Brake Parts cleaner is made to be sprayed on brake parts...a job that requires it to have VERY particular properties. It has to evaporate with NO residue, and not soak into a brake pad. This makes it perfect for anything under the hood or under the car that needs a quick cleaning. I use it when cleaning out a tranny pan too. It's also safe if you happen to get it on an electrical connection, etc. Evaporates pretty fast, leaves no residue, and it's non-flammable.
You can get it on just about anything and you'll be fine. I did not recommend (and don't do it myself) spraying it on the outside painted surface of your car, but spraying it on the plastic and metal of every car I've ever owned, I haven't had a problem and the engine bays look great. Each to their own, however.
