After just replacing my 77 FJ40's MC, I was thinking about how every time I opened the reservoirs(esp the rear-which was leaking and the reason for the replacement), that the little metal baffle in the cap was always rusted badly. I tried lots of fixes to try and keep this little thing clean--no one made a stainless one, so I just tried oil/Nox-Rust/silicone/etc. nothing worked. I had a feeling this thing was just being subjected to moisture from the natural "breathing" of the system--contributing to rust forming in the steel brake lines and messing with the MC.
Here's an idea I came up with to combat this--
Remove the little baffle that's in the cap(s). Poke a 1/8" stainless tube into the cap vent hole. Hook this tube up to some common fuel line(used for weedeaters and chainsaws). Pipe this to a small canister(I used leftover shampoo and body lotion bottles from a Hotel in Cody, Wy.) Fill the little canister with indicator Silicon Desiccant. This will be bright blue when dry, when it gets saturated with moisture, it turns pink.
When the dryer gel gets loaded with moisture, simply replace it with fresh. Put the depleted gel into an old hair curling iron heater and dry it back out. Store in an airtight container til you need it again--note: the gel must not be subjected to temperatures higher than 180 deg F, or it will be rendered unusable.
I do not know if this fix will work perfectly, as the system may need an atmospheric vent(as it was designed)----in that case, it would be an easy thing to poke a small(<1/64th) hole in the gel canister to accommodate.
