Brake Fluid: Testing and Inspection
NOTE: Swollen rubber parts indicate the presence of petroleum in the brake fluid.
To confirm that contamination exists, make the following test:
Place a small amount of the drained brake fluid into a small clear glass bottle.
Separation of the fluid into distinct layers will indicate mineral oil content.
If there is any question of mineral oil content, drain system, flush thoroughly and replace all rubber parts.
