braking noise

everytime i apply the brakes i can feel something thumping through the brake pedal and i can also hear it. i just installed a 3'' rustys lift and i have never noticed this b4 i put the lift in...any ideas of what is causing it? my e-brake cables are stretched to the max but other then that i cant see anything

sounds like warped rotors

pull a tire off and look at them..

the noise sounds like it is coming from the rear but i have drums in the rear which are only a few weeks old....also when ever i go over bumps it sounds liek somethign is loose in the rear end but i made sure to tighten all the bolts when we installed the new lift so im lost with what could be causing that

pull the drum off

i blew up the pin that holds the upper return springs together (it snaped off in an e-brake slide... [dont ask])

all the springs should be attached on both ends...

spray some brake cleaner in there and pop it back together...
