Detailed Description

Cardone 18-B4798 is a remanufactured front left brake caliper engineered for vehicles that use a phenolic piston design and bracketed caliper assembly. It is a direct-fit replacement for 2002-2005 Chevrolet Trailblazer EXT, 2003-2005 Chevrolet Trailblazer, 2003-2005 Chevrolet SSR, 2002-2005 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2003-2005 Isuzu Ascender, 2004-2005 Buick Rainier, and 2005 Saab 9-7x. This part cross-references OE numbers such as Buick 88966985 and Chevrolet 88964428 for the same application.

The Cardone brake caliper remanufacturing process replaces wear items with new premium components and pressure-tests each unit for brake performance and sealing integrity. The result is a service-ready caliper assembly with the bracket included where applicable, making it a practical choice for restoring front brake function on the Trailblazer, Envoy XL, and related platforms.

What It Helps Fix

  • Brake pull to one side during braking
  • Low brake pedal caused by caliper-related hydraulic issues
  • Uneven front brake wear
  • Sticking or seized caliper operation
  • Brake fluid leakage at the caliper body or bleeder area

Installation Notes and Tips

Use the OE-specified brake fluid listed on the master cylinder reservoir cap and always fill with fresh fluid from a sealed container. For floating caliper mounting pins, use silicone grease. Bleed the brake system thoroughly after installation and inspect hoses, pads, and related hydraulic components before returning the vehicle to service.
