Ribbed brake drums

Tend to agree Ret, Dr Terry.
Fraze,
General consensus is EJ EH drums can be slipped on to stock FB EK brake setup. The parallel radial ribs were stock on FE FC and most FB.

Well it looks like I can use the EH drums with standard steel wheels on my FB ute but before I buy them, I will try an old eh drum which a friend is loaning me just to be sure. Thanks for all the replies, cheers, Fraze

That's the best idea. Look forward to hearing the outcome.

Fraze, they do fit, I did a test fit on the weekend. I have an old rusty FB van and a EJ front end that I am fitting to my FC, I took the drums of the EJ and fitted them onto the FB front end and bolted the rims back on with no problems.

I just fitted a set of new repro EH brake drums to an FB, no issues at all,  . And in studying the whole situation I can't see any reason why you would not be able to use EH brake drums on an FE FC either. The only thing would be that the narrower FE FC brake linings wouldn't wipe the whole surface of the EH drum, but I cannot see that that would matter! Cheers, Fraze

Fraze, they don't fit because of the extra width in the drum, when you bolt them onto the hub they bind on the backing plate.

Possibly the EH drums could be machined down for clearance?

Yes, that's the solution proposed by another club member. In fact he's done exactly that to an FC he previously owned - bought EH repro drums and had 6mm taken off the drum edge. They fitted and worked perfectly. I passed this suggestion onto the original requestor that prompted the other thread (FE/FC Drums), and am waiting to hear the result.

Interesting comments about machining the extra width off the EH drums. Although I haven't actually tried EH drums on an FC yet so I might be going off half cocked BUT....... The extra width of the EH drums is on the mounting flange side of the drum and therefore is inside the well of the wheel!!! When I put the drums together on the bench and measure from the mounting flange to the outside rim of the drum the FC, FB and EH drums all measure the same (within a mm ) Certainly not 6mm!!! Over the next couple of days I will try an EH drum on my FC, Fraze

I think the difference will be in the FC backing plate Fraze.
