For cars it's terrible but for a cleaner,,, Hmmm maybe?

I doubt you can by chlorinated brake cleaner anywhere. It's removed from sale in most countries, but it's also useless given how many plastics etc are in modern braking systems.

Last time I checked, chlorinated CRC #05089 (tetrachloroethylene) is still available in most of the US (some states and Catalina Island excepted):

I bought several cans of it.  That said, I don't use it on PCB's.

Where do you think all that plastic is? The only plastic I've ever seen in the bit of a braking system that one would use brake cleaner on, the calliper and disc, is the rubber in the hoses and seals (generally EPDM rubber because they have to resist hydraulic oil).

I don't either. It does work very well for cleaning metal parts, as well as for removing stains from fabric. These operations should be done outdoors or with fume extraction.
