Every time you brake, some of the mechanical energy put into the pedal is wasted expanding the stock rubber brake lines on your car. This causes a spongy brake pedal and loss of some initial braking power. SportTune your braking system with stainless steel braided Teflon brake lines from Autotech. Because Teflon hose wrapped in stainless steel braid does not expand like ordinary rubber hose, these lines provide quicker brake response and a firmer pedal.Autotech's SportTuned Brake Lines feature billet stainless steel ends, instead of the normally used carbon steel. This exclusive design ensures absolutely corrosion-free performance. Autotech SportTuned Brake Lines are direct replacements for the original rubber hoses and do not require adaptors. Absolutely the best available.
