So I had an issue with my front brakes a few weeks ago with my brakes locking up. I learned that i need to change my brake lines. I recently discover a couple days ago that now when i hit the brakes there is a weird clunking sound coming from what sounds like the rear axle. Also when i try to back up there is a little difficulty backing up. Could it be the brake lines also or something else. Keep in mind this is not a daily driver so the only driving i do in it now is around my property. Thanks for your help guys.

 

Might be something with the self-adjusters in the rears (assuming it's a drum rear).

 

yea there are drums in the rear

 

I'd make sure there is nothing broken inside the drums, then adjust the shoes. Does the parking brake work?
