Rotor Protection

I am in the process of a Restoration and I spent big money on my cross drilled rotors and they are begining to rust already. I know this is not a problem if the car will be driven - the rust comes right off. My concern is the build may take two plus years.....

Is there anything I can put of brake rotors to stop them from rusting and causing deep pitting B4 I get a chance to run the car down the road? I know I can paint the rest of the rotor that doesn't touch the brake pad, but what about the stopping surface? I dont want to contaminate the pads w/ WD40 or some other penitrating oil?

As long as the brakes aren't going to be used, I don't see any problem w/cleaning them off w/some lacquer thinner and shooting them w/a light cover coat of lacquer paint from a rattle can.

Just keep the pads clean.

Pull the pads out of the calipers and put them in storage and put some lps 3 or grease or other protectant on the rotor wear surface. Wash it off before you do final assembly.

Cast iron doesn't usually rust so bad it pits, just from moisture in the air, but it does discolor.
Some companies sell rotors with a zinc wash (quick electroplate of zinc or zinc/nickel) to keep the rotors from rusting up before you use them. Then you just run them and the zinc wears off.

Later, mikey

won't the paint contaminate the pads once I put the car into use? or are you saying spray them for now and then remove the paint B4 I put the car on the road?

Yeah, just wipe the light cover coat of lacquer off w/lacquer thinner would be my suggestion, just don't leave it on when you go to drive it is all.

you could coat them with grease and before you use them remove the grease with degreaser then clean them with lacquer thinner to make sure all of the greas has been removed. If you do this make sure you remove all of the grease because the grease will caude the asbestes of the brake pads to deteriorate and fall apart

I would just pull the pads and spray the rotors with wd-40. It will keep the moisture away and will wash right off with bake cleaner or paint thinner when you are ready

The problem with pulling the pads is when someone inadvertently touches the brake pedal. A better solution is to simply remove and store the new rotors and put old ones on for now.

Yup that would work. The new ones will still need to be protected. I actually put a brake system together recently and didnt have the rotors yet. We did all the bleeding with a block of wood in the caliper. We left it there after bleeding just to head off what you are talking about.

This is what manufacturers use...good luck finding it in a rattle can, contact the manufacturer for a sample.
