Product Details

Cardone Vacuum Power Brake Booster 54-74436 is part of the brand’s remanufactured brake booster line, which focuses on restoring original brake assist performance through re-engineering, inspection, and testing. This unit uses a single diaphragm layout and is built from steel for durability. Cardone also applies a rust-resistant finishing process and pre-adjusts master cylinder output rods when included, helping streamline installation and maintain proper brake system operation. This part cross-references GM OE part number 20896308 for the same application.

What It Helps Address

• Hard brake pedal feel caused by a weak or failing booster
• Reduced brake assist during normal stopping
• Vacuum-related brake performance loss
• Brake system fitment issues on vehicles requiring a replacement booster
• Noise or inconsistent pedal response from a worn booster assembly

Installation Notes

Verify brake code and application details before installation, especially on 2010-2011 Chevrolet Silverado 1500 and GMC Sierra 1500 models with JD9 brake code or 2010 models with Active Brake Control. This booster is for vehicles without a master cylinder, and the master cylinder is not included. Confirm the master cylinder stud thread size is M10x1.5 and follow the included instruction manual during installation.
