[kc 93'ls]

My brake light on the dash has been coming on when I hit the brakes hard. The level in the master cylinder is full???

Is there anything else on that lighting circuit besides the brake fluid level sensor?

Thanks KC

depending on the year, it might be indicating a bulb out (or one of the filaments (2 for each bulb, 4 bulbs total)

also - open the cap to make sure its full, and top it off just to be safe.. its chambered inside, and is more than possible for the clutch portion to be ok.. or at least look ok from the outside... and the brake portion to be low.

My car is a 93 ls.... the level in the master cylinder full. I'll check the bulb today.

Time to change your brake pads...

I am getting the same thing with my '93 and my brake pads are fine...not sure what it could be

we have no pad-wear indicator in our dash.

i've had my pads down to the nubs and assuming the fluid level is ok, the extra travel of the caliepr's piston that extremely worn pads would cause, still wouldnt be enough to 1/2 empty that resevior and trigger a light...

again, you might be absolutely right only if his fluid isnt properly filled, or there is a ton of air in the system that the fluid has to make up for before it hits the pistons.
