Disc Brake Caliper Assembly Front Side Compatible with Select Cadillac

In this review the focus is on the A-Premium disc brake caliper assembly for the front side, a direct replacement intended for a wide range of Cadillac, Chevrolet and GMC trucks and SUVs. The bottom line is that this caliper is best for owners who need a reliable, factory-style replacement that fits heavy duty brake applications; it stands out for fitment coverage and a protective antirust coating that helps extend service life. The review draws on customer reports of solid fit, straightforward installation and generally good value while noting one mixed user comment about lockability.

Key Features

• Wide vehicle fitment: Fits numerous models including Escalade, Silverado, Tahoe, Sierra and Yukon XL, reducing the risk of ordering the wrong part.
• Two phenolic pistons: Uses two 2.003 in pistons for consistent braking performance and compatibility with specified GM brake code applications.
• Standard ports: M10 x 1.5 inlet and bleeder port sizes match OEM hardware for straightforward brake line and bleeding procedures.
• Antirust coating: A protective finish helps resist corrosion, which can prolong service life in road salt and wet conditions.
• Bracket included: Supplied with bracket for the front side, simplifying installation for technicians replacing the full assembly.
• One-year guarantee: Backed by a one-year unlimited-mileage warranty, offering reassurance after purchase.

Who It's For

This caliper assembly is aimed at owners and mechanics working on late-2000s to recent GM full-size trucks and SUVs who want a direct-fit replacement for heavy duty brake configurations. It is especially suitable for those replacing a damaged or seized front caliper on models listed in the fitment because customers report reliable fit and easier installation compared with more generic options.

Those who should look elsewhere are owners of vehicles not listed in the detailed fitment notes or shoppers who require calipers with built-in parking brake mechanisms or integrated electronic parking brake actuators, since this assembly is specified as a front side disc caliper with spreadfinger pad spring on certain applications and standard hydraulic ports.
