Detailed Product Description

This power brake booster features a metal housing designed to withstand the rigors of daily driving and brake system demands.

Installation Notes and Tips

Ensure the brake system is depressurized before removing the old booster. Verify compatibility with your vehicle’s make and model, specifically Chevrolet Firefly, Geo Metro, Pontiac Sprint, or Suzuki Swift. Since this booster does not include the master cylinder or mounting hardware, retain or replace those parts as necessary. Properly torque mounting studs to manufacturer specifications and check for vacuum leaks after installation.

This MPA Electrical power brake booster is remanufactured to meet standard brake service grade requirements, ensuring reliable performance.
