Driving at any speed when applying light to medium brake pedal (as if slowing to exit interstate highway) brakes begin to pulse. It feels as if its in the rear brake. Taken to dealer several times. They have replaced the shoes and drums twice. It lasts 2k miles and starts all over.
The contact owns a 2010 GMC Sierra hybrid (na). The contact stated that the brakes grabbed when the vehicle was coming to a stop, which made the vehicle come to an abrupt jerking stop. The contact also stated that when slowing down from higher speeds, he had to depress the brake pedal with extreme force. The dealer gave the contact a memo from the manufacturer to pump the brakes on the hybrids for a smoother stop. The failure mileage was 15 and the current mileage was approximately 2,000.
