hi guys
Fitted brand new drums to my Freelander a couple months ago. I degreased them, wiped over with cellulose thinners, heated with a heat gun and then painted with black brake caliper paint-let dry and then baked on with heat gun.
The finish was amazing, however now I have lots of rust coming through :0(

what do you suggest...apart from Hammerite!!
 
There is a difference between the temperature of a brake caliper (the thing that pushes the pads together onto the disc) and the brake drum, (the bit the shoes are forced against to slow down). Use high temperature paint and it shouldn't burn off.
 
thanks for the replies, it said high temp on the tin hence the suggestion it wouldn't harden until it baked on so that's why I used a heat gun before bolting wheels back on..

it hasn't flaked or pulled off the drum-the rust is coming through it!

It does come smooth and shiny, or smooth and matt, as well as the hammered finish.

My drums are brush painted every year with the matt stuff and they look great - they dry with no brush marks at all.

I have the spray shiny stuff and do the wheel nuts every springtime as the salt goes for them.
Flat bit of wood and some dowel rod and the nuts are easy to spray and look like new.
 
I have used black smoothrite on the drums of both Freelanders and its worked well, the TD4 was done summer 2010 and is still looking good now :)
 
I have tried many different finishes on my rear drums but they always go rusty in the end. This summer I grit blasted the drums and painted then inside and out with VHT paint. Rust has just started to come through again. I have used Hammerite on the drums but it burns off around the circumference of the drums and then goes rusty. I think cadmium plating might be the answer if you don't mind the bling! or painting them annually.

I'll try Hammerite after I've scotch brighted the surface rust/dust off.
I used an electric hot air gun that we use in industry to collapse hooge heat shrink...just thought it would help a bit :)
 
p.s the paint I used was suitable for engine blocks too-I'd be well ****ed that I painted my engine only to have rust come through after a while!

Stearing clear of Halfords paint for a while now
