SERVICE INFORMATION

If a 1996 to 1999 I30 vehicle exhibits a groan or humming noise from the rear of the vehicle after releasing the brake pedal and moving forward slowly at approximately 5 mph (8 kph), use the procedures in this bulletin to repair it.

The incident is intermittent and may be duplicated by releasing the brake pedal while the vehicle is stopped and then moving forward at approximately 5 mph (8 kph).

This incident can be caused by a slight tension on the parking brake cable resulting in the brake pads not withdrawing completely from the surface of the rotors after release of the brake pedal. This contact results in a low frequency groan or humming noise.

SERVICE PROCEDURE

1. Verify that the noise identified by the customer is from the rear brakes and occurs under the conditions described above,

2. If the noise occurs as above, replace the parking brake cables and rear pad retainers with the parts listed in the Parts Information table.

3. Check and readjust the parking brake cable in accordance with the Brake System (BR) Section, PARKING BRAKE CONTROL - Adjustment, of the Service Manual.
