Jim, it looks like Coleman fuel has a lower octane rating (at 50-55) than does your Fuelite at an octane rating of 65, provided the different countries do rate octane the same. I also can find no reference for using Coleman fuel as a brake cleaner, though I have often used it as a cleaner of various petrochemical gums, gunks and scums, so it would likely work to some degree.
I would say that while they are likely quite similar products, I would also have to say that they are at least slightly different products, though their range of uses clearly overlap.
On an off note, I would say from experience, that a gallon can of Coleman fuel can be used as a crush space cushion to a certain degree, though I am more than certain that is not a manufacturers' recommended usage!!!
