{"product_id":"wilwood-130-10536","title":"Wilwood DH4 Square Caliper Piston Seal Kit, Two-Pack, 1.300\/0.740-Inch Inside Diameters","description":"\u003cp\u003eThis DH4 service kit contains two square-section seals with listed inside diameters of 1.300 and 0.740 inch. Wilwood’s nominal DH4 piston designation is separate from these physical seal dimensions. The two different ring sizes must be matched to the correct locations in the appropriate stepped-piston caliper arrangement. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 130-10536\u003c\/li\u003e\n\u003cli\u003eService component: Caliper Square Ring Kit\u003c\/li\u003e\n\u003cli\u003eSeal profile: Square-Ring\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed seal inside diameters: 1.300 \/ 0.740 inches\u003c\/li\u003e\n\u003cli\u003eListed seal thickness: 0.099 inch\u003c\/li\u003e\n\u003cli\u003eManufacturer material code: 210M\u003c\/li\u003e\n\u003cli\u003ePack quantity: 2 Pack\u003c\/li\u003e\n\u003cli\u003eSeal fluid compatibility: DOT 3, DOT 4 and DOT 5 as specified for these seals.
