When I take my foot off the brake, there is a squeal or whistle. It’s sporadic and sometimes loud and long, other time low and short. It doesn’t seem to happen when the mechanic is driving. And they can’t determine cause.

**_JLC, More Information Is Requested.

**Your description of the symptom is very good.**

However, it will save lots of suggestions and guesses if you could elaborate a bit on what has been done to diagnose the problem besides the roadtest by a mechanic.

Have all 4 wheels been removed for a thorough inspection of brake parts, for instance ?

Can you tell if the noise is coming from the dash board area, a wheel, right or left, front or rear ?
