DuraGo BR31134 Disc Brake Rotor - Rear

DuraGo BR31134 Rear Disc Brake Rotor

The DuraGo BR31134 is a rear solid disc brake rotor built from cast iron for select Infiniti and Nissan applications. It is engineered for fit, form, and function using ISO-certified manufacturing standards, making it a direct replacement option for vehicles that need a conventional rear rotor service part.

Detailed Description

DuraGo BR31134 is a rear brake rotor for 1994 Nissan Maxima, 1995-2003 Nissan Maxima, 1996-2001 INFINITI I30, and 2002-2004 INFINITI I35. This rotor uses a solid, non-directional braking surface and a conventional drum-in-hat style is not used here, keeping the design straightforward for standard rear brake service. The cast iron construction supports consistent braking performance and a familiar OE-style replacement profile. This part cross-references Dorman - HELP 96511 for the same application.

What It Helps Address

• Rear brake pulsation from rotor wear or thickness variation
• Brake noise caused by an uneven or damaged rotor surface
• Reduced braking consistency from a rotor at or near discard thickness
• Corrosion-related service issues on an aging rear brake assembly
• Replacement needs for Nissan Maxima and INFINITI I30/I35 rear brake service

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, center bore, and rear-position fitment before installation. Clean the hub mounting surface thoroughly to help prevent runout concerns, and inspect pads, caliper hardware, and wheel bearings during brake service. For best results, measure rotor thickness after installation and confirm the brake pedal feel and parking brake operation where applicable.
