Reoccurring pulsation complaints are perhaps the second most common reason a customer returns after having brake service. The brakes operate normally for the first 3,000 to 6,000 miles, but then the customer notices a high-speed pulsation when getting off the exit ramp on his way to work one morning. The customer returns to the shop with the pulsation complaint and leaves with usually one of two “fixes” – the rotors being machined or replaced. The usual explanation given the customer is that the rotors “warped.”
