Detailed Description

Wagner Brake ZD2189 is a QuickStop disc brake pad set developed for rear brake service on select Buick Envision and Cadillac XT4 models. The ceramic friction compound, slotted surface, and chamfered edges work together to support smooth, quiet braking under everyday driving conditions. The integrally molded friction attachment and included shims add to the pad’s refined fit and finish, while the stainless-steel hardware supports a complete brake job. If you are replacing worn rear pads on a Buick Envision or Cadillac XT4, ZD2189 provides a direct service solution for the specified applications.

This part cross-references Raybestos Brakes (e.g., EHT2189H) for the same application.

What It Helps Address

• Squealing or vibration during braking
• Reduced stopping performance from worn rear pads
• Uneven pad contact caused by aged friction material
• Brake noise related to pad resonance
• Service needs on rear brake pad replacement intervals

Installation Notes

Verify fitment by year, make, model, position, and notes before installation. This part is listed for rear applications only, with QuickStop-specific notes on certain Buick Envision coverage. Inspect rotors, caliper condition, and pad contact surfaces during service to support proper brake operation.

Quality Assurance

Wagner QS brake pads are designed and tested to restore like-new performance. The QuickStop line uses noise-control features such as multi-layer shims to help reduce vibration and promote quieter stops.
