The Model A has an early Ford juice brake setup rather than Henry’s original mechanical system. The car is exhibiting a bit of a brake pull under heavy braking and left front brake drum is a little scored.
I was given a drum a while back that is marked “cracked” so decided to investigate condition.
The drum has been stored in the shed for quite a while, so being cast it’s a bit rusty
Had a go at cleaning up and removing the majority of the rust
What seems to be the original wheel bearings seem to be still in place and in good shape.
Part numbers appear to be visible on the drum
Next step will be to run the drum up on a lathe to further clean the braking surface and check for cracks. But so far so good
Most automotive machine shops have a brushable dye that will show up a crack in cast iron, or they can use iron filings and a magnet to show a crack. Not every crack is visible to the naked eye, even when the drum’s friction area has been cleaned up.
Thanks Bill, yes indeed that’s where it’s going next. My friend has a company that can help https://ozcraft.co.uk/
