Is this safe for brake rotors and calipers

I'm not sure on that, but try a small spot, and see but I would asked your mechanic if it is, safe to use, Me personally I wouldn't

what is concentration of hydrophoric acid

http://www.loctiteproducts.com/p/s_trmt_naval/technical-data/Loctite-Naval-Jelly-Rust-Dissolver.htm This is a link to the MSDS for the product. The exact concentration of phosphoric acid is a trade secret, but it is between 10% and 30%.

Is this the pink gel or liquid?

It is a jelly, not a liquid. I don't remember if it is pink, but I think so.

I have an old plastic toy with a very rusted metal part. It is a tub with what looks like a metal bell inside. Would this product harm the plastic?

I would say since in comes in a plastic bottle, it is probably okay to assume it would be safe on plastics.
