Breakline leak

No, that kind of leak is typically from the seal in the master cylinder. It drips out where the pushrod goes in and flows down into the small crevice in the "firewall". From there it flows into the tunnel. All of this is hidden so that's why you don't see any evidence.

Less likely is a leak where the reservoir hose connects to the top of the M/C. That can work its way thru the firewall.

If you replace the M/C, be sure to very carefully inspect the steel lines, especially where it passes under the pedal cluster.

If you don't know when they were replaced, I would change the rubber hoses to the wheel cyls; they could well be a qtr-century old!

Dunno Jim! I think you missed where Tim said "(right in front of the trany)". Sounds like a brakeline leak in the steel brakeline running to the rear of the car. I had one of those recently, luckily for me in the driver's side floor area! Sounds like Tim's leak is a lot farther back, making fixing it a lot more complicated/harder.

I'm stickin' by my diagnosis . The fluid from the M/C runs down the length of the tunnel and finally drips out at the drain hole, which is just forward of the tranny. And that's why he could see the fluid in the tunnel thru the inspection plate opening.

I don't think there's any way that a leak in one of the back lines could get inside the tunnel.

Hope we hear from Tim soon... LOL Jim
