USP Stainless Steel Rear Brake Lines- Audi B8 A4/A5/S4/S5

Stainless steel brake lines replace your factory rubber lines and provide more consistent braking. Your car's brake system operates at over 1,000psi under hard braking conditions; the factory rubber lines cannot perform and begin to expand. This leads to a "spongy" brake pedal or a slight delay in brake engagement. This can be catastrophic when driving in spirited race conditions. Stainless steel brake lines replace these factory lines and with a stainless steel woven exterior, these lines will not expand even under the harshest conditions.All USP brake lines are a direct replacement for the factory brake lines and can be installed in just a few hours.
