{"product_id":"rear-disc-brake-kit-long-spline-4x130mm","title":"Rear Disc Brake Kit, Long Spline, 4x130mm","description":"The EMPI Vented Rear Disc Brake Kit with Integrated E-Brake offers a significant upgrade in stopping power and thermal management for air-cooled classic vehicles. This kit replaces outdated rear drums with a modern disc setup, improving safety, reducing unsprung weight, and simplifying maintenance.\n\nPrecision engineered for functionality, this kit includes a 4 on 130mm lug pattern for proper wheel centering and is specifically designed for Long Spline applications, typically found on 1968 Swing Axle and 1968-1974 IRS transaxles. A key feature is the inclusion of dedicated emergency brake calipers, ensuring full e-brake functionality for street legality and practicality. The kit includes hardened mounting brackets, single-piston floating calipers with integrated mechanical emergency brake levers, high-friction brake pads, vented rotors, and e-brake cables.\n\n**Fitment:**\n*   VW Beetle (Type 1): 1968 (US Swing Axle models with long splines)\n*   VW Beetle (Type 1): 1968-1974 (IRS \/ Independent Rear Suspension models)\n*   VW Karmann Ghia: 1968-1974 (IRS \/ Independent Rear Suspension models)\n*   VW Super Beetle: 1971-1974 (IRS models)\n*   **Note:** Fits vehicles utilizing the \"Long Spline\" rear axle configuration.\n\n**Specifications:**\n*   Rotor Style: Vented (Dual-layer with internal cooling vanes)\n*   Bolt Pattern: 4 on 130mm (Late VW Pattern)\n*   Axle Fitment: Long Spline\n*   Material: High-grade cast iron rotors and heavy-duty steel brackets\n*   Weight: Approximately 60.75 lbs for the complete kit\n\n**Important Considerations:**\n*   **Master Cylinder:** Upgrading to a larger 20.6mm or 19mm \"Disc\/Disc\" master cylinder is highly recommended due to the increased fluid volume required by disc calipers. Ensure any residual pressure valves in the rear brake line circuit are removed.\n*   **Rotor Bedding:** Proper break-in procedure is critical to prevent warping or glazing. Perform a series of controlled stops, gradually increasing pedal pressure without coming to a complete stop during initial cycles.\n*   **Wheel Clearance:** Test-fit wheels before final assembly, as the caliper's physical profile is larger than a drum. Some early 15-inch steel wheels or aftermarket alloys with deep backspacing may require minor modifications or a small wheel spacer.","brand":"Empi","offers":[{"title":"Default Title","offer_id":52687947366712,"sku":"22-6144-0","price":742.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664707546.webp?v=1784887910","url":"https:\/\/store.motormia.co\/products\/rear-disc-brake-kit-long-spline-4x130mm","provider":"MOTORMIA","version":"1.0","type":"link"}
