Wilwood 140-18296 XRS4R Rear EPB Big Brake Kit 14.00in Slotted Rotor Black

The Wilwood 140-18296 is an XRS4R rear big brake kit with an electric parking brake (EPB). It has 14.00-inch slotted rotors with a 2.50-inch offset and black powder-coated 4-piston calipers. It is built for street performance and replaces the factory rear brake and internal drum parking brake assembly on compatible Big Ford 9-inch rear axles.

Key Features:

• XRS4R X-Bridge caliper: the four-piston version of Wilwood's X-Bridge street caliper, which Wilwood says is stronger and lighter than the Forged Narrow Superlite (FNSL) radial-mount caliper it succeeds.
• Stainless steel pistons with square O-ring design: better heat barriers, longer component life, and improved pedal feel.
• 14.00-inch slotted rotors: black E-coated Spec37 iron alloy in a GTB slotted design, with 72 curved internal vanes.
• 2.50-inch rotor offset: sized for the kit's rear-axle layout.
• Electric parking brake: Wilwood's EPB caliper replaces the internal drum assembly. The kit includes the wiring harness, control unit and remote switch.
• BP-10 brake pads: street-performance pads are included, and other compounds are available for most applications.
• Black powder-coat finish: a durable, clean look behind the wheel.

This Wilwood rear disc brake upgrade adds stopping performance and heat management over stock drum or small-disc setups. It also keeps a fully functional parking brake.
