Reply To: Anti chatter brake drum springs

[Gregory Long]

There are springs, rubber straps, and other anti-squeel devices used on a brake-lathe to prevent a drum from ‘singing’ while it is being cut. A brake lathe turns a drum a very slow speeds.

But the springs used on the drums, on the car are much heavier tension. This is necessary to prevent the spring from ‘growing’ from centrifugal force as the car travels at high speeds.

I’ve used a spring door return spring to stop a squealing drum, but they expand and fly off at about 40mph. I’d love to find a source for actual drum springs.

If you have them, I’d keep them and use them. Big drums are prone to ‘singing’ for various reasons.
