Product Details

This ABS hydraulic assembly is part of Cardone’s remanufactured ABS Hydraulic Assembly line, which is engineered from failed-unit analysis to address original design weaknesses and restore dependable braking control. Part Number 12-2003 is intended for classic Chevrolet and GMC trucks where the ABS control module and hydraulic unit work together to manage wheel-speed input and brake pressure release during hard stops or low-traction events. If you are searching for a remanufactured ABS hydraulic assembly for a 1988-1990 Chevrolet C1500 or GMC K2500, this unit matches the listed applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Addresses

• ABS warning light triggered by module or hydraulic unit malfunction
• Brake fluid leakage from the ABS hydraulic assembly
• Loss of ABS function during abrupt braking
• Intermittent wheel-speed signal response affecting ABS operation
• Traction control or stability-system faults tied to ABS control failure

Installation Notes and Tips

Verify the part number and connector style before installation. Confirm the vehicle’s ABS diagnosis with scan data and inspect wheel-speed sensors and wiring, since contaminated sensors or damaged wiring can create ABS faults that mimic module failure. After installation, bleed the brake system according to the vehicle service procedure and clear any stored ABS codes.

Quality Assurance

Cardone remanufactures this ABS hydraulic assembly using reverse-engineering insight from failed units, then subjects each unit to automated functional testing, air-decay leakage checks, high-pressure hydraulic testing, and field validation. The result is a remanufactured brake component built to meet or exceed original equipment performance expectations for the listed Chevrolet and GMC truck applications.
