Like the title of the thread says. After several New England winters my calipers are accumulating rust. Any suggestions for removal?

 

steel brush...

Thats what I normally use before painting calipers. I plan to paint mine black this spring anyhow, just so the rust doesn't show.

 

how many layers of paint do you put on?

 

steel brush will do the job... I painted my brakes with hammerite, see www.hammerite.com ... I don't know if it's available in america. It's designed for painting over rust, it's not specially made for brakes but it's a lot cheaper and works much better in my opinion...and lots of colors
All corrosion stays away and it's been looking good for 3 years now. I applied 2 layers. Don't worry about heating... it will hold.

 

Hammerite is probably similar to Tremclad rust paint here in north america. Good stuff, although I'd prefer the caliper paint OR high-temp BBQ / Valve Cover paint on brakes, just in case the heat does affect it.

I spray one or two light coats, followed by two medium coats (never enough to leave a drip), and it's normally enough.
