Toyota—Lexus G300, IS250, RX330 and Toyota Kluger—Brake Master Cylinder
What are the defects?
During vehicle assembly, Toyota brake fluid contains polymers that act as a lubricant for certain brake system components. If the replacement brake fluid used has insufficient polymers, the brake master cylinder rear rubber seal may become dry and curl during brake application.
What are the hazards?
If the defect occurs, a small amount of brake fluid could leak from the rear of the brake master cylinder resulting in a low brake fluid level and illumination of the brake warning light. If the vehicle is operated in this condition, the brake pedal feel could change, and eventually braking performance could begin to gradually degrade.
What should consumers do?
All owners of affected vehicles will receive a Recall Notification Letter.
Owners are advised to contact their authorised Toyota Dealership for inspection and replacement of the rear rubber cup of the brake master cylinder.
