Rear Drum Backing Plate - Sealing Compound?

[Cunning Plan]

Gents, reading the Bentley manual for my bus, it states to use a sealing compound in-between the backing plate and the hub.

What exactly is the sealing compound? Is it just a black silicone sealant?  

[Roadkill]

No, doubtful it's silicone.  



That said I dunno.

Is it to stop dirt getting in ?  Or stop fluid getting out ?

It's to stop dirt getting in.

It is where the backing plate for the rear brake drum connects / sits on the hub, highlighted by the green area below:



Any suggestions? I've had a look for 'sealing compound', but there is not a specific thing to use

Probably like a RTV sealant will do, then.

Yeah, that should be fine . . . . leave it to go semi-solid before mounting the parts or it'll all squish out.

Thanks chap, I'll get some ordered!

Just have to remember to give myself a semi before attaching it for some reason I'll not question you though...

Great!  Now I have to clean out the coffee I just spat all over my keyboard!
