Brake fluid, tunnel, and rust.

[75Flamebug]

I've got kind of a dumb question. Will brake fluid in the tunnel cause rust in there?

Unless things changed after 69. Your rear brake line should run outside of the tunnel along the floor between the drivers seat and the tunnel. Are you sure it is brake fluid? Maybe tranny fluid leaking from your nose cone bushing/seal.
Good Luck.

even if brake line runs outside of the tunnel it's still possible to have brake fluid in there if the leak comes from the MC where it mounts to the napoleon's hat.

I'm pretty positive that its break fluid. I had it sitting in the shop and pumped the breaks and let sit for quite a while with no puddles outside of the tunnel. My reservoir runs dry all the time. Its gotta be break fluid. Well, I don't think I have brake lines outside of the tunnel because I can see a line when I lift up the hatch under the back seat. I'm almost positive that its a brake line, but I'll have to check. To be honest, I really don't have the cash to replace the MC unless I have to. hahaha. I'm just worried about the tunnel. I don't want to have tunnel rust, cuz I wouldn't know what to do. I just bought this car last year as my first car, sooo....

Yep that's the brakes er breaks. Who needs breaks anyway I mean brakes. I think I'll take a coffee brake er break yay that's the ticket

[75Flamebug]

I'm starting to get pretty confused, especially with all of the pictures on the internet. I'mma have to find a repair manual and find out where the brake lines are even suppose to be. :/ ugh...

A leaking master cylinder can dump fluid inside the forward bulkhead (napoleon hat), which then goes into the tunnel. You can wash it out with a water hose. Jack up the front of the car a couple of inches and the water (and brake fluid) will drain out the drain hole in the rear. Just let the tunnel dry out before you put the access covers back on.

That leaking master cylinder will eventually fail. Press the pedal and no brakes. Replace the master ... you can't afford not to.

Brake fluid strips the paint off metal if not washed off quickly with water. So the brake fluid itself may not cause rust but once the paint has been removed it will rust from the moisture in the air.

In the attached link. You can see the routing of the brake line snaking around the accelerator pedal. It then runs outside of the tunnel to the rear "T" fitting.
Someone please educate me as to how the brake fluid can get into the tunnel. Not just it can. But how it gets there. Is there a weep hole in the napoleon hat? I don't get it.
Thanks in advance.
BTW The link is an image from an SB.

Park your bug then, the MC is leaking and the time is past to replace it, money or no money. If you crash because of no brakes you won't have to worry about tunnel rust
67, the firewall is two pieces and when the MC is leaking it ends up in the tunnel.

Its not that I don't have the money, but I need the money for college and college necessities. I don't want to waste money on something that won't fix it.

Just to be clear here. I am not trying to be difficult. Just trying to learn. In the image below it appears that the napoleon hat bottom side has a void that allows escaped fluid to enter the tunnel. Is this correct? This image is looking from the bottom of the hat.

Thanks all.

this pic from the gallery shows the bottom plate of a super:

see the ridge across the tunnel just below the napoleon's hat?

here on a standard (pic from the gallery):

this allows air to circulate between the napoleon's hat inner cavity and the tunnel.

I believe they got dunked into a tank of rust preventative, but there is no way to paint inside once it is put together.
