Product Details

MPA Electrical B1207 is a remanufactured power brake booster engineered to restore braking assist with minimal pedal effort. The unit is tested at the end of production using proprietary equipment, and its replacement components are treated to support vacuum sealing and pressure transfer. For Saturn brake system service, B1207 provides a direct-fit vacuum booster solution for the listed SC1, SC2, SL, SL1, SL2, and SW2 applications.

This part cross-references 21013196 for the same application. If you are replacing a worn booster on a Saturn SC2 or Saturn SL, confirm the master cylinder interface and mounting points before installation. The B1207 part number is useful when matching the correct booster configuration for Saturn brake repair.

Common Uses

• Restoring brake assist when pedal effort has increased
• Replacing a booster with vacuum leakage
• Addressing poor pressure transfer in the brake system
• Correcting brake feel issues caused by booster wear

Installation Notes

Verify the booster type, diaphragm size, and master cylinder stud thread size before installation. This unit does not include a master cylinder, gasket, seal, mounting bracket, or pedal rod extension.
