Product Details

The Cardone 54-71140 power brake booster uses a single diaphragm design and a 10.38-inch diaphragm diameter to support vacuum-assisted braking performance. It features a steel housing, M10x1.5 master cylinder stud thread size, and a gray finish. The booster is remanufactured, then tested to confirm proper operation before shipment. This part cross-references Chevrolet 18010579 and GMC 18010579 for the same application.

Common Brake Assist Problems It Can Address

• Hard brake pedal feel
• Reduced vacuum brake assist
• Inconsistent pedal response during braking
• Brake booster leakage or internal diaphragm wear
• Fitment issues when replacing a worn OE booster on GM trucks

Installation Notes

Compatible With 1981-1986 Chevrolet C10, N/A, and 1981-1986 GMC C1500, N/A. Also compatible with 1987 Chevrolet R10, N/A, and 1987 GMC R1500, N/A. Fitment requires JB3 brake code verification and confirmation of the GM brake code on the Service Parts Identification sticker. The booster does not include a master cylinder, so the existing master cylinder must be reused or sourced separately as needed. Verify vacuum line condition, mounting alignment, and master cylinder pushrod setup during installation.
