Dash Lights
Whenever I apply medium pressure on my brakes, coming up to a stoplight after exiting highway or something where its good amount of braking but not stomping on the brakes (but stomping also applys); Then seems to almost always trigger my service ASR and service ABS light. And this morning it also for a brief second, triggered my low coolant light.
Where should I start and what kind of costs am I looking at?
Thanks for any help, im learning about my first vette ever still.
Its a 1993 LT1 40th Annv.

C4s trap air in the cooling system and need to be burped to get it out. Starting cold, loosen the rad cap to its stop (where you have to push down to turn the last bit), start engine and let it idle to the opening temp of the thermostat. Pull on the throttle end stop on the end of the MAF to race the engine slightly and remove the rad cap. As you rev the engine you will notice that the coolant is flowing and drops it level. While reving, pour antifreeze mix into the filler until it comes up to the neck and replace the rad cap and let the engine back to idle.

Does this have to do just with the cooling light coming on the one time? Or does it have to do with the other lights as well? My car is really having trouble somewhere, I have yet to change the plugs and wires, but its on the agenda next, because the car is supercharged but really not running any faster than a stock c4, and Im trying to figure out why. Could the plugs and wires have this big of an impact?

Check your manual to see if low brake pressure in one circuit will trip those lights. On mine it trips the e-brake warning light, but I have no ABS lights. If that's the case you could have a failing m/c and not even know it.
The low coolant light is probably getting airbound when the coolant sloshes away during braking. How is the coolant level? Does the overflow tank go from cold to hot level?
