1991 200qt Avant. Ok so I'm getting a squealing sound from what sounds like my front brakes. Only when moving and below 40 mph. I have the 2bennett 4piston Brembos in the front. Also more prevolent when turning the wheel. Just rebuilt my rear brakes. Checked all my fluid levels. All ok. None of the caliper are hot indicating they are not frozen. If I put my brakes on the squeal goes away? Good pads and rotors in front. Pressure bleed my brakes twice. Thought it was gonna be the master cylinder. But none of my brakes are locking up? Any thoughts? I'm a bit stumped. And I did a search didn't find any resolutions.
