The Effect of Silicone Brake Fluid on Rayon Reinforced, Neoprene Tube and Cover Brake Hoses

Laboratory and field testing of silicone brake fluid, over a period of twelve years, has shown no adverse effects on braking systems while many advantages are apparent.

The near complete conversion by the American Automotive Industry, to rayon reinforced, neoprene tube and cover brake hoses caused some concern with the compatibility of silicone fluid and this type hose.

Data is presented comparing conventional fluids and silicone fluid and the effect of each on hoses from several manufacturers.
