Painting inside brake drums
 

I am starting to paint my new cast iron brake drums. I would like to get an opinion on whether to paint the inside of the drum (non-brake shoe area only). I would think it would keep the drums from rusting, but would the paint cause any harmful effects?

I paint them on the inside, but make sure NO overspray gets on the brake shoe contact area. Even a light dusting of overspray makes them very grabby.

I believe its a good idea; have always painted mine over the years and have not experienced any problem. Just my opinion !!!!!!

Ditto to the others.

I also agree!!!!

I think it is a good idea.

I made strips of heavy paper (I think from an old calander) that I used to mask the inside of the drum. A little tape would hold them in place. I used Black hi-temp Brake Drum Paint thet I got from Eastwood. Immediately after painting, I would remove the strips and wipe the friction surface with lacquer Thinner to remove any residue.

I've always painted mine with rustoleum. Some have been painted for over 30,000 miles and still look great.

I've got a trick for painting the insides of the drum. Take a thin coat of grease and put it where you don't want the paint. The paint won't stick to the grease, and you can take some lacquer thinner to it when you're done. It also works on decals you don't want to paint.

Agree with everyone, I use PPG DP90 epoxy, mixed 1:1 just mix what you need, mask the areas you don't want painted, and apply with a cheap brush, it flashes pretty quick so you can apply 2 coats. I use DP epoxy (black) on the chassis, u can top coat with any product you like. Just wipe down the brake face area with prep-sol or other solvent to clean off any oils and contaminates.

I'd use the DP90LF and just leave it. No overcoat needed.

No need to mask if you paint the inside of the drum before it is machined.
