2. Lap the track in this manner until you start smelling

the brakes. Continue for another ½ lap at speed, then

do a two lap cool down with minimal brake applica-

tion. Make sure the brakes are not smoking. If they are,

do another cool down lap.

3. Do not continue for more than one full burnishing lap

after you start smelling the brakes. Do not get them

smoking heavily. This will get them too hot and will

negatively affect their life in future track use.

4. Allow the vehicle to sit and cool in the paddock for at

least 30 minutes. If an infrared thermal gun is avail-

able, allow the rotors to cool to 200° F (93.3° C) before

going back out.

5. There should be a thin, ashy layer when inspecting the

pads installed in the caliper. If the ash layer is more

than ½ the thickness of the brake pad material, this is

an indication of too aggressive of a burnish.

6. Sometimes, a second burnish session is required. If the

brake pads start smelling in the next track session,

reduce speed and braking deceleration to burnish

targets and follow steps 2 through 4.

7. New brake pads installed on old rotors still need to be

burnished. New rotors installed with old pads should

be burnished at the track, or street driven for 300 city

miles, to develop an adequate lining transfer layer on

the rotor surface prior to track use.

8. Rotors that pulsate during track use should be re-

placed. Resurfacing of the rotors is not recommended,

as it removes mass from the rotor, reducing its thermal

capacity. Resurfacing also thins the rotor cheek, mak-

ing it less robust and increasing the likelihood of

pulsation in further track use.
