Front end vibration when stopping at high speed

JARblue

Drive 60 mph, brake as hard as possible WITHOUT ENGAGING ABS down to 15-20 mph. Repeat 60 mph down to 10 mph. Repeat 60 mph down to 5 mph. Do enough runs to heat up the pads and rotors nice and hot. DO NOT COME TO A COMPLETE STOP WITH THE BRAKE PEDAL PRESSED during this procedure. Doing so will cause the hot pad material to deposit in one location on the rotor, which is the most common cause of so-called "warped rotors".

The key is to heat up the pad material enough so the uneven portion can be leveled off with hard braking. When new pads and rotors are installed, the purpose of this process is to distribute an even layer of new pad material onto the new rotors which allows the brakes to function properly.

If you're not comfortable doing this procedure yourself, a qualified shop can turn the rotors for you.
