I hit the brakes and the pedal went to the floor. Luckily, I was going up an exit ramp. I pumped the pedal several times and stopped OK. The brake light on the dash came on and stayed on. It's still on.

I checked the brake fluid and both reservoirs were full.

Do you think it is the master cylinder?

Could it be the proportional valve is stuck?

What else could it be?

If both reservoirs are full, the problem pretty much has to be the master cyl. Either that, or your rotors are warped, and driving to/from the Gathering has pumped the system full of air.
I would suggest first trying to bleed the system, drive it a few miles, and see if that helps. If not, then the suggestion would be to replace the master....Ouch

Sorry, I should have mentioned that I am home safe and sound.

Would it go to the floor all of a sudden if one rotor was warped?
I haddened driven it since last fall, but the brakes were checked before I left and they were normal for about 1400 miles. Of course, most of that was interstate driving, with not much stopping.
They seemed normal until the pedal just went to the floor.

OMG Dave, you drove from WI to NY with little or no brakes??  I'm glad you made it home safely.

Oh man! That's makes for an interesting ride home doesn't it? Shocked

That same thing happened to us one year going to Adam's "Corvette for a Cure" doings. The seal in the master cylinder must have rolled causing it to leak internally. Then after pumping the brakes a few times it was fine the whole trip. But I went ahead and replaced the master cylinder and booster. 

Glad you made it home ok.

Fortunately, on interstate I didn't have to use the brakes too often. Just those darn toll booths.
I stopped twice to fill one tank and empty the other.
No close calls as the traffic was light and construction was minimum.

Glad you made it home. I lost mine on Friday, did lots of Nascar driving. Down shifting and what brakes I had. Hard to find a good MS, I had 3 in the last 5 years. Looked at all sites, just ordered from Zip Products a new MS. Try to stay away from remains, They don't last, junk.

Ouch  YUP!  I feel your pain. NO RE-MANS for me. Junque. Brakes need "NEW" stuff. No chances taken.

Glad you made it home safe Dave. That is one of the few parts I have not replaced, it will probably go out when I'm on a trip! Good to know the tip about staying away from the rebuilds.

Yes Dan, I went by Sheboygan, at about 6:30 a.m.

It really wasn't that bad. Just had to leave extra room in front of me.

Investigation found that the master cylinder was OK. Didn't loose any fluid. There was a stain on the front left tire that could be brake fluid.

There was air is the system. Front wheel bearings had some play in them, so maybe the rotors pumped air into the calipers. All wheels and master have been bleed, so now we keep an eye on the brake pedal.


Strange that the brakes were fine for 1600 miles and then suddenly they failed. No indication that they were getting spongey.

 Boy I hear ya. I had absolute confidence in anything on my vette cause I am the only one who touches it.....Then, my brake pedal went to the floor.........very unsettling indeed.
