ABS & Brake warning lights

I'd push very hard on the brake pedal when vehicle is running PARKED , then look for a puddle of fluid under the truck. Did you check the brake fluid level? Those WARNING lights usually mean the vehicle has a problem. How would you feel if something tragic happened?

Actually, those lights on together mean that there is something wrong with the anti-lock system which may or may not be major. In most cases, it indicates that the speed sensor in the rear axle has failed but that is not always the case. Either way, at worst it indicates that your anti-lock system is no longer functional and if you have just the rear anti-lock brakes, I don't see it as any real loss at all. It is unlikely that the anti-brake light would illuminate due to a fluid leak.

Fluid level is fine. There are no leaks.

Thanks, TBone. I took it out for a drive after my daughter told me the lights came on. I put the brakes on really hard several times and it stopped OK. The rear axle speed sensor was the first thing that came to my mind. I'm tempted to change the sensor and clear the codes just to see if that's the problem, otherwise, I'll get the garage I have do things I can't or don't want to do myself scan it and go from there. Thanks again.

well well , fords are a bit different w/the warning lights then , guess you know who is the ass this time when i a$$ume d. my bad the op did look anyway ( for leakage ) which would make me feel alot better about using my truck w/the warnings lit.

After I checked for leaks and appreciable change in the fluid level (none) and taking it for a drive and applying the brakes hard several times I felt pretty confident that it would be safe. But before I let my daughter drive it to school (4.5 miles) I figured that I may as well avail myself of the knowledge and kindness of this group. There are several here that consistently give good advice (TBone being one of them). I do appreciate your concern and tendency to go to a safety first position.

That's what I did, when the lights were on and I couldn't get a OBDII failure code. After changing the sensor, lights went out.

I think I'm just going to go ahead and change the sensor. For the cost it will likely be the most time effective thing to do.

Thanks for the reply.
