Arrow Rear Caliper Drag...Brake lines????

I noticed both rear discs had scoring damage on them, further inspeciton I noticed the top of the pads & pad clips, on both outer sides of the discs, were digging into my rotors. The inside face of the rotors are fine, just on the rim side is where the pads/hardware are digging in.

Put on new rotors & pads, lubbed my caliper slide pins (which were well lubed to begine with, so they weren't dragging...) Took it around the block, then looked at my rear rotors and low and behold they both got a nice, almost lathe like grove all the way around on both disks.
And again, the tops of the pads/pad hardware is gouging into the disk, and the lower half of the pad is barely contacting.

Read on here that the hoses can errode over time and create a baffle/check-valve like effect on calipers and could cause brakes to slowley dissengage, if at all. So I started with bleeding the brake system, I've never bled the system on this truck and it was nasty.
It smelled like the inside of an old rubber hose, and the fluid was dark green like swamp water. I flushed and flushed, and it's still a light tint of green...

My question is, could my brake lines be causing this, and if so, where do you buy lines for a lifted truck?!?! I have an 8" lift. I've looked online and couldn't find what I was looking for. And no one locally with make any...liability I guess....

Thanks for your held guys.

Well you're correct... a hose can degrade internally and hang up a caliper... had an F-150 do that to us. And normally, you go right to the caliper like you did. So, it is for sure possible.

As for where to buy lines for a lifted truck, I can't help.

But if you've run through the caliper and it seems fine, a hose change could help.

Try to find a business that make hydralic hoses in your area. They should be able to make you new hoses.

Just an update....

Got new rear Calipers, as well as found a place that built steel braded lines....I'll be installing that this weekend if I don't get caught up with other projects...I'll post results, weather they be good or bad.
