Way's to Clean Up Rusty old Caliper Brackets?

Any advice on freshening up rusty old caliper brackets? I need to replace my rear calipers and don't want to mount up the clean new units to nasty looking brackets.

Thanks for your insight!

How much rust? Surface rust or super, pitted rusty? Steel wool or wire brush. Then you can paint them any color you like with caliper paint.

I wirebrushed, sandblasted, and soaked mine in Ospho for a day. Then I painted them with BBQ grill paint and baked them (in a bbq grill) to set the paint.

You could also try leaving them in vinegar for a week or two. Or maybe if you have less time, electrolytic rust removal works well but can be a pain to set up.

I sandblasted, then painted with high-heat paint.

sandblasting is the best if you have access to such equipment. Otherwise, whack the piece with a hammer. Preferably a pointy one. The layers of rust will crack off and it won't look so crusty anymore.

I've had pretty good success using a wire wheel attached to a drill. It makes quick work of the rust. Afterwards, I wipe it down with a bit of solvent or brake cleaner then a few coats of grill paint.

I brass brush and some WD40 tends to work wonders on a lot of rusty surfaces.

I freshened up an early 70's road bike (bicycle) that way.

bakingsoda blaster?

Electrolytic rust removal works pretty good if you've got time and no sandblaster... All you need is a bucket, water, 'washing soda', and a battery charger.

I'll also vouch for the electrolytic derusting process. It hasn't failed me yet. Kills rust, but leaves behind clean metal.

A vinegar soak.

would electrol... work on a slightly rusty, yet thick brake rotor?

Edit. i read the entire thing and i dont think it would be a good idea
