Product Details

Cardone’s Vacuum Power Brake Booster line focuses on remanufactured brake assist components that are re-engineered, inspected, and tested to meet original equipment standards. This Cardone 54-71135 booster is built for the 1969 Pontiac Firebird, and the application notes specify vehicles lacking master cylinders. The package includes the booster and an instruction manual.

Common Brake Assist Issues It Can Address

• Delayed or inconsistent brake response
• Loss of braking boost caused by a worn diaphragm or internal seal wear

Installation Notes

Verify the vehicle application before installation: Fits 1969 Pontiac Firebird, N/A. Confirm the booster style, diaphragm diameter, and master cylinder interface match the original setup. The master cylinder is not included, so transfer or verify related brake system components as needed during service. Follow the included instruction manual and check vacuum connections, pushrod adjustment, and pedal operation after installation.
