Rear Brake Disc Corrosion Issue
The Land Rover Technical Bulletin LTBOO9IONAS1 addresses a rear brake disc corrosion issue affecting certain model years and VIN ranges of the Land Rover Discovery Sport and Range Rover Evoque.
Causes and Symptoms
The corrosion may be accompanied by a grinding noise and/or vibration/judder while braking. This issue is caused by the lower work rate of the rear brakes, which can prevent rear disc surface oxidation from being fully cleaned on brake application.
Service Instruction
The service instruction includes steps to inspect and replace the rear brake pads, caliper carrier, and brake discs. The procedure requires the use of specific tools and software, and includes warnings and safety precautions.
