89 Blazer, break light in dash flashing

[toxicFrost]

I bought a 89 Blazer a few weeks ago and the guy told me he does not know why the break light in the dash stays on, we went over the break system and many parts have been replaced.

Yesterday the light started blinking, one long 3 short, the breaks still work, fluid is full and I checked each wheel and could not find any fluid leaking.

Can someone tell me what this code is so I can get the light to stop blinking?

Thanks for any help

Welcome aboard Toxic, does that mean the yellow snow? haha
Mine did this once and I learned that it is caused by the sensor on the proportioning valve under the master brake cylinder . at some point , the front or back half of the brake system had a fluid loss , or air in the line causing the piston to move out of the center . I am not sure how I corrected it due to it happened 2+ years ago . I know I unplugged the sensor and pumped the brakes alot and may have even disconnected the battery . Hope this helps . Rob

Hey Rob thanks for the help, I know what your talking about I was looking at it yesterday thinking that might have something to do with it.

Yellow Snow I never thought of that... I like it
