It's a 06 GMC Sierra cc and the other day my ABS and E-brake lights came on at the same time. Now everywhere I go they come on for a few seconds then back off. They are not affecting anything besides it's damn annoying. Has anyone have this problem before. Any help please thanks

 

the brake comes on to warn of an issue which is abs related, is your truck lifted? or modded with gears or anything?

 

I just had the same issue, I thought it was because of my gear change but when I jacked up the truck to do the front diff I found that I had a left front hub going bad. I replaced the hub but haven't finished with the front diff gear change yet but if I were you I would at least jack up the truck and check the wheel bearings and see if they are sloppy.

 

The truck is not lifted or modded. It does pull to the right as it needs an alignment. The other day I ran my power wire for my amp through the boot for the e-brake cable underneath carpet. Thats when It started doing it that day. I don't believe that affected it though. Maybe its just a bad hub. Thanks for the quick replies.

 

check the ground cables on the frame under the drivers door to make sure that they have good connection

 

Check your brake fluid and try bleeding your brakes.

 

Thanks for the suggestions guys I will check it out. I haven't checked my fluid in a while but my pedal feels softer as in I have to push it in further now.
