{"product_id":"wilwood-120-13575","title":"Wilwood Type III Anodized FSL4R Thermlock Brake Caliper, 0.81-Inch Rotor Width","description":"\u003cp\u003eThis Wilwood Forged Superlite 4R is a 4-piston brake caliper with a Type III anodized finish for a nominally 0.81-inch-wide rotor. Its 5.98-inch radial mounting centers and 1.25-inch piston bores must match the brake assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.\u003c\/p\u003e\u003cp\u003eInternal fluid passages and radial mounting distinguish this four-piston Superlite. The selected piston design and bore sizes must match the brake balance calculation; they are not interchangeable merely because the mounting centers agree.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 120-13575\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Wilwood Forged Superlite 4R; one caliper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston arrangement:\u003c\/strong\u003e 4 pistons; 1.25-inch bores; Thermlock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic piston area:\u003c\/strong\u003e 2.46 square inches, as specified by Wilwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad shape:\u003c\/strong\u003e Wilwood type 7420; compound selected separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e universal side configuration; Radial; 5.98-inch centers; 0.39-inch mounting holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount height:\u003c\/strong\u003e 1.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor width:\u003c\/strong\u003e 0.81-inch nominal; 0.75–0.90-inch permitted range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor diameter range:\u003c\/strong\u003e 11.75–14.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid inlet:\u003c\/strong\u003e 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDust boots:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody and finish:\u003c\/strong\u003e Forged aluminum; Type III anodized\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eFor a replacement, compare the entire caliper specification rather than the finish or logo.
