You think is that problem

 

Yes.

 

You can't change the pads without at least having the rotors turned. I always replace both at the same time since the parts are cheap. Sounds like the rotors are warped. Change them out.

 

Thx

 

100% change your rotors even if they look good or someone told you they are good.

If the problem still occurs, do you have a spare tire? If you do, put the spare on the frost of the truck and see if that solves the issue. If not, try the other side (front driver and passenger). If that solves your issue, you need a new tire. If not, It sure sounds like a warped rotor and I have no clue what to tell you if the rotors are good.

 

I will try change a rotors
Thx

 

Hello guys
Is me again...i see today first time my ABS doesn't work
Maybe is that problem for pulsing pedal?
Thx

 

Did you replace the rotors?

 

Not yet...my brake still pulsing on pedal when i want to stop. No shaking on sterling. And today i see my ABS doesn't work

 

It could be a bad wheel bearing, but I'm still willing to bet it's the rotor causing the vibrating. You can check for a bad wheel bearing yourself. Do a search on Google, that will give you enough info to check yourself. Either that or take it to a repair shop for diagnosis. Shouldn't cost very much to find a problem like that.
