Brake Warning Light Question

[rusty79beast]

Ever since I changed the front brake pads on my 86 Blazer, the brake warning light will come on if i get on the brakes even a little hard. It never did this before I changed the brakes, so I was wondering what the problem is. The brakes don't stop as good as they used to either. Is it as easy as bleeding the brakes, or something bigger?
Thanks,
Paul

Either you master cylinder is going bad, or there is air in the lines, but if all you did was install new pads, i would lean more towards the master cylinder, sometimes of they are pretty old and you push those caliper cups back in too fast, it can damage them, done it before. /forums/images/graemlins/doah.gif
