When ever I hit the brakes hard the "Brake Light" comes on & go back off for a split second. What is it? I was thinking a sensor for someting like that.., Any info. is good info...,

Thanks,

There's no info in your post about what car you are driving, year, etc. It is it the ABS light or another "Brake Light"?

With so little description, it's hard to tell, but it could be several things:

1) Low break fluid level in the reservoir. It is not low enough to cause the light to stay on full time, but when you break hard, the fluid sloshes around enough that the low level indicator lamp comes on. Check the dipstick and see if you need to add fluid. If so, use the appropriate fluid to top off. Also, if the fluid is low, it may be indicative of a leak.

2) Loose wire on one of the break lights that moves when you break hard causing the car to think that one of the break lights is out and thus it is giving you the indicator lamp.

3) If it is the ABS light, there could be a potential problem with your ABS system and/or pump. This could be a seriously expensive repair. My cousin just told me that his Honda ABS pump went out, and the dealership wanted @ $1200 to install a new one.

it's #1.

Toyo/Lexus brake fluid level senors are very touchy and will indicate that the fluid is low even when the level is above the min. mark.

Just add a little DOT III fluid to the reservoir.

DON'T get this fluid on your paint as it will strip it right off.
