ISR Performance Stainless Steel Rear Brake Lines - Nissan 240sx 89-98

The ISR Performance Stainless Steel Rear Brake Lines are the rear axle replacement brake line pair for the 1989-1998 Nissan 240SX (S13 and S14). PTFE inner core, stainless steel braided cover, and a yellow PVC outer jacket for additional abrasion and corrosion protection. CNC machined zinc plated fittings, permanently crimped. Sold as a pair for the rear axle.

What It Does

The factory rubber rear brake lines on the S13 and S14 expand under hard braking, which softens pedal feel and reduces stopping consistency. After two or three decades of heat cycling and ozone exposure, those rubber lines are also at the end of their service life on most 240SXs still on the road. The ISR stainless lines replace them with a braided assembly that doesn't expand under pressure and doesn't degrade from environmental exposure.

Net effect: firmer pedal feel, more consistent brake response, and a line that won't fail when you don't expect it. Critical for autocross, drift, and track use where rubber lines can be vulnerable to flying debris and repeated heat cycling.

Construction

• PTFE inner core (no volumetric expansion under pressure)
• Stainless steel braided cover (abrasion resistance, tensile strength)
• Yellow / gold PVC outer jacket (additional abrasion and corrosion protection)
• CNC machined zinc plated fittings, permanently crimped

Fitment

• 1989-1994 Nissan 240SX (S13) with stock rear calipers
• 1995-1998 Nissan 240SX (S14) with stock rear calipers

Designed for factory rear caliper installations. If you've upgraded to aftermarket rear calipers (Z32, big brake kits, etc.), verify line length and fitting compatibility before ordering.

Warranty

All ISR assembled brake line kits are backed by a lifetime warranty.
