I have often wondered what the answer is to the question of squealing. This Spring I removed very good woven lining from the rear brakes of my 40B and replaced it with molded lining with the ides that I might stop the loud squealing. The Roadster has low mileage and has excellent uncut steel drums all around. Even the roller tracks show no wear. The noise stopped. The fronts had earlier been replaced with molded lining. The question remains: why? Gar Williams
