Product details
The black FNSL4R/MC4 package separates the 240SX's hydraulic braking from mechanical parking-brake actuation. Four-piston service calipers, BP-10 pads and 13.50-inch GT discs are supplied with dedicated MC4 parking calipers and 12-inch rear flexlines. Wilwood Engineering, based in Camarillo, California, has designed and manufactured disc brake systems since its founding by Bill Wood in 1977. The range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

Fitment & Compatibility
Fits the 1989–1998 Nissan 240SX rear applications in the table, with the listed four- or five-lug and ABS configurations. Separate MC4 calipers provide the mechanical parking brake. The included rear flexline kit is 220-18269, 12 inches long. Factory parking-brake cables do not connect to the MC4: order cable kit 330-18324 for 1989–1994 or 330-18325 for 1995–1998 separately. Match the hub register, and follow the caliper and cable-adjustment instructions. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
