2023-2025 BMW Rear Brake Click Noise TSB SIB 34 07 25

Owners of certain 2023-2025 BMW models may notice a distinct "loud 'click'- type noise" emanating from the rear axle brakes. This noise typically occurs when the vehicle begins to move, either forwards or in reverse. This specific concern, often referred to as a BMW i5 rear brake click, is detailed in BMW Service Information Bulletin (SIB) 34 07 25, which provides a correction procedure for technicians.

Symptoms of the Rear Brake Click

The primary symptom is a noticeable and often repeatable "loud 'click'- type noise" from the rear wheels. This sound is most apparent when the vehicle starts moving from a standstill, whether accelerating forward or reversing. Owners might hear this BMW i5 rear brake click during routine driving, indicating an interaction within the brake assembly.

Cause of the BMW i5 Rear Brake Click

BMW has identified the root cause of the "loud 'click'- type noise" as the interaction between the spring clips and the brake caliper carriers on the rear axle. Over time, this interaction can lead to the audible clicking sound as the vehicle's brakes engage or disengage during initial movement.

Repair Procedure Summary for SIB 34 07 25

The repair outlined in SIB 34 07 25 is straightforward and involves applying a specialized paste to specific areas of the rear brake calipers. The procedure is as follows:

1. Initial Review: Technicians must first check the VIN-specific Repair History (Claims) to ensure that a prior claim for this repair has not already been submitted and accepted.
2. Wheel Removal: The rear wheels of the vehicle are removed to gain access to the brake components.
3. Spring Clip Removal: The spring clips on both rear brake calipers are carefully removed.
4. Paste Application: An approved brake pad paste is applied. A small amount of this paste is precisely applied to the top and bottom surfaces of both rear caliper carriers. This paste helps to lubricate the contact points and prevent the clicking noise.
5. Spring Clip Reinstallation: The spring clips are then reinstalled onto the brake calipers.
6. Wheel Reinstallation: The rear wheels are mounted back onto the vehicle.
7. Noise Reassessment: Finally, the vehicle is tested to confirm that the "loud 'click'- type noise" complaint has been resolved.
