1) At 5:09 what do they use for de-rusting? Nothing from Home Depot works that well or fast.
2) At 7:05 what is the material they use to reline them with? Looks like cork strips.
3) There must be over a hundred different brake shoes. How do they know what they fit?
4) At 15:45 it looks more like a sawdust mixture. Hope there's no asbestos for his sake.
 
1) Muriatic acid?
2) It looks like brake lining material to me.
3) No clue
4) It looks like brake lining material to me, but I sure wouldn't want to breath it.
 
Fascinating to watch but I hope those crappy parts stay in whatever part of the world they filmed that in. I feel like this is how things were done in the U.S. 140 years ago.
 
I guess I wasn’t too impressed because back when I was a teenager, we had a mechanic in town who would reline brake shoes. He had his own machine and would rivet the friction material in place instead of bonding it. He had 8-10 different sizes of shoe material and the big advantage was that he could have the old material off and have the new material riveted on in about 5 minutes for four shoes. Yes, these were asbestos shoes. Yes, he also buffed on the friction material when he was done. With no mask. Anyone here remember when you had to return your old cores when you purchased remanufactured ones? You know those factories had clouds of asbestos floating around, as well as the back of the trucks that returned the cores.
BTW, the old local mechanic who worked on these asbestos shoes most of his life did not die from lung cancer.
 
At the end the nice box says asbestos free. I bet the ground is filled with it from the old shoes. Nothing like having the young work while they are still alive.
 
Asbestos is long banned in 1st world countries(and it landed braking and roofing/insulation companies in court) but Russia is the world’s main and only miner of it. Australia was also a major supplier until their government outlawed mining and distribution in the 2000s.

Looks like India or Pakistan/Afghanistan/Bangladesh - and those shoes will wind up on a Hyundai/Tata/Mahindra/Mitsu Fuso truck there.
 
I bought a set of rivet on linings from J.C. Whitney for my 1959 VW van. Also got the rivet tool for like $15 and that was about 50 years ago. Put them on all wheels. That thing had amazing brakes with it dual cylinder front brakes. They wore like iron and never needed to replace them.

Actually I remember visiting a place like that in Cleveland in the early 70s LOL. And they were finish grinding asbestos filled linings without any PPE.

I've been told that it's not much of a problem if you don't smoke. But a devasting negative synergy between the two irritants. There were many people who worked with asbestos building stuff for WW2 who were also heavy smokers and died in the 50s.

That bird starting at 6:37 is laughing its tail off
 
muriatic acid. when you’re done dunk it in something basic and then add protection

phosphoric acid is a toy
From what I remember from the hod carrier I asked about it, muriatic acid is a cheap type of hydrochloric acid. Brick layers use a diluted form to wash off the white scale that can form on new bricks.
 
still used in the US for friction parts
Not very common. All automotive brakes are required to be marked for asbestos/heavy metal content with the leaf mark.

Though, the chlor-alkali process uses asbestos membranes. Allowed by the EPA/Health Canada.
 
I've relined brake shoes for busses when I was a mechanic. Same size as trucks would have used, 22.5" wheels and all drum inside them.

But I only did it once, the busses with brake drums were phasing out in favour of disc brakes. We had the lining material, the rivets and a rivetting tool so I just made a couple sets. Do it wrong and you break the shoe linings though. Not sure if they ever got fitted....
