Product Description

The PowerStop S4854 rear caliper pair offers a direct-fit upgrade for 2003-2007 Chevrolet Silverado 1500, 2003-2007 GMC Sierra 1500, 2003-2005 Cadillac DeVille, and 2006-2011 Cadillac DTS models. Built with OEM-grade cast iron bodies and a single phenolic piston (~54.1 mm), each caliper is cleaned, refurbished, and pressure-tested in PowerStop's Chicago facility to ensure dependable performance and leak resistance.

These high-temp red powder-coated calipers add both durability and visual flair behind stock or aftermarket wheels. The kit includes all required hardware for bolt-on rear installation: slides, bleeder screws, seals, boots, guide pins, and stainless abutment clips. Premium silicone lubricant is pre-applied for smooth movement under load. Designed exclusively for rear floating brake configurations.

Fitment confirmed through **2011**; no listings support coverage in 2025. This kit suits vehicles originally equipped with single-piston rear floating calipers only. Not compatible with integrated parking brake calipers or dual-piston rear brake systems. Always confirm your vehicle's brake caliper type before purchase.
