Just got home from a five-day, 700 mile trip. Running in stop-and-go traffic, I hit the brakes hard enough to lock up at least one rear wheel at about 30mph. Thirty miles later I pulled off the freeway to stretch my legs and as I applied the brakes I felt a little "bump" in the pedal and then had to really step on the brakes as it felt like there was no vacuum assist (I have an electric vacuum pump). The red "Brake" light came on. I checked the fluid and both reservoirs seemed full. I had pedal pressure and was able to stop at a stop sign without excessive pressure so I drove the remaining 150 miles home - very carefully. I used the brakes as little as possible but every time I touched them they seemed normal. Coming off the freeway I was able to slow and stop normally although I gave myself a lot of room and a little help from second gear, just in case.

When I got home I checked the fluid again and both reservoirs were about where they had been. The vacuum pump seems to be working. The rear brakes were done by Applied GMC about 1,000 miles ago including replacement of at least one wheel cylinder. Front brakes seem OK but I don't know when or if they were replaced (60,000 miles on coach). Brake lines are all original.

What triggers the warning light to come on? What kind of problem should I be looking for?
