GMT400 ABS/Brake Hop

[bcrooms]

Am I the only one that notices how bad the GMT400s "hop" when slowing down?  Mine does it every single time around the 45-50mph mark.  it stops once the truck is slower than 45mph.

 

I do feel the brake pedal pulsing while this occurs so that seems to be the ABS system.

 

Is there any remedy to make this smoother on a 97 K1500?

 

Thanks,

Brandon

Sounds like you have a warped rotor.
