I'm doing a brake upgrade on the Hilux. Standard front brakes are useless if you fit bigger wheels and tyres. Fronts were fried at 40,000kM, I put new slotted rotors on and they are gone again.

So i've bought some new Prado 120 series T3 slotted discs (328mm, 28mm thick. Originals 297mm, 23mm thick), calipers (4 piston) and backing plates. These are the same as what is fitted to the TRD Hiluxes, same rears, same master and booster. Straight bolt on.

I've just degreased and pressure washed the calipers and am about to put some kits through them but they are still all ugly looking. What can I use to clean the alloy up? Carby cleaner? They are bright and shiny under the bolt heads.
