new brake/rotor question.?

Postby bigtinybob [OP] » Nov 21 2014, 2:25pm

about 3 weeks ago i put new brake pads on the front of my 08 silverado,after driving for awhile and going down a mountain i notice a real bad vibration .so i put 2 new rotors on after driving for awhile again i noticed that it still has the vibration but only when i go down a hill,it doesnt do it right away but when im about half way down the hill,like they are getting hot or something.any ideal?could i have a bad out of the box rotor?

and also when i install the inner pad into the bracket,i have to push really hard ,sometimes tap it with a hammer to get it to slide in,the outer one slides in fine.is this normal .the last 2 sets i have put on has been this way.

It could be the rear drums that are getting out of round when they heat up.

You could feel it some in the steering wheel, but if it were the brake drums, it would not be really obvious in the steering wheel. I'd suspect possibly a bad tire or you have warped the rotors again.

I usually set them where they lightly drag.

Did you bed in the new pads correctly? If not, you can get pad material unevenly deposited onto the rotor, which can cause a pulsating pedal. You can usually see this as dark streaks on the rotor surface.

nothing on rotor,checked them also,only does it when they get hot,and seeing that my rear shoes wear almost metal.ive only had front braking basically for awhile now.and since its single spring it wont take to long.is it easier to disconnect the parking brake under the driver side when replacing the shoes.seen some videos on youtube .some did it some didnt? and also on the front pads the inner pad on both side was hard getting out and putting back in.is this normal ? sorry for all the ? but this is my DD
