We have recently checked several cases where a "crunching" noise occurs when brakes are applied at low car speeds. Although this noise can be caused by several points of movement in the 1950 Buick brake assembly, it appears that a major portion originates between the 1950 Buick brake shoe hold-down spring retainers and the brake shoe [...]
