before i replaced the rotor and pads, i have squeaking and shaking. i just put new rotors and pads on (front only). the squeaking is gone, but the car still shakes while braking. does that mean i should replace the rear pads and rotors too? or should i let the new front rotors and pads break-in a bit?
i bled the front brakes too.
thanx for any help, suggestion.

 

also, if there's still air in the system, it still wouldn't have cause the shaking would it?

 

could it be the caliper?

 

I'd let the fronts break in a bit first and watch to see if anything changes. Just because they're new shouldn't mean that they should shake, though. If the shuddering continues after the fronts are broken in, I'd inspect the rear rotors for warp and the pads for any abnormal wear. Also, are you sure you tightened everything down properly when you put it back together? As for air in the lines, if any did exist, your brakes most likely wouldn't work at all, or you'd get a majorly soft spot in your braking. So I don't think that's an issue in this scenario.

 

Is the car properly aligned and the wheels balanced?
