I just replaced all four corners pads and rotors with the Power Stop Economy kit off Rock Auto and I'm having horrible shaking while braking at highway speeds. All slide pins have been re-greased and appear to have been in good order. On a hunch I replaced the front slide pin boots and it's still shaking. I'm contemplating re-jacking the car and replacing the slide pin boots on the rears, but I'm just not sure that the issue is the slide pins. Any idea on further troubleshooting before I just drop it off at the local mechanic?
Thanks in advance!
