Low VOC content brake cleaner compositions useful for removing oil and particulate contamination from braking system components of vehicles such as automobiles are reported. The brake cleaner compositions comprise about 5 % to about 30 % by weight methyl acetate; about 25 % to about 50 % of a hydrocarbon according to the formula (I) CnH2n+x, where n is 5 to 8 and x is 0 or 2; and about 25 % to about 55 % by weight acetone.
L'invention concerne des compositions de nettoyage de freins à faible teneur en composés organiques volatils, utiles pour éliminer l'huile et des contaminants particulaires à partir des composants du système de freinage de véhicules, tels que des automobiles. Ces compositions de nettoyage de frein comprennent environ 5 à environ 30 % en poids d'acétate de méthyle, environ 25 à environ 50 % d'un hydrocarbure correspondant à la formule C¿n?H¿2n+x?, dans laquelle n vaut entre 5 et 8, et X vaut 0 ou 2, ainsi qu'environ 25 à environ 55 % en poids d'acétone.
