Detailed Description

Wagner Brake QuickStop ZD1903 is a ceramic disc brake pad set engineered for front axle applications on the Mazda MX-5 Miata and Fiat 124 Spider. The pad design uses slotted faces, chamfered edges, and included shims to support quieter operation, while the post-cure process helps maintain consistent friction characteristics over time. This part cross-references Centric Parts 301.19030 for the same application.

• Uneven friction feel as pads wear through normal use.
• Reduced braking consistency from worn or glazed pads.
• Need for a front brake pad replacement on supported Mazda and Fiat applications.
• Wear monitoring needs with a mechanical pad wear sensor.

Installation Notes

Verify brake system configuration before ordering, especially on Fiat 124 Spider and Mazda MX-5 Miata applications with Brembo brakes. Fitment notes also identify applications that include pad installation hardware. Confirm the FMSI 9130-D1903 reference and part number ZD1903 against the vehicle’s brake setup before installation.

Quality Assurance

Wagner Brake QuickStop pads are developed and tested to restore like-new performance. The brand’s post-cure process is used to promote even friction behavior throughout pad life and to support quieter operation.
