Product Details

The Power Stop Z16 Low-Dust Ceramic Brake Pads line is focused on everyday replacement braking with a cleaner wheel appearance and reduced noise. For Cadillac ATS and Cadillac CTS rear brake service, part number 16-1839 provides a ceramic pad option that follows OE-style fitment and construction practices while using a thermal scorched surface to help shorten the initial bedding period. This part cross-references Wagner Brake ZD1839 for the same application.

Common Brake Issues Addressed

• Excess brake dust on rear wheels
• Squealing or noisy brake operation
• Uneven pad wear
• Longer-than-desired break-in after pad replacement
• Reduced braking consistency from worn rear pads

Installation Notes and Tips

Confirm rear fitment by year, model, and package configuration before installation. Inspect rotors, caliper hardware, and wear sensors during service, and replace any worn components as needed. Follow the vehicle manufacturer’s bedding procedure after installation to help the pads seat properly. Part number 16-1839 is intended for rear brake service on the listed Cadillac applications only.

Power Stop designs the Z16 Evolution line as an OE-style ceramic brake pad replacement with emphasis on consistent wear, low dust, and reduced noise. The included shims and wear sensor support a complete rear brake service on the confirmed ATS and CTS applications.
