When I apply the brakes the car shakes...

what's up with that? Since I have done a front brake job (didn't do anything to the rotors), the car shakes when I apply the brakes. This shaking / rattling is increased as the speed increases. Do I need to turn the rotors?

Thanks,
M.

Was the car shakeing before? Yes=rotors. No=maybe/maybe not rotors. Did you bed the pads correctly? Over torque/unevenly torque bolts thus warping rotors

Thank you guys for your responses. The car wasn't shaking before. But I didn't use any torque wrench to set the pads either. Can I use light sand paper on the rotors?

Hi -
I should have asked, what does turning the rotor entail? Can this be at home with basic tools, or should I take it to a mechanic?

Thanks,
M.

Turning the rotor involves using a lathe-type machine to rotate the rotor as a cutting bit shaves off the high spots on the rotor. This can only be done a couple of times before the rotor reaches its minimum specified thickness. These days this is done with the rotor still on the car.

I have never had luck with getting my rotors turned. Since you are shaving down the rotor to get it even, you loose more metal, making it thinner than before, thus easier (in my book) to warp again.

I can't remember how much it cost me to have mine turned last time (it was years ago) but for the cost of new rotors, I just replace them and try to drive easier (for a while).

Check out www.nopi.com new Brembo rotors are $31 each. I haven't had rotors turned on car but the last time I took rotors off and had them turned it cost me $12.50 per rotor. That was over 5 years ago and I am sure it costs more to turn them on the car. It makes dollars and sense to upgrade to new Brembo rotors for $31.

Before you get new rotors or turned take a fine sandpaper and sand the surface. When you brake pad material is deposited on the rotor. If you do not bed the pads or rotors correctly you can get spots that have more pad material than other areas causing a warped rotor feel.
