I own a 88 SSE with 204k kilometer.
Great machine to play with, however the following glitch I have
is not giving me much confidence in the braking system.

When I am into traffic bumpers to bumpers for about 30 minutes
and up...the warning lights "brakes & Antilock" suddently lights up...
when I recover normal highway speed then the lights go off.
Kind of scary!!!
My brakes have been renewed and I wonder if there is a cure
for this annoying signals showing off my brakes system weaknesses and help me recovering my trust in this car.

Is there anybody that have lived this before and could bring
a solution for this?

No change on the pedal...except that few years ago the
ABS shut off and the brakes system went into a madness in the middle of the city and it was very scary to brake with unassisted
brakes for a while...shut off the engine and waited 15 minutes and the braking system re-armed ..but what a pitty experience....
What GM taught when they ingeneered this?

Yes, the bleeding was done properly on it...brakes works fine
but the dam warning lights scare me alot when they lights..

No change on the pedal but I guess that if I still have to used in the traffic for too long that the brakes system failure will occur again.
Quite dubius that a car of this quality could have this type
of problem.
I wonder if GM had a Special Bulletin on this?

How do you appreciate that kind of brakes failure?
