Detailed Description

MPA Electrical B1034 is a remanufactured vacuum brake booster engineered for direct replacement in select Dodge Ram trucks. It is designed for 1998-1999 Dodge Ram 1500, 1998-1999 Dodge Ram 2500, and 1998 Dodge Ram 3500, plus 1999 Dodge Ramcharger applications. The dual-diaphragm vacuum design helps deliver braking assist with reduced pedal effort, while the metal housing and treated internal components support consistent vacuum sealing and pressure transfer.

This part cross-references 4882866 and 5003326AA for the same application. Use B1034 when replacing a worn booster on a Dodge Ram 1500, Ram 2500, or Ram 3500 brake system that uses a vacuum booster without a master cylinder.

What It Helps Fix

• Hard brake pedal feel
• Reduced brake assist from a failing vacuum booster
• Inconsistent pedal response during braking
• Vacuum leakage at the booster assembly
• Brake assist loss caused by worn internal diaphragm components

Installation Notes and Tips

Confirm the vehicle uses a vacuum booster setup and verify master cylinder and mounting dimensions before installation. This B1034 booster includes the mounting bracket, but it does not include the master cylinder, brake pedal rod extension, gasket, front seal, or master cylinder seal components. Always inspect vacuum supply, check the brake pedal linkage, and bleed the brake system as required after service.
