ihave 92 f-150 brakes shake real bad when applied ihave replced rear shoes cleaned every thing good checked front pads they looked fine don`t know what else it could be.thanks

 

warped rotors

 

thanks iwas going to try that itfeels like abs is trying to work but the light does`nt come on.i disconnected it on rear end but it did the same thing

 

get new rotors or get ur old ones resurfaced then throw them back on and that should have ur problem taken care of

 

+1 check the front rotors

 

Did you just replace the front pads? Then you used cheap pads.

If your brakes have been fine and they suddenly starting pulsating, then your rotors are warped. There are a couple different causes. Too thin, overtorqued lugs, and excessive heat are the most common. If the heat was too much you'll see tiny cracks and hot spots on the rotor surface.

 

i have replaced rotors and put on new pads and it is still doing the same thing i have also replaced rear shoes i don`t what else to do thanks for any help

 

igot the grakes fixed ended up being left rear drum out of round had it turned and everything is good now.
