ISR Performance Stainless Brake Conversion Line Kit - S13 S14 240SX To Z32 Rear

The ISR Performance Stainless Brake Conversion Line Kit is the rear brake line pair for 1989-1998 Nissan 240SX (S13/S14) builds that have been converted to Z32 (300ZX) rear calipers. Standard 240SX rear lines won't connect a 240SX hard line to a Z32 caliper, so this conversion-specific pair fills the gap with PTFE-core braided stainless construction. Sold in pairs.

What It Does

The Z32 brake conversion is one of the most popular bolt-on brake upgrades for the S-chassis platform, but the standard 240SX brake lines don't have the right fittings to connect to Z32 calipers. This kit provides the correct line and fitting combination to mate the factory 240SX hard lines to Z32 rear calipers in a clean OEM-compatible install. Designed to work with the OEM (240SX) hard brake line system, so no further chassis-side modifications are required.

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

• 1989-1998 Nissan 240SX (S13/S14) chassis
• Converting to Z32 (300ZX) REAR calipers
• Designed to work with the OEM 240SX hard brake line system

Front Pair

If you're doing a full front-and-rear Z32 conversion, pair these rear lines with the ISR Stainless Brake Conversion Line Kit - 240SX to Z32 FRONT (IS-N300ZX). Both pairs are needed for complete coverage.

Warranty

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