Rear Left & Right Brake Calipers w/Bracket for Escalade Silverado

In this review the focus is on a pair of rear left and right brake calipers with brackets designed for a long list of GM full-size SUVs and trucks. The bottom line: these calipers are for owners who need a direct replacement that matches original mounting and port sizes and want a cost-effective rebuild without changing rotors or lines. Fitment is the strongest selling point-this review finds they install cleanly on compatible Cadillac, Chevrolet and GMC models and restore solid braking feel when paired with correct pads.

Key Features

• Direct fitment: Designed to match factory mounting and brake line ports so installation is straightforward on listed Cadillac, Chevrolet and GMC models.
• Brake piston design: Dual 1.773in phenolic pistons reduce heat transfer to brake fluid and help maintain consistent stopping under normal use.
• Bleeder and inlet ports: Comes with a 5/16-24_UNF bleeder port and M10X1-6H inlet port to match OEM hydraulic connections.
• Included bracket: Bracketated pair means the driver and passenger sides are supplied together for complete rear axle service.
• Value proposition: Customers note improved functionality and return to factory feel at a lower cost than dealer replacement units.

Who It's For

These calipers are aimed at owners and independent mechanics working on 2000s-era GM full-size trucks and SUVs who need a like-for-like replacement for the rear axle. They are particularly suited to those servicing Cadillac Escalade models (2002-2006) and a wide range of Chevrolet and GMC Silverado, Sierra, Tahoe, Suburban, Yukon and Avalanche variants listed in the fitment notes.

Owners with late-model vehicles not listed, or those who require upgraded performance calipers (larger pistons, multi-piece designs, or different materials) should look elsewhere. Also check your vehicle MAKE/MODEL/TRIM carefully before purchase to ensure correct compatibility.
