Wagner Brake ZD946 Disc Brake Pad Set - Front

Overview

Wagner Brake QuickStop ZD946 is a ceramic disc brake pad set built to restore like-new braking performance. It uses a 100% post-cure process for consistent friction behavior and is engineered to reduce vibration-related noise.

Fits BMW X3, front; BMW Z4, front; BMW 330Ci, front; BMW 330i, front; and BMW 330xi, front. This part cross-references Centric Parts 301.09460 for the same application.

Key Features

• Ceramic friction material for stable braking characteristics.
• Slotted pad design to support cleaner pad operation.
• Chamfered edges help reduce noise and promote smoother contact.
• Included shims and abutment clips support a complete pad service.
• FMSI 7592A-D946 identification for catalog matching.

Detailed Description

The Wagner Brake QuickStop ZD946 is engineered for BMW front brake service where consistent pedal feel and low-noise operation matter. The ceramic formulation, slotted design, and chamfered edges work together to support even friction delivery, while the post-cure process helps maintain performance across the pad’s service life. The ZD946 is a direct-fit option for BMW X3, BMW Z4, BMW 330Ci, BMW 330i, and BMW 330xi front brake applications listed in the fitment data.

QuickStop is Wagner Brake’s pad line focused on restoring original braking behavior with application-specific engineering. The ZD946 part number is also referenced as 301.09460 through Centric Parts and cross-references 34116761243, 34116779652, DX946, DX946W, and FX946.

What It Helps Solve

• Brake noise caused by vibration at the pad interface.
• Uneven friction performance during pad wear.
• Reduced braking response from worn front pads.
• Service issues tied to missing shims or abutment clips.

Installation Notes

Verify the vehicle’s front brake application against the fitment data before ordering. Inspect rotors, caliper hardware, and pad contact surfaces during service, and follow the vehicle manufacturer’s brake procedure for bedding and torque specifications. Fitment notes indicate pending obsolescence and reference ZX946 for some applications.

Quality Assurance

Wagner Brake states that QuickStop pads are designed and tested to restore like-new performance. The 100% post-cure process is used to promote even friction behavior throughout the pad’s service life.
