Detailed Product Description

The MPA Electrical B3364 power brake booster features a metal housing that ensures structural integrity and long-term durability. Its vacuum booster design uses engine vacuum to amplify the force applied to the brake pedal, reducing driver effort and improving braking response. The diaphragm diameter measures 10.74 inches (272.8 mm), which is critical for proper vacuum assist performance. This unit includes two mounting studs and is compatible with master cylinders that have an 8 x 1.25 mm stud thread size. Note that this booster does not come with a master cylinder, brake pedal rod extension, gaskets, seals, or mounting brackets, so these components must be sourced separately if needed.

Common Applications and Issues Addressed

• Restores brake pedal assist in Nissan Versa vehicles with failing or weak power brake boosters
• Eliminates hard brake pedal issues caused by vacuum booster failure
• Resolves inconsistent brake pedal feel due to diaphragm wear or leaks

Installation Notes and Tips

When installing the MPA Electrical B3364 power brake booster on a Nissan Versa, ensure the master cylinder is compatible with the 8 x 1.25 mm stud thread size. Since this unit does not include mounting brackets, gaskets, or seals, verify that these components are available and in good condition before installation. Properly torque mounting studs to manufacturer specifications and check for vacuum leaks after installation. It is recommended to bleed the brake system following booster replacement to maintain optimal brake performance.
