Great video it gave me a clear picture of the breaks on my 63' Chevy Nova this is the best I've ever seen explained.Thanks for sharring love the vintage film God bless 🙏💜
The spring wrapped around the drum prevents brake squeal. Under some conditions the brake drum rings like a bell with a squealing noise, the spring damps out the vibrations. They had a similar problem on disc brakes, solved by putting a rubbery paste on the back of the brake pads.
Over-complicated design (and flawed, for example when drums are very hot, there's nothing to prevent excessive self-adjusting action, like bi-metal mechanism or something like that). But video is good (old instructionals were the best).
These vintage “war time” videos are THE BEST instructional videos! I love how concise and explanatory they are.
I always wander how the self adjusters work . now I know what I did wrong. thank you for the show.
Great info for restorations! Love the vintage recording 'skip' at 6:00
Absolutely the BEST video I’ve seen! It’s an old video but extremely informative!!
Albeit old, This is a very good and the best I've seen film for drum brakes. I've a 64 Impala and it's a perfect reference for it.
This is the best video I found on drum brakes.

I got totally confused from 6:02 to 6:09 But got back on track on 6:10. Great film.
Same system on my 68 c40. Great video
Same system is still being used. It was way ahead of its time as a mechanical engineering
Oh wow, thanks for sharing this. It lets me see what my '64 C10 brakes should look like.
I think they started self adjusting on C10 in 64. 63 did not.
Thanks for this video.
Great video!
GM trucks '90-2000 - same system. Гениально конечно.
If only youtubers these days knew how to film proper teaching films like this
Ah , signs were getting older....like older....lol
Lol good old days!
Has anyone done this upgrade to a 58 Chevrolet?
I noticed a long spring around the OD of the drum. Cooling spring? Weird.
Alex Powers My '55 Chevy had that on em when I first bought it too. Have no idea what it's for but maybe it is cooling as you said
They were supposed to be to prevent vibration. I'm not sure how effective it was. Most aftermarket drums wouldn't have them.
@@Sonos45 Correct, they are not an essential part of a rebuild.
@jason9022 no their not

A skip at 6:02 that was funny.
Or minus 1/16” inch
Good old asbestos days

How many times do you push the brake pedal backing up when the drums are hot?
