The use of stainless braid protected teflon brake hose assemblies will result in a firmer brake pedal, improved brake pedal ?feel? and better brake modulation. Since brake actuation produces high pressure with very little fluid displacement, we recommend -2 & -3 SPEED-FLEX? for brake systems. Clutch actuation, on the other hand, requires moderate pressure but considerable displacement of fluid. For hydraulic clutch systems we recommend the use of -4 SPEED-FLEX?. In recent years various fuel manufacturers have added any number of new unpublished additives to their blends rendering some of them incompatible with synthetic rubber lined hose. Earl?s Speed-Flex? Teflon? lined stainless braided hose is impervious to any automotive fuel blend known to us and may be the best choice for use with modern racing fuels. All SPEED-FLEX? hoses are compatible with petrol, hydrocarbon fuels, alcohols, nitro-methane, mineral and synthetic lubricants, and high density fuel additives. Size 6 and 8 are carbon lined to dissipate static electricity.
