MPA Electrical B3227 Power Brake Booster

Reman Vacuum Brake Booster for Kia Sportage

MPA Electrical B3227 is a remanufactured vacuum power brake booster for 1998-2002 Kia Sportage applications. It is built for standard replacement service and is designed to restore braking assist with lower pedal effort in the Kia Sportage brake system.

Product Details

MPA Electrical B3227 is engineered for Kia Sportage brake repair where vacuum assist has weakened or the booster has failed. The remanufactured design uses specially treated replacement components to support vacuum sealing and pressure transfer, helping the brake pedal feel more consistent during normal driving and stop-and-go use. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

The MPA Electrical brake booster line focuses on remanufactured replacement units that are tested before shipment. For Kia Sportage owners searching for a reman vac pwr brake booster w/o master cyl, B3227 provides the correct booster-only format when the master cylinder is being reused or replaced separately.

Common Problems This Part Can Address

• Hard brake pedal feel
• Reduced vacuum brake assist
• Longer stopping distance caused by booster loss
• Brake pedal effort that increases during normal driving

• Inspect the master cylinder, vacuum hose, and check valve during replacement.
• Confirm the 2-stud mounting pattern and 8 x 1.25 mm master cylinder thread size match the original unit.
