Case of 24 Liqui Moly - 20158 Brake Fluid DOT 5.1 Exceptionally well-suited for use with all disk and drum brake systems, as well as vehicle clutch systems for which a synthetic brake fluid of DOT 5.1specificationis required. The brake fluid is also suitable for use in ABS brake systems. Synthetic formulation based on glycol ethers, alkyl polyglycols and glycol ether esters which guarantees full function even during extreme conditions. A higher wet and dry boiling point compared to DOT 3 and DOT 4 brake fluids and unique inhibitors provide corrosion and oxidation protection at high temperatures. Special scavengers are used to suppress steam at increased moisture levels.
