I bought an '88 Brougham several months ago and have been gradually performing preventive maintenance just to get a starting point as the previous owner did not keep any records.

Today I got around to thoroughly checking the braking system.
Results of my inspection are as follows:

Rear auto/adjusters frozen. Did not realize that they are automaticly adjusted only when the E-brake is applied. Apparently the previous owner never used it.

Replaced front pads, pins etc. had some life left on the pads but changed out everything using AC/Delco OEM replacement parts.

Evacuated old brake fluid. Went to a shop for this as I do not own an automatic bleeder. Wow, what crap came out of the system! Brake fluid looked like auto trans fluid. Pumped a gallon and a half of fresh fluid through the system after cleaning the resevoir. Cost: $40.00 to do this but I feel a lot better knowing what I have now.

Just wanted to pass the fluid tip on to others.

That's something I've been planning to get done. My '79 still has the original fluid. The car has low mileage, but that fluid is still 28+ years old.
