One problem related to brake fluid leak has been reported for the 1997 Oldsmobile Aurora. The most recently reported issues are listed below.
Both rear brake lines are so extremely corroded it actually rusted through the metal brake lines in several different locations on both rear brake lines and is leaking in large amounts at the severe corroded spots of the lines. Also the front brake lines are also extremely corroded they just have yet to corrode completely through the metal line and leak brake fluid yet but can gurantee they will in less than 20k miles easily! and the master cylinder is not divided into 2 divided and separate resivoirs for the front and rear distribution braking hydraulic power in case the rear brake pressure would not be enough for the rear calipers to work or if the opposite happened to the front and its because fluid started leaking: that way there is still fluid left in the master cylinder resivoir for either the front brakes or rear brakes, whichever line(s) aaren't leaking and so the remaining braking axle still has remaining excess brake fluid to stop. ,.
