    Improve vehicle brake performance and feel with StopTech Stainless Steel Braided Brake Lines.

    StopTech Stainless Steel Braided Brake Lines provide a quicker, firmer, more consistent pedal response by maintaining consistent brake pressure. Additionally, stainless steel lines provide precision brake modulation, especially during threshold braking. The improvement in pedal feel is more dramatic on older vehicles where the factory rubber line may have softened and swelled due to age.

    StopTech brake lines consist of a Teflon inner line that carries the brake fluid. A substantial woven stainless steel braid forms the structure. The Teflon liner is very resistant to expansion from pressure and will not degrade from exposure to brake fluid.

    The braided stainless steel provides support for the PTFE and the weave is extremely durable against incidental impact and abrasion. The braid is covered with a clear PVC. The outer coating provides maximum protection against chaffing. End fittings have integrated strain relief devices as further reinforcement.

    A variety of end fittings are available to meet most application needs. Exact fit fittings and new hardware are included with each kit.

    StopTech SS Front Brake Lines for 08-21 WRX/STi lines are all tested to 4,500 PSI. Four times the line pressure a production vehicle’s master cylinder produces.
