Hey guys just wondering whats going on here i know it can't be my drums cause i did some braking with the e brake and it wouldn't thump then. Times when it does it is after a little bit of driving say around 10 minutes plus the thumping will speed up when i slow down to like 20-10 mph

i am thinking it maybe the front brakes not sure of what could be wrong maybe the rotor is off or my rim is out of round help please

if a shop just did the brakes take it back and tell them to fix there screw up...

rim would be noticible all the time. when you say thumping. is it an audible noise or something you feel in the pedal?

check to make sure all the caliper bolts are present and tight.

otherwise it could be the piston.

also try greasing the sliders on the calipers... suppose to be done on a brake job anyway... and greasing the back of the pads... people think autozone trying to sell you that brake grease is a joke... i used to think that until a altima was killing me at nissan with this issue... i never used grease... my senior mech told me to try it since everything was new and sure enough... its important... always use it now...

the thump is audible and it pulses too through the pedal but only slightly

sounds like your front calipers are sticking and staying up against the rotors... which are warped... hints the pulsating... need to grease the sliders... or replace the calipers if there to bad...
