ISR Performance Stainless Steel Front Brake Lines - Nissan 240sx - 300zx Z32 Conversion

The ISR Performance stainless steel front brake lines for the Nissan 240SX Z32 conversion solve the one detail most people forget when they bolt 300ZX front calipers onto an S13 or S14: the factory 240SX rubber hoses were never meant to meet a Z32 caliper. This set is built for that swap, so the line reaches the caliper banjo correctly and you are not improvising with adapters or mismatched fittings.

Why stainless on a Z32 brake swap

• Braided stainless steel jacket over the inner hose resists the swelling a rubber hose shows under hard pedal pressure
• Less hose expansion means more of your foot pressure goes to the caliper piston instead of into the hose wall
• Consistent pedal feel lap after lap, which matters more once the bigger Z32 calipers are generating real heat
• Stainless jacket shrugs off abrasion from debris and track grit better than a bare rubber hose

Application

Nissan 240SX with the 300ZX Z32 front brake conversion. These are the front lines only. ISR also offers a matching rear Z32 conversion set if you are converting both ends of the car.

Installation notes

Brake work is safety critical. Have the lines installed by someone comfortable with hydraulic brake systems, use fresh crush washers at every banjo, route the hoses along the factory path, and confirm full steering lock and suspension travel do not pull the hose tight before you bleed the system with fresh DOT fluid. Recheck every fitting for leaks after the first drive.
