Description
The Wilwood Superlite 4R Rear Electronic Parking Brake Kit (manufacturer part number 140-15844-R; Summit Racing part number WIL-140-15844-R) is a rear disc brake kit for applicable Big Ford New Style/Torino axle housing flanges measuring 3.562 x 2.00 inches. It is designed for rear applications that need an integrated parking brake; confirm axle and wheel fitment before ordering.
The kit includes red forged billet-aluminum Superlite 4-piston rear calipers, BP-10 brake pads, and vented rear rotors with a solid surface. The included rotors measure 12.88 inches (327.15 mm) in diameter and 1.11 inches thick. Their bolt pattern is triple-pattern: 5 x 4.50, 5 x 4.75, and 5 x 5.00 inches (5 x 114.30, 5 x 120.65, and 5 x 127.00 mm).
An electric-caliper parking brake provides static holding power without mechanical parking-brake cables. A control unit and harness assembly are supplied to support installation and operation. Wilwood describes the kit as a rear-brake option for custom, show, and high-performance street machines, including builds complementing a front big-brake upgrade.
