Achieve a flawless street legal rear disc conversion with EWO Cadillac El Dorado Brake Calipers (EWO E63013), the primary GM rear disc brake caliper for any GM 14 Bolt rear disc conversion, Dana 60 rear disc conversion, or Sterling 10.25 disc brakes project. These brand-new loaded rear brake calipers are high-performance JB6 GM rear calipers featuring a massive 2 15/16 inch piston and an integrated parking brake caliper mechanism to provide the rear disc parking brake holding power needed for 1 ton axle disc swap and 3/4 ton truck rear disc conversion builds. Perfect for SRW 14 bolt disc brackets, DRW rear disc conversion, or a Cab and Chassis disc brake kit, these zinc plated brake calipers replace the front GM K20 brake caliper or GM V20 brake caliper used on GM V20 truck brakes and include a 7 inch mounting pin spacing for a clean 14 Bolt disc brake swap. As the best off-road brake upgrade, this hydro-mechanical rear caliper set includes correct D122 brake pads with a brake pads with locking nub to engage the anti-rotation piston mechanism and prevent caliper piston rotating; a common failure in generic D122 vs D52 pads setups where the parking brake won't hold. Every off road brake calipers kit features a GM dual-bleeder caliper design for easier bleeding rear disc brakes, 7/16-20 banjo bolt sets (with 10mm x 1.5 banjo bolt options), and a heavy duty parking brake lever with a return spring. To eliminate a spongy pedal after disc swap, join the EWO Army brake parts community and ensure you perform pre-adjusting rear calipers via ratchet mechanism adjustment, Adjusting Eldorado parking brake systems correctly, and applying rear caliper slide pin lubrication. Complete your Chevy K20 rear disc upgrade by using steel braided brake lines, an adjustable proportioning valve, residual pressure valve removal, and a master cylinder upgrade for 4 wheel disc for maximum mechanical emergency brake caliper safety.
