Has anyone here ever got brand new rotors that were warped?
A month ago I bought Power Stop Rotors and Pads from Auto Anything, and installed them three days ago. Two days of driving and the front end shakes really bad when braking from over 45mph. This morning I took the car to a Brake shop and they drove the car put it on the lift and told me the front rotors are warped. Any thoughts?

Thanks

 

Can IMPROPER bed-in procedure cause warped rotors?
lifetime warranty?

 

If your asking if I installed them propperly, I am quite sure I did. I sanded the surface that the rotor rests on. Everything was torqued propperly. There is less than 50 miles on the brakes.

 

I'm asking if you bed them in properly.

 

I have no idea what that means. Any time I have ever done brakes, the same process was used. Install them properly and drive with no problems. So call me DUMB but what is bedding them mean?

 

you're not dumb.

 

OK, but can you explain bedding brakes before I search?

 

I always do step one and two, but always just called it breaking them in. I don't think not doing this would warp the rotors though.

This is from the PowewrStop site:

Brake Pad Break-In Procedure

IMPORTANT: BREAK IN NEW BRAKE PADS/ROTORS USING THE PAD BEDDING PROCEDURE AS FOLLOWS. PROPER PAD BEDDING CAN PREVENT ROTOR WARPING.

The break in procedure is critical to brake performance. The reason for a proper break in is to establish an even layer of friction material deposited on the rotors from the brake pads. It is very important that this initial layer of friction material is evenly distributed. Break in the pads as follows: 5 moderate to aggressive stops from 40 mph down to 10 mph in rapid succession without letting the brakes cool and do not come to a complete stop. Then do 5 moderate stops from 35 mph to 5 mph in rapid succession without letting the brakes cool. You should expect to smell some resin as the brakes get hot. After this is complete, drive around for as long as possible without excessively heating the brakes and without coming to a complete stop (Try for about 5 minutes at moderate speed). This is the cooling stage. It allows the heated resin in the brake pads to cool and cure. After the brakes have cooled to standard operating temperature, you may use the brakes normally.

Chances are your rotors are not warped, but the pad material has a buildup in various spots on the rotors and this is creating the pulsation.
