Centric 12058009 Premium Brake Rotor
Centric Premium Rotors are blank, 1-piece, direct replacement
discs for your factory brake system. These ?black? rotors feature a
special anti-corrosion e-coating that gives them their distinctive
look and name, and are manufactured under QS and ISO quality system
standards. StopTech Premium Rotors are particularly desirable in
fleet or emergency vehicle applications when an upgrade to Power
Slot or SportStop performance replacement rotors is not
possible.
Like many StopTech, Power Slot and SportStop rotors, Centric
Premium Rotors offer several key advantages over stock rotors,
E-coating, Double Disc Ground, Machined Finishes, Split Castings
and Mill Balancing are just some of the processes we use.
E-Coat Finish
Centric premium rotors utilize an electrocoating finish that
provides long lasting corrosion protection. E-coating is a superior
electro-statically applied finish designed to withstand 400 hours
of salt water exposure without rusting. Finishes used by other
manufacturers provide only minimal protection from the elements and
are generally only effective for the shipping and storage portion
of a rotor?s life. The addition of heat and moisture eliminates the
effectiveness of many of those finishes resulting in immediate
corrosion once installed in the vehicle.
Double Disc Ground Braking Surface
Nearly all Centric premium rotors feature a double disc ground,
taper free finish. Double disc grinding ensures parallelism,
eliminates run out and provides near perfect disc thickness
variation (DTV). Double disc grinding
leaves a non-directional finish on the friction surface area for
more effective pad-rotor break in. This special finish also
provides quieter and smoother stops.
Fully Machined Hats Centric
Premium rotors feature 100 percent fully machined finishes
including rotor hats. This extra process provides better rotor
balance and creates a cleaner, more finished looking component.
Center Split Casting
The profile of the rotor?s cooling vane affects its ability to
dissipate heat. Ideally the vane should have the same thickness at
the points where it connects to the inner and outer friction
plates. This is accomplished with center-split core castings that
provide proper heat transfer and thermal efficiency. This thickness
symmetry in the vane promotes the uniform transfer of heat from
both friction plates into the cooling vanes. Competitors? vanes are
often asymmetrical, which can lead to uneven heat transfer and
compromises in performance and cooling.
