brake question

I just replaced the front brake rotors and pads on my '97 F-150 4x4 and I am still feeling a pulsing in the brake pedal. Has anyone experienced this?

Are you sure the pulsation is from the front?
Warped rear drums can cause it too.

I agree with the warped drums. You can test them by slowly stopping only using your e brake. Do this in a quiet area of town and you only need to travel at 5 mph. If the drums are warped you will probably feel the whole truck lurching/surging.

1997 f150 173000 miles.

recently the truck has had a clunking noise when applying the brakes, so today i gently but steadily applied emergency brake while driving around 40 mph. while pushing on the ebrake and about a 1/4 of the way down, i hear a loud "clunk" which sounded exactly like the clunks i heard before. I tried it 3 times and each time i heard the clunk. the clunk seems to come from the rear of the truck.

This truck has front disc and rear drum brakes. No ABS light on.

I replaced rear shoes at around 100k but otherwise the rear brakes are stock. I've also recently experienced some mild pulsation when braking but my front rotors are i think in good shape so from Racerguy's comments the rear drums may need turning. Easy to think the problem is just rear drums but before i take them off would like to hear your ideas i.e. is maybe the
e cable at fault or ?

thanks for any suggestion.

Question

Ok, I replaced the front brakes and rotors, bled the front brakes, replaced the rear drums and still have the pulsation. WTF?

Any ideas?
