Raybestos® Advanced TechnologyTM Disc Brake Rotors

Each Raybestos® Advanced TechnologyTM disc brake rotor undergoes a strict measurement process to ensure it meets the strictest physical, safety and performance requirements.


Special coating increases life of the rotor
Special finishing process reduces noise and pedal pulsation
No break-in period required
OE metallurgy and design for optimal performance
Expanded coverage
Installation-ready – No turning or modification prior to installation
Full refund or replacement to rotor

Turned finish with RA 15 - 60

A properly machined finish does not require a non-directional finish
No turning required
Lower RA values result in less brake noise
Typical Economy rotors even with a ground non-directional finish has an RA up to 120 or higher
Lateral run-out of .002" or less

Results in less pulsation issues
Ready to install out of the box, no turningrequired
Typical Economy rotors exceed .004" run-out
Excessive run-out can cause friction material transfer after 5,000 - 7,000 miles
Thickness variation .0004"

Measured 360 degrees around the rotor, checking the nominal (out of the box) thickness
Excessive thickness variation can cause pulsation problems
Typical Economy rotors exceed .0005"
Parallelism of .002"

Confirms that both brake surfaces of the rotor are parallel to each other and to the rotor mounting face
Rotor turns straight inside the caliper, resulting in less pulsation issues
Economy rotors will go up to .004" parallelism
Specific Metallurgy

Damped Iron is always used where OE uses damped iron
Damped Iron is also used in noisy, problem applications
Black FusionTM Technology

Corrosion resistant coating
Tested in salt spray test ASTM-B117
Withstands equivalent of two snowbelt winters before rusting
Mill Balanced to 2 inch ounces

Less vibration, smoother braking
Economy rotor balancing varies widely, 3 - 4 inch ounces or higher
Cooling Vane configurations

100% match to the original rotor
OE design and metallurgy help rotor remain cool and quiet
