Track Prep

[Phokaioglaukos]

For cross-drilled rotors I replace when cracks are about to connect hole to hole or to the circumference.

For slotted rotors I replace when the slots are about to no longer be slots.

(I use slotted rotors--they last longer.)

I have just had a good experience learning how to judge when wheel bearing need replacement: when they spin at all freely. the catch is that the axles need to be out of the rear to allow the test. Play is also a replacement indicator, but I felt none and that appears to be common. On a race car one needs to replace wheel bearings, and many other parts, based on hours of use. Just ask Corey....
