Detailed Description

MPA Electrical B3515 is a remanufactured power brake booster engineered to restore vacuum-assisted braking performance. The unit is built to transfer pressure efficiently and maintain a reliable vacuum seal, helping the brake system respond predictably under normal driving and sudden stops. Each booster is subjected to end-of-line testing with proprietary equipment to verify function before it leaves the factory.

This part cross-references Hyundai/Kia OE numbers 59110D9200 and 591102S000 for the same application. It is a practical replacement choice for Kia Sportage and Hyundai Tucson models that require a booster without an attached master cylinder. The B3515 part number should be matched to the original unit and brake system configuration before installation.

What It Helps Address

• Hard brake pedal feel
• Reduced braking assist from a failing vacuum booster
• Inconsistent pedal response during braking
• Vacuum seal loss in the booster assembly
• Brake system performance issues tied to booster wear

Installation Notes

Verify master cylinder stud thread size, mounting layout, and brake system configuration before installation. This booster does not include a master cylinder, gasket or seal, front seal, brake pedal rod extension, or mounting bracket. Confirm fitment against the original part number B3515 and the vehicle application before service.

Quality Assurance

MPA Electrical subjects each unit to 100% end-of-line testing using proprietary testing equipment. The remanufactured construction and treated replacement components are used to support vacuum sealing and pressure transfer consistency.
