Weird brake problem- '85 325e
 

The brake light came on (1985 325e) so I checked the fluid and it was at the
min mark. I kept adding fluid but it wouldn't come up any higher. I look
inside the car and there is all the fluid in a puddle on the floor mat.
I notice there is somekind of overflow? or pressure relief hose that runs
from the reservoir thru the firewall right into the car. It appears as if
the fluid is running right out of that tube. Is there supposed to be some
kind of check valve in the reservoir to prevent the fluid from running right
out of that tube? Any info on this problem would be greatly appreciated.
I'm hoping maybe I just need to replace the reservoir.
Thanks,
Mike

Well I did a little research....the hose is supposed to go to the clutch
cylinder...duh... seems that a spring located just above the clutch
cylinder came out of its bracket and pushed the hose off it's fitting.
Maybe cheaper to fix than I thought.

thanks
mike

If the fluid was at the min mark I don't think the light would trip. I'd
be more suspicious of a master cylinder failure or worn out break pads.
Have you checked the pads?

And no, there's no overflow hose that leads into the interior of the car.
I can't picture the engine bay of an E30 in my mind and can't remember if
the master cylinder is in the bay or inside of the firewall. But, I think
it is in the engine bay. I think the clutch master cylinder is in the
passenger compartment. Maybe the return hose from the clutch has a fault.
But even so it seems you'd have already known about that...
