This is the Performa washer...brake noise is perfectly normal when this unit stops. The machine must have all 4 rubber pads on the feet or it will slide. If the pads are in place and not worn, Maytag recommends No-Slip discs
under the feet to keep it in one spot, especially on slick floors.
You could stop the brake squeal (if you had the $100 brake tool) with a simple sanding of the stator to break the glaze that forms after years of stopping.
