Better brake service starts with

Increased speed and accuracy

Hunter's AutoComp Elite® on-vehicle brake lathe compensates in under 12 seconds, on average, using direct compensation. Other methods may take up to two minutes using wandering compensation.

Automatic Compensation enhances speed and accuracy by calculating the exact position of the compensation plates to eliminate guesswork. Direct compensation exceeds the most stringent OE requirements and can make as many as 5 adjustments in a single revolution.

Superior performance features

Easily service difficult vehicles


Service rotors in half the time

The Variable-Speed Drive System allows technicians to resurface rotors at the fastest possible speed without sacrificing quality. Variable speed also means the ACE lathe can avoid locking differentials on trucks and performance vehicles.

Don't remove drive train components

Cut rotors on vehicles that have high driveline drag with reverse rotation and an industry leading 1.5-hp motor, making trucks and performance vehicles easy tasks. Helping you avoid adding time to the job and the risk of removing drive train components!

Watch how to avoid locking differentials

Digi-Cal measurement

Instantly measure rotor dimensions and depth of cut

Digi-Cal arm

Measuring system is located in housing on the end of the cutter shaft.


Bright LED light puts light where you need it - on the backside of the rotor.

Does not lose calibration when turned off or stored.

Easy viewing with Digi-Cal screen
