Abstract
The compositions include a methylated siloxane liquid and a solvent comprising at least one of a ketone or ester each having up to six carbon atoms, a halogenated alkane having up to two carbon atoms, tetrachloroethene, 1-chloro-4-trifluoromethyl benzene, or ethane. The compositions can also include hydrocarbon solvent comprising at least one of toluene, xylene, or a saturated hydrocarbon represented by formula CxH2x+y, wherein x is from 5 to 8, and wherein y is 0 or 2 and/or propellant. The method can include applying the composition to a brake system component to clean the brake system component. The method can also include applying a composition including hexamethyldisiloxane to a brake system component to clean the brake system component.
