Overview

Wagner Brake QuickStop ZD1839 is a disc brake pad set built for rear brake service on select Cadillac applications. It uses a ceramic friction material and includes features aimed at consistent braking feel and reduced noise-related vibration.

Fits 2016-2017 Cadillac ATS, rear, except performance brakes; fits 2019 Cadillac ATS, rear, except V Series and except performance lining; fits 2019 Cadillac CTS, rear, except Brembo caliper.

Key Features

• Ceramic friction material for stable everyday braking characteristics.
• Slotted pad design to help manage heat and surface debris.
• Chamfered edges to support quieter operation.
• Pad shims included for noise control.
• Mechanical pad wear sensor included.
• Abutment clips included.
• FMSI 8886-D1839 for application matching.

Product Details

QuickStop ZD1839 is part of Wagner Brakes QuickStop line, which focuses on restoring like-new braking performance with pad construction tested for consistent friction over the service life. The 100% post-cure process is used to promote even friction behavior, while the pad design is engineered to reduce vibration that can contribute to brake noise. For Cadillac ATS and Cadillac CTS rear brake service, ZD1839 provides a fitment-specific replacement option that aligns with OE-equipped ceramic pad applications.

This part cross-references Monroe Shocks & Struts (e.g., 23275448, GX1839) for the same application.

Common Issues This Part Can Address

• Brake noise caused by vibration at the pad interface.
• Uneven braking feel from worn friction material.
• Reduced stopping performance from pads at end of service life.
• Fitment mismatch on rear ceramic-pad applications.
• Service concerns related to worn wear sensor components.

Installation Notes

Verify caliper style and OE brake package before ordering. This pad set is listed for rear applications only and excludes the noted performance and Brembo configurations. Confirm rotor condition, pad hardware condition, and sensor routing during brake service.

Quality Assurance

Wagner Brake tests QuickStop pads to restore like-new performance and uses a post-cure process to help maintain even friction output throughout pad life.
