Front Right Brake Caliper With Bracket 18-B4728 - Direct Fit

In this review of the front right brake caliper 18-B4728, the bottom line is simple: it is a practical, budget-friendly replacement for owners of large GM SUVs and trucks who need a dependable passenger-side caliper that bolts on with minimal fuss. The reviewer found it especially appealing for those repairing Escalade, Silverado, Sierra, Tahoe, Suburban, Yukon or H2 models from the years listed because the caliper matches common OEM dimensions and uses a phenolic dual-piston design that balances stopping power with heat resistance. This review focuses on fit, build, and real-world installation notes.

Key Features

• Direct fit coverage: Fits a long list of Cadillac, Chevrolet, GMC and Hummer models from late 1990s through early 2010s, reducing compatibility guesswork for common GM platforms.
• Brake caliper specification: Identified as 18-B4728 for the front passenger side, so buyers get the correct side and location without modifications.
• Piston design: Uses two phenolic pistons that resist heat and help maintain braking responsiveness under normal driving conditions.
• Ports and threads: Bleeder and inlet port sizes are M10 x 1.5, matching many factory brake hose and bleeder fittings for straightforward plumbing.
• Built to OEM standards: Manufactured to meet or exceed OEM specifications, offering buyers a reliable alternative to factory-priced units.
• Bracket included: Ships with a bracket to simplify installation and ensure proper caliper alignment on the knuckle.

Who It's For

This caliper is best for do-it-yourself mechanics and independent shops working on compatible GM full-size SUVs, pickup trucks and Hummer H2 models that match the listed years. It will suit owners who want a cost-effective replacement that provides good stopping power and straightforward installation without needing custom work.

It is not aimed at owners seeking high-performance racing upgrades or precision track components; for aggressive track use or custom vehicles outside the listed fitment, a heavy-duty or performance caliper engineered specifically for that purpose would be more appropriate.

Pros & Cons

Pros

• Solid build quality and reliable functionality reported by users, delivering acceptable stopping power and durability.
• Easy to install with included bracket and compatible M10 x 1.5 ports, saving time during replacement.

Cons

• Some buyers reported occasional caliper sticking on similar aftermarket units, so proper bedding and inspection are recommended during installation.
• Piston material is phenolic, which is common and effective, but may not satisfy those seeking metal pistons for extreme-duty applications.
