Property me this means bought to degrease the discs of my hydraulic Bemsanlage the bicycle and thus eliminate the last bit of squeaking. Tcha, it is exactly the opposite happens. The brake discs shine But now they squeak like crazy. I'm very disappointed. If you rub the cleaner between your fingers, you tend to feel there is a kind of oil ... ?? - What I think is a brake cleaner for illogical. I think this has ultimately also meant that my brakes squeak. Then the title of this product, however, is really meant only for car brakes - but you should then also as mentioned in the product description.
