Detailed Description

Cardone 54-71152 is a vacuum power brake booster built for GM compact truck and SUV platforms that require a JM7 brake code and a booster stamped CR or ZT, depending on model year. It is a remanufactured steel booster with a single diaphragm, M10x1.5 master cylinder stud thread size, and no master cylinder included. This part cross-references Chevrolet and GMC OE numbers 18010034 and 18014931 for the same application. Use it when replacing a worn booster on a Chevrolet S10, GMC S15, or related S-Series vehicle and you need OE-style brake assist restoration.

What It Helps Fix

• Hard brake pedal feel
• Reduced brake assist from a failing vacuum booster
• Brake pedal effort that has increased over time
• Brake system performance loss caused by internal diaphragm or seal wear
• Corrosion-related booster housing deterioration

Installation Notes and Tips

• Verify the vehicle’s Service Parts Identification sticker for brake code JM7 before ordering.
• Confirm the booster stamping matches the required CR or ZT application note for the model year.
• This part is listed without a master cylinder.
• Inspect the vacuum supply, check valve, and master cylinder condition during replacement.
• Follow the included instruction manual and confirm pushrod and mounting alignment before final assembly.

Quality Assurance

Each Cardone remanufactured brake booster is re-engineered and 100% tested to meet OE-style performance expectations. The unit is built with OE-quality seals and check valves, and the corrosion-resistant finish is used to help extend service life.
