When servicing your vehicles brake system, it's a good idea to make sure everything is left clean and grease free. The Liqui-Moly Rapid Brake & Parts Cleaner helps dissolve brake dust, oil, grease, grime and resin fast without a trace. Parts are left totally cleansed of all oil and grease based contaminants. As an aerosol it can be precisely sprayed on areas requiring cleaning. Using a brake cleaner during a brake service minimises the risk of disc brake squeal. It can be applied without disassembly of brakes and dries fast & leaves no residue.
