In this review the SCITOO 18-B5030 disc brake caliper assembly is evaluated for owners of full-size GM SUVs and trucks who need a direct-replacement rear caliper. The bottom line: this caliper is for drivers who want a straightforward, OE-fit repair that restores braking performance without extra machining or modification. It delivers simple installation, a durable coated finish, and the expected stopping function for compatible Cadillac, Chevrolet and GMC models from the 2007-2017 era.

Key Features

• Vehicle Compatibility: Designed to fit a wide range of Cadillac, Chevrolet and GMC models from 2007 to 2017 so buyers can expect a direct fit on listed vehicles.
• Integrated Bracket: The caliper comes with the bracket included, which simplifies replacement and reduces the number of separate parts to source.
• Single Piston Design: The 1 piston, 2 in piston size provides consistent clamp force for rear applications on large SUVs and trucks.
• Standard Ports: Uses M10 x 1.0 inlet and bleeder ports to match common brake line and bleeding hardware for easier installation.
• Protective Coating: The caliper is coated to extend corrosion resistance and part life in typical road conditions.
• OE Fit Manufacturing: Built to precise OE requirements so replacement installs cleanly and minimizes adjustment time.

Who It's For

This caliper suits owners of Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe, and GMC Sierra or Yukon models across 2007-2017 who need a straightforward rear caliper replacement. It is especially appropriate for DIY mechanics and professional installers who value a part that arrives ready with its mounting bracket.

Those who should look elsewhere include drivers with non-listed model years or vehicles that require different piston configurations or special performance calipers; also buyers who need calipers with built-in parking brake actuators or premium multi-piston performance units.
