Front Rotors and Hubs

[Rudy van Daalen Wetters]

John,

My own experience indicates otherwise
and most good shops insist on balancing
them together. I go with what works for
me.

Also shops that skim discs (one should be very careful here) have machines that are designed to work with a disc that has a hub. They would not be able to do just the disc alone ... ie. they do NOT just use a lathe.

The other reason to keep the hub and disc together is if the hub and/or disc bolting face is NOT perfectly square it does not matter, because the machined disc surface IS perfectly square to the centreline of the hub if surfaced with the hub still intact.

Also regarding plating high tensile bolts ... please remember to degas them. Search the net and you will find what I mean, as plating bolts makes them a tiny bit brittle.

I also do NOT think Ferrari would have plated brake disc bolts originally OR painted any surface of any brake disc or drum ... pointless exercise when the car is used as a car.

Hydrogen embrittlement occurs if a high tensile piece of steel (such as a bolt) is electro plated. Here is a link: http://corrosion-doctors.org/Forms-HIC/ ... lement.htm
