Rust Rust Rust in master cylinder

After drowning the engine in vinegar I decided to take a peek in the m.c. WHEW!!!! talk about corrosion and rust. Although the car sat for days under water I thought the brake system was air tight? What now? I've been told everything from replacing every line and hose to flushing with all sorts of fluids.

Any suggestions would be appreciated.
Thanx :beer

 

the lines, calipers and wheel cylinders should be alright..... but I'd replace or rebuild the master cylinder and flush the lines out....actually the lines are sealed and should be alright.....give it a try :bglasses:

 

Thanks Mark. Should the m.c. be sealed from just this?

 

well It should.. but ..water has it's way of finding it's way in.. :Smarty:

 

Rust in MC

If you flush the system, and replace the master cylinder - consider using DOT 5 (Silicone) brake fluid - it does not absorb moisture, and works great in vehicles that are stored for long periods, (You may have to replace the wheel cylinders also). I used DOT 5 in my Riv, after the entire brake system was redone, and the fluid is crystal clear after 5 years, and shows no signs of rust in the system.
Just make sure you check the fluid level every season.
Another advantage of silicone fluid is it won't damage painted surfaces. :TU:
