Default Brake Pressure bleeding woes

Hi all,

So I decided to give my brake system a complete flush. Connected my trusty Motive pressure bleeder to the reservoir, pumped it up to a safe 10 psi, got through one rear caliper, all is well. Suddenly, I noticed brake fluid gushing out from under the front of the car. I immediately went to relieve pressure from the bleeder, but all pressure is already lost.

So what did I break/pop? I looked in the pedal box area, it's dry there. So it must be something under the car. How do I access the area to check?

Thanks in advance.

There is an overflow tube leading from master cylinder to a point behind the driver's side front wheel. You need to pinch off that tube before pressurizing the MC. By the way, you're not the first (or last) one to do dump brake fluid this way.

Porsche offers a little kit that eliminates this potential issue. It includes a new reservoir cap, a small rubber cap for where the overflow hose connects, and a small hose clamp. One of the first things I did to my 6/94 build date '95 993.

Thanks for the replies guys. Andreas, do you have a part # for this kit?

This is the line we are talking about right?
