This video shows how to correct for brake vibration caused by DTV (Disc thickness variation). DTV develops in a car after 3000-4000 miles caused by runout built in to the car or due to incorrect alignment of the rotors at install. This is quite a common fault on modern cars and many cars require this at every rotor change. Drivers also confuse hub distortion with a rotor quality issue but in 99% of cases the DTV is a car problem, not a rotor quality problem. You can replace the rotors as many times as you like trying to solve
vibration and the problem will only go away for a few thousand miles and then return. This means you have purchased new rotors in good faith but the problem IS NOT SOLVED AND WILL NOT GO AWAY PERMANENTLY until you perform this procedure. After this skimming of the rotor surface you will have smooth brakes , more effective brakes and ZERO vibration. It is even a very worthwhile practice when fitting new rotors to have all four rotors skimmed into perfect alignment on your car with this inexpensive procedure.

Pro Cut machines WORK ON BOTH PLAIN ROTORS AND EVEN BETTER ON SLOTTED AND DRILLED ROTORS OF ALL TYPES

Who are Pro-Cut ????... Pro Cut are a USA based multi national and extremely professional Corporation. Their machines are used and approved by many major car manufacturers and used all over the world to do exactly what they do best, CORRECT for rotor mis-alignment no matter how it arises on a car. You cannot achieve this with any other device.

Benefits of aligning discs with a Pro Cut lathe EVEN FROM FIRST INSTALL

Even when fitting NEW discs or rotors there can be runout from first install due to hub and vehicle chassis alignment tolerances and the perfect way to guarantee smooth braking from first install is to have even your NEW rotors skimmed. Because the rotors are new this will only take the smallest amount of material from the disc……a maximum of 5 thousandths of an inch and will not affect disc or rotor service life.

What a skim over from new with a Pro Cut lathe will do is

1. Perfectly align your discs or rotors to your car
2. Ensure smooth and perfect braking from first pedal
3. Remove zinc from the braking area accelerating bed in and brake efficiency
4. Prevent DTV and brake vibration occurring for many thousands of miles

EBC Brakes recommends, endorses and approves Pro Cut brake lathes and their use not just as a solution for brake vibration but as a means of perfecting rotor alignment from new install.
