A common failure point in custom rear disc brake conversion projects is the compromise made on the emergency brake. Most builders are forced to choose between a high-performance caliper or a salvaged mechanical unit that often fails to hold. The EWO Cadillac El Dorado Brake Calipers eliminate this compromise, offering a heavy-duty, brand-new solution for GM truck owners who demand both stopping power and stationary security. These calipers are engineered to handle the weight and torque requirements of 1-ton axle conversions while providing a clean, integrated mechanical lever. Whether your rig is a dedicated rock crawler or a heavy-duty tow rig, the ability to lock your rear rotors independently of your hydraulics is a vital safety requirement. Technical Overview and Vehicle Compatibility The East West Off Road brake calipers are designed as a direct-fit replacement for the massive front calipers found on ’73–’86 GM K20 and ’87–’91 GM V20 trucks. These specific vehicle platforms are the industry standard for 14-bolt and Dana 60 rear disc swaps. Performance Features 100% Brand-New Construction: Every component is new, ensuring no internal pitting or seal degradation often found in remanufactured cores. Clear Zinc-Plated Finish: Specialized coating to resist the corrosive effects of mud, salt, and grime. No Core Charge: Avoid the hassle and expense of shipping heavy cast-iron cores back to a manufacturer.

By utilizing the Cadillac El Dorado style internal ratcheting mechanism in a brand-new casting, these units provide the correct piston area for GM master cylinders. This ensures your brake pedal feel remains firm and predictable. Unlike rebuilt "parts-store" units, these Cadillac El Dorado brake calipers are manufactured with fresh internals to prevent the common "sticking" issues associated with old parking brake mechanisms. Performance Features 100% Brand-New Construction: Every component is new, ensuring no internal pitting or seal degradation often found in remanufactured cores. Integrated Parking Brake: A robust, mechanical parking brake caliper design that provides a physical lock on the rotor. Clear Zinc-Plated Finish: Specialized coating to resist the corrosive effects of mud, salt, and grime. No Core Charge: Avoid the hassle and expense of shipping heavy cast-iron cores back to a manufacturer. Components Included in the Kit This product is a complete axle-set solution, including: (1) Driver-side park brake caliper (1) Passenger-side park brake caliper (1 pair) D122 brake pads (1 pair) 7/16-20 banjo bolts with copper sealing washers Use Case: Trail Safety and Street Compliance On the street, maintaining a functional parking brake is a legal requirement in most jurisdictions. The EWO system allows you to meet these safety standards without cluttering your axle with secondary "spot" calipers or expensive driveline brakes. The clear zinc plating ensures that even after seasons of salt and mud, the mechanical remains operational and free of rust. FAQ Are these Cadillac El Dorado brake calipers rebuilt or new? These are 100% brand-new calipers. Unlike many options on the market, they contain no rebuilt components and require no core charge, ensuring all internal mechanisms are at factory-new tolerances. Will these fit my GM K20 or V20 rear disc conversion? Yes. These calipers are a direct replacement for the front calipers used on ’73–’86 GM K20 and ’87–’91 GM V20 trucks, which are the standard units used in most heavy-duty rear disc conversion brackets. What is included in the EWO package? The kit includes both driver and passenger-side calipers, a full set of D122 brake pads, and 7/16-20 banjo bolts with copper sealing washers for a complete installation. Why is the clear zinc finish important for off road brake calipers? Off-road vehicles are frequently exposed to moisture, mud, and debris. The clear zinc plating provides a protective barrier that prevents corrosion, ensuring the parking brake lever moves freely and the caliper maintains its professional appearance. Do I need a core to purchase these GM rear disc brake caliper units? No. Because these are brand-new manufactured parts, there is no core charge or exchange required. You can keep your old parts or start your build from scratch without additional fees.
