The selected red calipers use 4 service pistons each; matching the factory or specified conversion hardware is essential to the complete installation. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc-brake systems for motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must match the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 140-17120-DR; supplied as an axle kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParking brake:\u003c\/strong\u003e Internal shoe parking brake supplied; cables, cable hardware and adapters are separate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor specification:\u003c\/strong\u003e Material: Iron; Type: SRP Drilled Rotor \u0026amp; Hat; Style: SRP Drilled \u0026amp; Slotted; Surface Finish: Black Electro Coat.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied friction pads:\u003c\/strong\u003e BP-10 compound; match operating conditions to the intended use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService calipers:\u003c\/strong\u003e Forged Dynapro Low Profile; 4 pistons per caliper; Red Powder Coat; lug mounting; stainless pistons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware and retained components:\u003c\/strong\u003e Mounting hardware supplied; existing wheel hubs retained; spindles, master cylinder and brake booster are not included.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic sizing:\u003c\/strong\u003e cataloged bore sizes 1.38, 1.38 inches; piston area 3.00 square inches; inlet 1\/8-27 NPT.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake rotor size:\u003c\/strong\u003e 11.00-inch outside diameter × 0.81-inch thickness; vented friction section.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic lines:\u003c\/strong\u003e Hydraulic flexlines and fittings are not included; select compatible lines for the complete installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachining prerequisite:\u003c\/strong\u003e Housing-flange material removal and two drilled holes required; follow the specific drawing and arrange qualified machine-shop work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor\/hat mounting-hole pattern:\u003c\/strong\u003e 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm; cataloged hole clearances 0.52 in; 13.21 mm.
