GLS63 2017 Rear Brake Squeal Mystery: Help Needed!
I'm experiencing a perplexing issue with my 2017 GLS63's rear brakes, and I'm hoping someone here might have encountered something similar or has some insights to share.
Here's the rundown:
1. The squeal comes and goes unpredictably.
2. It primarily occurs when applying soft brake pressure, especially over humps or when coming to a complete stop.
3. Interestingly, there's no squeal when applying hard brake pressure.
4. The noise seems to manifest only after about 10 minutes of driving; it's absent when the brakes are cold.
We've already tried replacing both the rotors and pads for the front and rear brakes, yet the issue persists, with the most prominent noise originating from the right rear wheel.
Any suggestions or experiences you can share would be greatly appreciated! Thanks in advance for your help."
