OEM-Spec Brake Master Cylinder for Infiniti/Nissan FM Platform ?

Restore strong, consistent stopping power with this hydraulic brake master cylinder. Built to factory dimensions, it keeps pedal feel firm and response predictable, matching the demands of performance-oriented Infiniti models.

Why this part is needed

Over time, internal seals harden, bores pit, and fluid absorbs moisture. That wear causes a soft pedal, longer braking distance, and warning lights. Replacing the unit returns correct hydraulic pressure and prevents damage to ABS components and calipers.

How it works ?️

When you press the pedal, a pushrod moves pistons in two separate circuits, converting force into hydraulic pressure. The reservoir feeds clean fluid, and the dual-circuit layout maintains braking if one side fails. It works with the ABS module to balance pressure to all wheels.

What happens if it’s broken ⚠️

Symptoms include a sinking pedal at stops, spongy feel, uneven braking, fluid leaks at the booster, and low-fluid alerts. Ignoring it risks sudden loss of braking performance and rotor/caliper overheating.

Pro tips for fitment ✅

Bench-bleed before install, use the correct DOT spec, torque lines evenly, inspect the booster gasket, and fully bleed all wheels. Clear ABS codes after service.
