BACKGROUND
Certain 2004 Model Year Lexus RX 330 vehicles may exhibit a hard brake pedal feeling during cold starts that may cause the brake warning light
to illuminate. This condition is caused by a vacuum leak, and is due to inadequate sealing of portions of the brake booster diaphragm as it moves
within the brake booster housing.
