ISR Performance Brake Line Kit - Nissan 370Z 09-13 Standard Brakes

The ISR Performance Brake Line Kit for the 2009-2013 Nissan 370Z with standard (non-Akebono) brakes is the full stainless-braided replacement set for the factory rubber lines. PTFE core, stainless braid, the standard upgrade for a 370Z on standard brakes that needs a firmer, more consistent pedal feel. Comes with all the OEM-replacement banjo bolts and adapters needed for the install.

What It Does

Factory rubber brake lines expand under braking pressure, which softens pedal feel and reduces precision in modern brake systems. Stainless braided lines eliminate that expansion entirely, giving you a noticeably firmer pedal with more consistent braking force, especially under sustained track use. This kit covers all four corners and includes the necessary OEM-replacement adapters and banjo bolts.

Fitment

2009-2013 Nissan 370Z with standard (non-Akebono) brakes only. Will NOT fit 370Z models with the Akebono brake package. for those, see IS-NIS-1338 (2009-2010 Akebono fitment only). Caliper-side fittings differ between the two brake packages, so ordering the right kit matters.

Installation Notes

Brake line installation should be done by a professional mechanic. Key points:

• Use the new crush washers supplied in the kit
• Do not mix rubber hoses and stainless steel lines on the same brake system
• Do not force, rotate, or stretch any stainless steel hose assembly during install. this can cause failure
• Tighten banjo bolts and fittings to the manufacturer's torque spec, or 12-14 ft-lbs if no spec is available
• Check that hoses are not kinked or twisted, and verify full clearance through suspension and steering travel
• Bleed the system with fresh DOT-approved brake fluid per the vehicle's spec
• Recheck all lines and connections for tightness and leaks after the first 100 miles
