when stopping brake light comes on and antilock brakes come on
If I had those symptoms, I would drive–very slowly–to a qualified mechanic’s shop the same day, and I suggest that you do the same. The problem could be as simple as a low level of brake fluid, or as complex as… God only knows. And, if the brake fluid is low, that could indicate a leak in the brake hydraulic system, and that is certainly not something to take lightly.
Check the brake fluid level.
