accumulator is emptied, not only is there no assistance, but there are no brakes at all.

But not some Citroens, where everything is hydraulically driven and not just assisted. A few presses and the brakes give up completely.

Yes, when running low on petrol, I once coasted for a number of miles coming down from the Pennines. The car did not have power steering, so that did not get harder, but the brakes took a lot of effort.

In the UK, manual driving school cars usually have a brake and clutch on the passenger side and the instructor is trained in methods to grab the wheel, while knocking the pupil's hand away from the wheel (two different moves, depending upon which way the instructor needs to steer).

Anyone with a licence that they have had for at least 3 years and being over 21, can instruct a learner in a normal, unmodified car. The learner can take the test in an unmodified car, but most use their instructor's driving school car.

Many cars use the Bosch iBooster which is comprised of an electric hydraulic pump with an accumulator.

It is common on electric cars as they don't have a free source of vacuum.

kw

Yes.

My instructor died doing that. He saved the life of the student, pulling the steering wheel and avoiding crashing against an incoming car, but crashed into a lamppost instead (at the pavement on the right side of the street). He entered the hospital on his own foot, but died hours later of internal injuries. Ruptured liver, I think.

He did not appear at the agreed place to collect me for the class. I went back home, somewhat fuming, then phoned the driving school asking why he did not appear. He is dead, they said.

Blaam! Bummer.

The have a sensor on the pedals. If the instructor has to use the pedals during the exam, a beeper sounds and the student is failed immediately.

Ow :-(

I've been in that situation a couple of times before dual systems became standard. Even with a dual system after a porcupine chewed through a brake hose going to the front caliper I found the rear brakes on a F150 don't do much in the way of stopping.
