Found corrosion on the brake lines and master cylinder, and other lines that are located under the battery corrosion plate. The battery corrosion plate was a good idea. However, putting brake lines & other components under were are not a good design. It's flawed, for if the battery plate becomes corroded, then it leaks onto the lines below and causes damage as in my vehicle.
