I just picked up a 2005 sierra rcsb. when you brake it has a vibration or shutter in the front. The seller just recently installed new front rotors. What else would cause this other than warped rotors? Its not that bad but damn its annoying.

 

Loose caliper, didn't clean the hub when new rotor installed. Just idea's.

Does it have rear disc brakes or drums?? Being a 05, I'd guess at drums.

Also does the brake pedal pulse or is it through the steering wheel you feel it??

 

Its more through the truck. Tonight was really the first time I drove the truck much when I drove it into work. The truck has 156k miles on it. I know on the older chevys they had like a pitman arm or something that would cause this. I just don't want to start changing out parts to find it. Ill try to pay closer attention to it in the morning on the way home and post back up.

Yeah rear drums

 

Have the rotors turned.

There never tru out of the box.

Some brands are better than others but I usually find they require being turned for optimum performance.

 

The vibration is pretty minor but it makes some thing under the dash rattle so it's annoying
