ISR Performance Brake Line Kit - Nissan 350Z 02-07

The ISR Performance brake line kit for the 2002 to 2007 Nissan 350Z replaces all four factory rubber hoses in one go. It is intended for the Z33 with the standard (non-Brembo) brake package and gives a stock-caliper 350Z the firmer, more consistent pedal that comes from hoses that no longer swell under pressure.

Why replace all four at once

Rubber hoses soften with age and heat, and every bit of expansion is pedal travel you feel as mush. Doing the fronts alone leaves half the system on old rubber, which is why ISR supplies the full set along with the hardware.

What's in the box

• 2 front brake lines
• 2 rear brake lines
• 4 banjo bolts
• 8 crush washers
• Installation instructions

Every kit ships with the OEM-style replacement adapters and banjo bolts needed for the job.

Fitment

Nissan 350Z, 2002 to 2007, standard brake calipers. Z33 models equipped with Brembo brakes use a different ISR kit.

Installation guidance

Brake line installation should be done by a professional mechanic. Read the included instructions completely. In brief: raise the car, remove the wheels, drain the fluid, and note C-clip and banjo positions as the old lines come off. Clean all sealing surfaces, fit the new lines from the caliper along the OEM path with the supplied crush washers, seat every tab and bracket so there is no tension at either end, and confirm the hoses are not kinked, twisted, stretched or trapped through full steering and suspension travel before final tightening. Hold hard lines with the correct wrench, torque to the manufacturer's spec (or 12 to 14 ft-lbs), then bleed with fresh DOT fluid per the manufacturer's procedure.

Warning: check every connection for leaks and confirm a firm pedal before test driving, and recheck all lines after the first 100 miles. Do not mix rubber hoses and stainless steel lines on the same system, and never force, rotate or stretch a stainless hose assembly; it may cause failure.
