2022-2026 Jeep Wrangler Disc Brake Caliper Inspection

Mopar has issued a Quality Inspection Request (QIR) concerning disc brake calipers for certain 2022-2026 Jeep Wrangler vehicles. This communication, identified by NHTSA ID 11028889, directs dealerships to inspect their inventory of a specific caliper assembly part to ensure only correct components are used for sales and service.

The primary concern is the proper orientation of the bleeder screw on the disc brake caliper. Incorrectly oriented bleeder screws can impact the effectiveness of brake bleeding procedures, which are crucial for maintaining optimal braking performance and safety. This Jeep Wrangler disc brake caliper inspection is a proactive measure to prevent potential issues before they arise.

What's the Issue?

The Quality Inspection Request focuses on disc brake caliper assembly part number 1BP01077AA. Mopar has identified that some of these parts may have been manufactured with the bleeder screw in an incorrect position. While the document does not detail specific failure modes, the correct functioning of brake components is paramount for vehicle safety.

Dealers have been advised that they may have stock of these parts either on hand or in transit. The purpose of this communication is to ensure that any suspect parts are identified, quarantined, and returned to prevent their use in new vehicle sales or service repairs.

Identifying Suspect Calipers

Identifying the suspect disc brake calipers is a straightforward visual inspection. The key differentiator is the location of the bleeder screw on the caliper assembly. This Jeep Wrangler disc brake caliper inspection relies on a clear visual cue:

• Good Parts: Calipers with the bleeder screw located on the Right hand side are considered correct and can be used for sales and service.
• Suspect Parts: Calipers with the bleeder screw located on the Left hand side are deemed suspect and must be quarantined immediately. These parts are not to be used.

This distinction is critical for ensuring that only properly manufactured and functioning brake components are installed on vehicles.

Action Required for Dealers

Dealerships that have been identified as potentially having stock of the affected part number 1BP01077AA are required to take specific actions. This includes thoroughly checking all existing inventory and any incoming shipments for the suspect calipers. The goal is to remove all incorrectly manufactured parts from the supply chain.

Any suspect parts identified during the Jeep Wrangler disc brake caliper inspection must be returned to the facing depot. The specific instruction is to use Return Code 02 for these returns. Dealers are also advised to return any open orders in process for this part number. For replacement parts, new orders must be placed.

Important Dates and Contact Information

This Quality Inspection Request was published on February 11, 2026, and dealers are instructed to complete the return of all suspect parts by March 4, 2026. This deadline is crucial for ensuring the timely removal of non-conforming parts from circulation.

For any questions regarding the return process or other aspects of this communication, dealers are directed to contact Mopar via email at [email protected].
