Brake Drum Swap in Pursuit of the Brake Pull

Brake Drum Swap in Pursuit of the Brake Pull


The Sport Coupe has been exhibiting the long standing brake a little more as time goes on. The left hand front drum has always had a few issues so it was time to swap it out with the one I acquired a while back.

As you can see the drum is quite marked up and has transferred the marking to the shoes.

The brakes shoes cleaned up well and the replacement drum was fitted. As you can see it differs slightly having the later grease cap. Everything fitted up OK. The white wall needs a good clean. Will run the car and see how the brakes perform. The previously fitted brake drum will go off to be resurfaced and will return at some point.

Brake Drum and Hub Clean Up, Further Identification


After having the inspection and repair carried out on the drum it was now time to clean up the drum and inspect the bearings.

After a soaking in the paraffin bucket to loosen up the old grease it was time for the parts washer. Parts washer is a little small but does the job

Bearing are being soaked in Paraffin and appear to be in good shape and Timken originals having the Ford markings and part numbers. Reason for soaking is again the need to remove the old grease.

Things are now a lot cleaner and the bearing races are in as good a shape as the actual bearings

Looking at the part number it seems this is a 1940 – 48 hub and drum so should match the one currently on the drivers side.

Currently and since I got the car the drum on the passenger side is the Lincoln type as far as I know, either way it doesn’t match

These differ as they are ribbed

You can see the state of things when the car arrived nearly 10 years ago here

Once the bearings have had a good soak then work can continue.

Need to do some research on the grease cap on the “new” drum as it’s threaded and my be difficult to obtain.

Brake Drum Investigation


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
