ABS and brake warning light both intermittently turn on?

When I apply my brakes in reverse there is a horrible grind but not the normal brake pad grinding like when brake pads need replaced or are dragging, it's a much bigger grinding noise. It started suddenly out of nowhere and I believe it is coming from the front underneath. Everything is normal and fine when backing up until I apply the brakes. This does not happen any other time. Shortly after hearing the grinding noise, I began to hear a raddling noise from under my truck that seemed to get louder or worse. The raddle seems to come from the front underneath area. (Cannot hear it when only back window was down. Can hear it very well when only the front window is down) The raddle noise only happens while driving or in motion. Don' know if noise continues after gaining speed my truck is modified to be a loud running vehicle. So not being able to hear the raddle at higher speeds is not necessarily because it isn't making the noise. It could just be that's its being drowned out by a louder noise.
both front rotors, brake pads, brake calipers all that have been replaced and are brand new. Also, both front CV axles have been replaced. Already checked transfer case and it's full. Just had a complete changing of all vehicle fluids and air filter dash filter all that stuff Oil Stop does. My truck does have two separate lift kits on it with a modified exhaust system. Oh, and the battery is new.
Do you
have the same problem?

It sounds like the e-brake shoes in the rear are having issues which are common on these trucks. Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. Also, on the noise in the front I would replace the front bearing hubs are videos to show you how and what to look for when doing the repairs, use AC Delco parts.




Let us know what happens and please upload pictures or videos of the problem.
