New here guy and cant figure how to post. I have a 1997 Blazer 4x4. Just replaced brake booster and brake switch and now brake lights wont go off. Any help would be great. sadsack24@hotmail.com

 

sw assy's binding. should be straight back from, aligned and square with, booster shaft



Booster shaft on end of pedal pin, slide U of sw over and down onto pin push inward.

Also check for the designed play between pedal pin and booster shaft. If booster shaft pushes toward pin, could be the problem.
