Low Frequency Moan Noise Heard During First Brake Apply
This bulletin involves installing an anti-vibration bracket to the rear brake caliper.
A low frequency moan noise is heard during the first brake apply when in reverse, while
the vehicle is cold or has been parked for several hours.
An audio sound file of the moan noise can be found in DealerCONNECT> TechCONNECT
under: Service Info> 05 - Brakes> 05 - Brakes, Base> Diagnosis and Testing.
If the low frequency moan noise can be verified, the addition of the anti-vibration bracket
may correct the condition.
