I have A 2003 Chevy Silverado.
I reaplaced brakes and rotors on the front.
When i applied the brakes the front passenger side felt as if i had a wrped
rotor. I swapped rotors expecting the problem to switch to the drivers side but it still was on the passenger side. The problem only occurs when i apply the brakes. When applying the brakes its as if they are locking up and then releasing only on the passenger front side. Help.........

 

Sounds like you got a sticking caliper.
