My brakes on my older Chevy seem to work fine, but several times lately when I've had to brake fast, the brake light comes on. On normal braking it does not come on. The master cylinder fluid is full, and there are no leaks in the lines that can be seen. The car has a proportioning valve, and I assume that valve is not getting even pressure to cause the light to come on. The question is why? Could the master cylinder be bad, yet still stop the car properly? This has me puzzled.
