Four problems related to brake hoses, lines/piping, and fittings have been reported for the 1999 Buick Century. The most recently reported issues are listed below.
Was driving with my 2 young boys, needed to stop and the brakes became very spongey. Pulled vehicle over and noticed brake fluid coming from the rear of the vehicle. Upon further investigation found a brake line rusted through.
Brake failure, front brake line corrosion (rust through) resulting in complete loss of brake fluid. Thankfully no accident resulted. Correction required new brake line replacement and replacement of lost fluid, etc this failure is the same type which occurred to our 2000 Buick Century. In that car first the front brake line failed (like the 1999 did), and about a year later the rear brake line failed with the same corrosion problem. The incident happened out of state and the repair shop manager stated "this has become a common problem and that he has replaced many failed brake lines.
Brake lines on 1999 Buick Century rusted out, resulting in complete loss of braking. Brake lines are severely rusted in most locations in the rear of the car. Fuel filler line is heavily rusted, as of yet there is no leaking from this defect. Location on long island new york is not a heavily salted area.
Anti lock braking system heats up, the brake line heats and melts, causing the no fluid to braking system. Brakes are now damaged to point of total replacement at a cost of approx. $1,000. 00.
