Default brake locking up

I bought a 2006 base corvette in like new condition with less than 25,000 miles.
I have had the car for about 14 months I have put about 6000 miles on it. a few months ago backing out of the garage the brakes locked up.
I shut the car off and restarted it and no lock up? later that day it happened again slowing down for a light. same thing turned the car off and the brakes unlocked. about two weeks later happened again same thing. did that couple more times in the next couple of months. 5 months later it happened to me again last week. and again everything is working. Strange thing I'm not getting any codes or engine light.
All though before it happened last week i did notice the traction control symbol came up, and then it said it the active handling was recalibrating ? haven't had an issue since
Any Ideas?
Thanks
Tim

If the brake fluid is 10 years old I would bleed it out.

It has happened to me twice. I have no idea what caused it....just a electronic gremlin I guess.

If it is happening that often I would see it the dealer can pull any codes or records of it. Gl

The symptoms you have cited (Active Handling System warning and brakes locking up) could be the result of a wire issue in the steering column fixed by TSB 06-02-35-002B.

Yeah, I've heard about a TC/AH issue locking up brakes on certain C6 years. You should pursue the TSB and make sure you don't have this intermittent failure.

What I do not know (and am dying to know) is why does TSB 06-02-35-002 cover years 05-08 whereas Recall 10118 only cover 05-06.

Can anyone please explain this to us all? I thought that this TSB and recall were both aimed at the wiring coming apart in the steering column with a tilt and telescopic steering wheel.

I had the same problem. It turned out that the steering position sensor was bad.

Do you telescope the steering wheel often?

I've seen this problem mostly in older cars, but sometimes it's a rubber brake line starting to rot out from inside and cause a caliper to lock up. I've seen calipers start to freeze up too.

If this were caused by a mechanical problem with the brake lines, shutting the ignition off and turning it back on wouldn't fix it. This is an electrical problem, most likely associated with the active handling system, since it has the ability to apply the brakes electronically.

And if the active handling system engages, the DIC will say ACTIVE HANDLING for a couple of seconds afterwards. If the brake locking is being done by the traction control system, there will not be a DIC message. When a brake locks, the OP should immediately look for a DIC message.
