Keep your rear brakes turning true with the PowerStop Disc Brake Rotor JBR504, a direct-fit rear rotor for the 1989-1998 Nissan 240SX. It provides a fresh, flat friction surface for the rear brake pads to clamp against, helping restore smooth, even braking when the original rotor is worn, scored, or has run below its minimum thickness.
- Rear position: cataloged as a rear disc brake rotor for the listed 240SX application.
- Direct-fit replacement: a direct-fit replacement for the listed application.
- Renewed braking surface: a clean rotor face gives the pads consistent contact for balanced stops.
Signs a rotor may need replacing include brake pulsation or steering-wheel/pedal vibration under braking, deep scoring or grooves, and thickness worn past the manufacturer's minimum. If a worn or damaged rear rotor is the cause of these symptoms, this replaces it. Rotors work as a matched pair on an axle, so replacing both rear rotors together is recommended for even, balanced braking; this listing is for one rotor, sold individually — order two for a complete rear-axle job. Have the rotor inspected and installed per the vehicle service procedure.
Interchange: Manufacturer part number JBR504.
