back end shakes when i press the brake

hello everyone, i am new here and am hoping to get some answers that other people couldnt tell me.

i bought a 1997 2.3L ranger xlt. it needed some parts, like brakes front and back and other general parts.

So i put in the brakes in the back(and it has been doing this since the old brakes) and when i lightly press the brake pedal down it shakes and jumps around quite a bit. it seem like it does it more when its warm. i checked the brakes out numerous times and everything is working right in the drums. also it only does it when i brake. so i am stumped on this problem. i am hoping i could get some feedback on this issue.

Thanks

Is it possible that the back brakes arent adjusted correctly and they are grabbing way to hard where the front brakes should actually be doing the majority of the work? I don't have a clue, I'm just taking a guess here.

Two possibilies, a warped drum or drums or brake residue on the braking surface.

well i just put new drums, pads, sprigs, etc in the back. so maybe its defective idk, but it had this problem with the old brakes.

Beyond me then, it is possible that one of the new drums is bad but if you had the problem before, you sure it isn't from the front? Warped front brakes won't necessarily cause the steering to wobble...

yeah i checked the front out too, we even warrantied the front rotors and tried those. were positive its in the back, i had my dad lay in the back while i drive it. haha

Maybe a loose backing plate? Also check all the u bolts on the axle, make sure everything is mounted solidly.

figured it out, bought a bad set of drums. just took them back and exchanged them. thanks for the input
