{"product_id":"wilwood-140-15978-rd","title":"Wilwood Red-Caliper Rear EPB Retrofit System for 0.81-Inch Rotor Width, Includes Electronic Controls and Wiring","description":"\u003cp\u003eRed motor-operated parking calipers and their control hardware form this rear EPB retrofit package for the specified 0.81-inch rotor thickness. The existing hydraulic brakes continue to handle normal service braking. A suitable custom bracket must position each parking caliper relative to the rotor and provide room for its motor through suspension travel. Rotors and application-specific mounts are not supplied with the controller and harness. From Camarillo, California, Wilwood Engineering develops disc-brake systems for street-performance, motorsport and specialized uses. Bill Wood founded the company in 1977. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form part of its range, and must be combined to match the demands of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-15978-RD.

Confirm caliper width, mounting-center spacing, rotor diameter\/contact position and clearance for the motors, wheels and suspension. Custom brackets are normally required and are not included. Retain a properly configured hydraulic service-brake system. The EPB is intended for static parking hold, not emergency stopping, and needs the documented electrical supply, fused wiring and controller installation.\u003c\/p\u003e\u003cp\u003eUse PMB Performance’s 20+ years of parts and fitment experience when checking a modified brake layout.
