Default Long term maintenance question

I bought a new 95 Corvette in 1995. I now have 24,000 miles on it. I have done all the scheduled maintenance as suggested in the manual. The manual does not mention ever replacing the brake fluid, clutch fluid, manual transmission fluid, power steering fluid, rear axle fluid. I intend on owning this car for many more years. Do these fluids last indefinately? I have owned other cars that recommend periodically changing some of these fluids.

I bought my 94 new. It now has less than 24k miles, and I've replaced all of the fluids at least once.

Thats one of my biggest complaints about the service intervals.
Brake fluid - change it every 2 years, its cheap less than $10 for the fluid.
I'll probably do the same with the trans, diff and clutch fluid.

And add to that the coolant. It's protective properties wear out. I'd also recommend that if you still have the Dexcool in it, to lose that and replace it with conventional ethylene-glycol antifreeze mixed 50-50 with distilled water. Also add a pint of Pencool 3000.

Get that brake/clutch fluid out of there ASAP. You've got a lot of water in the lines and that causes corrosion. New brake fluid every 2-3 years on a street car.

The other things - gear oils, break down with usage not time, so check the condition. Myself I'd change them every 4-5 years anyway, but based on your mileage I'm sure they don't _need_ to be changed.

I was told to replace the brake fluid every year (maybe overkill). But if you install a set of speedbleeders, it's a very fast and easy thing to do.

Brake fluid becomes contaminated very quickly by it's nature. You really can't change it too much. Maintaining clean fluid in a system will not only keep performance at it's maximum but also reduces hydraulic problems to virtually nil. Even in a clean and sealed system, brake fluid absorbs moisture over time. This leads to reduced performance and also to corrosion and the problems that it brings with it. Sticking of pistons, deterioration of rubber parts and etc.
