When I opened this lube, I noticed that the product is actually purple! It doesn't add or decrease lubrication, but it was interesting to see on a brake product. If you use a good, even foil, one blister should be enough for 2 horseflies. If you save you can do all four with one pack, but I always err on the side of excess and used one pack per turn when doing my brakes. Just remember that during installation they must not get on the braking surfaces and not on the actual surface of the brake pad or the surface of the brake disc. If you get on these surfaces I recommend using brake cleaner to remove the grease.
