Product Details

Cardone Vacuum Power Brake Booster 53-6226 is part of the Cardone remanufactured brake booster line, which focuses on restoring original braking performance through re-engineering, inspection, and testing. This unit uses a dual 8.67-inch diaphragm design and is built from steel for dependable vacuum-assisted brake operation.

This part cross-references BMW 34336858064 for the same application.

What It Helps Address

• Hard brake pedal feel caused by a weak or failing booster
• Reduced vacuum assist during braking
• Brake response issues related to booster diaphragm wear
• Fitment problems from an incorrect replacement booster
• Corrosion-related booster housing deterioration

Installation Notes and Tips

Verify the vehicle is equipped for a vacuum power brake booster and matches the listed BMW ActiveHybrid 3 or BMW 330e fitment before installation. Confirm the master cylinder configuration, since this application is listed for vehicles lacking master cylinders. Follow the included instruction sheet, inspect the seal kit during installation, and check all vacuum connections and pedal linkage adjustment after the booster is mounted. The pre-adjusted output rod feature, when included, can help reduce setup time.

Each Cardone 53-6226 brake booster is 100% tested to confirm proper fit and function before release. The remanufacturing process is intended to restore O.E.-level performance while incorporating design improvements where applicable, and the rust-prohibitive finish adds protection for long-term service.
