Abstract:
1. A method for identifying a location of active corrosion in a metal brake component of a brake system through assessing a concentration of iron in brake fluid, comprising the steps of: (a) contacting a colorimetric reagent and a brake fluid sample located nearest to a first brake component at a first location in the brake system, wherein said colorimetric reagent reacts to produce a color indicating the presence of iron in said brake fluid sample, and (b) observing and comparing said color with a standard indicating an iron concentration of about 50 parts per million or greater, wherein if said color matches said standard indicating an iron level of about 50 parts per million or greater, additional testing of said first brake component at said first location in the brake system is performed in order to identify and confirm active corrosion of said first brake component.
