No brakes!, Brake pedal went to the floor Options

[mburkhart]

So I was out for a cruise around the neighborhood the other day and things were going great until the brake pedal went to the floor. I was able to pump it a few times and restore pressure and crawled home in a low gear. Each time I used the brakes the pedal would go to the floor until I pumped it a few times. Scary!

Once home I looked under the car and inspected the soft lines at each caliper but they looked fine and no leaks. The brake fluid reservoir is still full. I'm not sure where the problem is.

What should I be looking for?

Check me on this - the only difference between regular and easy is how the lines from the reservoir fit/are located into the master cylinder, correct?

The regular version requires you to push the hard lines into the rubber grommets, right?

Yes.

I asked Bob Russo how he does it. He was the crew chief for the Holbert 962 race team among other Porsche experiences. He said he wrestles them in. There is no real trick. I was told it's way easier to assemble the MC to the lines on a bench and then feed everything up from the bottom. Fuel tank has to come out but sometimes that would be easier.

that certainly would make it easier, both having the tank out and bench installing the lines. This was one of the first jobs i did on my 914 after purchasing it. First time i left the washer out and found out the hard way it was necessary, but once done correctly , was leak free about 8 years. The next failure was back last winter right before going to Amelia island, puddle on the floor inside under the pedal cluster. remembering my previous experience i ordered the new 19mm easy install one from 914 rubber.
being i have no lift and therefore limited space under the car, it was still very difficult to attach the lines and tighten the clamps.
If i had to do it again(Lord i hope not ever!) i would do exactly like Mark and Bob Russo suggest if you can, and do that part on the bench. .

Let us know how your experience goes.

When I did mine I installed on a bench, just the lines not the reservoir, then connected the rest up top. It was really pretty straightforward but I forget if I had the tank in or not.

grommets on the line first, then push the line/grommet assembly into place after verifying the washer is there.
