I replaced the front brake calipers and now the brake warning light stays on and also the cruise control will not set, all after the brake job, the brakes work fine. Is there a way to reset brakes and get cruise to work?

So the brake light was not on before you replaced the calipers? You should not have to reset the brake light. did you make sure the brake fluid level was not low?

I posted the description of the brake warning light for you. It is turned on by low brake fluid or e-brake on. So if the e-brake is released and brake fluid is not low you could have a switch issue.

Not sure about the cruise control not working. you would have to diagnose that separate. When the fluid level is full the light should turn off. i suspect the float in the master cylinder is sticking since you said this happened after you replaced the calipers.

I agree with Saturntech9. Try rapping on the side of the brake fluid reservoir with a screwdriver handle and see if it puts the light out.

Yeah, the PCM will inhibit the cruise as long as the brake light is on.
