Brakes

[MidnightBlade]

Probably a bad sensor somewhere in the rear brake components, or it shares the same symptom as alot of new vehicles, you hit a bump in the road and the ABS light comes on. Only problem is I don't know what causes the light to come on with the newer vehicles

where are the sensors at on this system? I don't know of any WS sensors. I thought there might be a vaccum sensor somwhere, but I couldn't find one.

I think their is a RABS sensor on the rear but don't know for sure. As for the red brake light that comes on when the parking brake is on and will also come on with a vacum problem or a hydraulic leak problem.

the light that's on is the orange "rear abs" bottom right corner of the cluster

Read this article. Although it is for a Ford Bronco it applies to our trucks as well.

that does help. I noticed the pedal fading off, but never really paid any attention to it. I blocked off the master cylinder like it said and had a solid pedal. I hooked up the rear lines only and it bled off again. The brakes still work good so I don't think I'm gonna worry with that right now, I wonder if one of those solenoids will cause the light to come on?

If your referring to the solenoids and meaning the RABS valve the answer is yes.

The RABS valve has an electrical connection to it and is located on the frame rail towards the front of the truck on the drivers side.

It will look like the one in the pic.

well, i found out why the light was on... The PO pulled the fuse.... I'm sure it was either because he needed the fuse somewhere else, or more likely because he didn't want the RABS to kick in. Either way, I can't stand to have any lights on, unless I pull the switch. I put the fuse back in and bypassed the valve. Now the light is off and the pedal dosen't bleed off and I didn't spend $200 for a new valve.

sorry for being a dead thread. i have this issue among other issues.

the missing fuse would turn on the abs light? where is it?

It was one of the fuses in the fuse block in the cab, I don;t remember exactly which one but I think It was labled abs
