Detailed Description

MPA Electrical B3123 is a reman vacuum brake booster engineered for the 2005-2010 Honda Odyssey. It restores vacuum-assisted braking by transferring pedal input into braking assist with reduced pedal effort, which is important when the original booster shows loss of vacuum seal, hard pedal feel, or inconsistent assist. The metal housing and treated replacement components are used to support vacuum retention and stable pressure transfer in the brake system.

This part cross-references Honda OE number 01469SHJA00 for the same application. If you are replacing a worn Honda Odyssey brake booster, B3123 provides the correct vacuum booster format without a master cylinder. The part number B3123 should be verified against the vehicle’s original booster configuration before installation.

What It Helps Fix

• Hard brake pedal feel on a 2005-2010 Honda Odyssey
• Reduced vacuum assist during braking
• Brake booster vacuum seal leakage
• Uneven or delayed pedal response
• Booster-related braking performance loss

Installation Notes and Tips

Confirm the vehicle is a 2005-2010 Honda Odyssey and compare the original booster layout, mounting points, and master cylinder stud thread size before installation. This unit does not include the master cylinder, brake pedal rod extension, gasket, seal, or mounting bracket, so reuse or source those components as required by the vehicle setup. After installation, inspect vacuum connections and verify proper pedal feel and brake assist operation.
