Original brake lines are rubber and can expand under the normal pressure of use. This expansion of the brake line negatively affects the brake caliper piston travel, and makes for mushy pedal feedback.

UUC's Stainless Steel Brake lines are used to "performance tune" your braking system.

Inner Teflon® line is covered with woven stainless steel braid that will not expand under pressure. The advantages include better brake pedal feedback and a firmer pedal, along with superior brake modulation. Results will be immediate.

Technical features:

• fully compliant with DOT Standards (MVSS-1006)
  
  
• lines burst-tested to 6000psi
  (maximum tested pressure from a BMW braking system is 1200psi)
  
  
• Teflon® inner line covered with a woven layer of stainless steel
  and covered in an abrasion-resistant material (translucent blue plastic covering).
  
  
• plastic end pieces protect assembly, no exposed steel fibers to stick fingers.

Professional installation recommended.
