Hello. I have an 06 Silverado 4x4. Recently replaced rear drake drums and front rotors along with all brake pads and shoes.
I now have a bad vibration when braking. No pulsation in the peddle but the truck shake in an up and down motion.
Any help would be very useful.
thank you

 

I'd revisit what you did when replacing the rotors, is everything back together correctly, etc.

 

If the pedal doesn't pulse, then it won't be rotors.

I would check the tires for irregularities and get the wheels balanced.

 

None of this started until the brakes where replaced.
the tires are Bridgestone Dualers 95%. It’s weird.
It almost feels like a bias ply tires.

 

Go back and give everything a once over.

 

rims not seated properly or not tighten down right

 

Turned out to be defective drums from Napa. Took three sets to find a set that wasn’t defective.
thanks for the help..

 

front brakes will transfer into the steering wheel
rear brakes will transfer thru the floor of the vehicle and pedal.
if you bought the cheap line ac delco advantage drums...they will be 0.010" out of round right out of the box. This happened to me repeatedly with these drums....now I put them on a lathe to check them before installation.
take it back to the dealer and let them correct it.
