The London Underground carried untold quantities of asbestos brake dust around the tunnels (and stations) for decades. Tunnel maintenance staff were employed to brush/blow/dislodge/collect it for years: what an unspeakable job. No-one should have been expected to do this.

And how many of them are left alive I wonder ? Do modern Diesel-Electric locomotives use regenerative braking or do they still rely entirely on friction brakes ? They certainly have friction brakes, but I wonder if those are mainly for emergencies and holding the train stationary at the platform and not used for slowing down.

Re: Dump Your Deezel
The brake dust on the Lada is horrific as well. It's not a particularly heavy car (by modern standards!) at 1021kg (995 for the saloon), and I make pretty extensive use of engine braking so I imagine that your average VW Passat or similar these days with double the horse power and no engine braking whatsoever is shedding twice as much.
No idea how much it is in the real world or how damaging the particles actually are...just given how big an issue that particulate matter is these days, especially in cities it made me wonder.
Also, never buy a car with white wheels...

Re: Dump Your Deezel
Looks like modern pad residue is carbon and iron, which would explain the black and the red.

SFAIR, there are alternatives, but many a lot more expensive, and not always well suited to normal public road use.

Re: Dump Your Deezel
Nothing particularly harmful there then Chris... Breath too much of it and you'll end up rusty but at least you'll never suffer from an iron deficiency!!!
If I'm not mistaken roughly the same stuff as in laser printer toner...
It does indeed explain why it's so staining and hard to removed from wheels. The heat will fuse the carbon onto them just as a laser printer fuser does for the toner onto the paper...

Looking at all the brake dust comments I think you're all too heavy on the brakes............. boy racers all of you.

Re: Dump Your Deezel
Distinctive smells are vividly remembered, and for a time travelling on an intercity 125 HST you would always get that smell like someone had chucked a load of hot iron-filings into the air conditioning/ventilation system.
Well turns out they had, almost literally by having the intakes in close proximity to the brakes.

Re: Dump Your Deezel
You should see how much brake dust I generate on my bike... I go through brake pads frequently!
Yes!!! And even now when a Virgin Pendolino brakes and runs into CMK station from 125mph you can really smell the stench from the brakes when standing on the platform...NewcastleFalcon wrote: ↑21 Jun 2017, 12:03 Distinctive smells are vividly remembered, and for a time travelling on an intercity 125 HST you would always get that smell like someone had chucked a load of hot iron-filings into the air conditioning/ventilation system.

Re: Dump Your Deezel
Clutch linings now smelly things too. Once an asbestos-brass compound, now a synthetic resin laced with glass-fibre-string, judging by the remains of a couple I've had chewed up by failing DMFs.
With the trend towards higher reverse gear ratios over the last 15+ years, a "reverse hill start" is now major (and often smelly) strain for the clutch lining on anything other than a lightweight vehicle, and made all the more difficult by a DMF which 'winds up' and then lets go.

Re: Dump Your Deezel
There must be something different about what modern diesels chuck out...
Just came across an old Dennis Dart based Plaxton Pointer bus (can't be many of them still in service surely) on a J plate earlier today, and got blasted by the exhaust as it pulled away. Okay, I was left in a cloud of smoke for a few seconds, but once I out of the cloud, that was it. No horrible taste in my mouth, no coughing and sneezing for ten minutes afterwards...though on the flip side, I'm sure they are far better for the environment these days than they were...
They still stink more than they used to in my opinion!

Re: Dump Your Deezel
I toyed with getting an ex-LT/Cornish school (or was it a community centre?) Dart a couple of years ago partly because it was, I thought, extaordinarily cheap, but also because there were so many in service everywhere that finding somewhere to fix/service it, wherever I happened to be, wouldn't be difficult.

Re: Dump Your Deezel
They're about as sophisticated as a brick...sadly they also weren't the best screwed together of buses. That said...nowhere near as bad as the ADL Enviro 200 which replaced the Dart...
Never seen one with slack in the rear axle that couldn't be measured in millimetres (hence a truly horrific howl and vibration anywhere north of 40mph), which didn't leak like a sieve or which was fitted with any form of useful heating or ventilation. Well...unless you counted the hole in the floor around the steering column which blew ice cold air up your right trouser leg anyway.
They did change hands for ludicrously low prices though, and I'm sure that it wouldn't take much fettling in the grand scheme of things to have a good show vehicle or a good little base for a motor home conversion. Still not a patch on something like a Volvo B10M based Alexander PS...though that's a much heavier beast - similarly cheap to buy though - especially just now with a lot of perfectly good old vehicles being scrapped due to the recently changed DDA regs meaning they can't be used on stage work any more.
For all the Dart had its flaws - was still *massively* better than Volvo's answer to that market segment. Usually clad in an identical Plaxton Pointer body to fool you, I think it was the B6L I think it was? Easiest external feature to spot was the odd flattened exhaust tip which protruded from the rear panel a good six inches from the bottom edge. In the interests of making a vehicle with a largely flat floor they managed to wind up with one that was drastically under powered and even more under cooled. They also positioned one of the main ECUs in the leakiest corners of the cabin with predictable results. Sure I came across one of them wearing an ALX-300 body as well...just as terrible, though that one did at least get me to my destination...which First's pair could never claim to have despite having caught them probably a dozen times!

Re: Dump Your Deezel
If you bus enthusiasts fancy buying one we have a company a couple of miles from here that sells them, there's a large yard full of them. Don't go looking uninvited though there's a couple of huge dogs on site.

Re: Dump Your Deezel
On an allied topic, I often wondered what happens to old time-expired commercial vehicles... You rarely, if ever, see an HGV tractor over a couple of years old now so what happens to them after that time?
Do they get shipped off to the third world for further use, are they recycled back into new lorries by the makers or are they just left to rot in a big yard like those buses?

They get sold off mostly to the African continent through specialist auctions/brokers Jim until they have such huge mileage on them that they are no longer useable, then they get scrapped and shipped to China as scrap metal for a pound a ton.
