squeal stops/reduced 850

Hi all,

My 850 used to squeal like a freight train on every brake, but not anymore. I still hear it squeal once in a while but not as loud as it used to be.

The squeal stopped/reduced after I replaced the front flexible brake fluid line. The line was worn at both ends and I guess it expanded when pressure applied. My theory is that rear brake which was the source of the squeal uses two pistons to press the brake pads, and the expanded line reduced the pressure especially when the pressure on both pistons is unequal.

Anyway, I might be wrong but the squeal has gone/reduced..
