The AutoComp Elite® at Laura Ford
Laura Ford in Sullivan, MO uses Hunter's AutoComp Elite® On-Car Brake Lathe to help service a wide variety of vehicles at their dealership. They've tried other on-car lathes in the past, but chose the ACE Lathe for easier setup, faster automatic compensation, faster cutting, and its superior surface finish.
AutoComp Elite™ Automatic Compensation Brake Lathe
The AutoComp Elite® brake lathe features automatic compensation technology. The patent pending automatic compensation system directly determines the position of the internal plates to maximize speed and accuracy without operator intervention. The result is the fastest, highest quality brake job possible.
How ACT Works
An in-depth explination on how Hunter Engineering’s Anti-Chatter Technology (ACT) works on Hunter's BL Series Bench Lathe and the on-car lathe, AutoComp Elite®. This technology provides better brake rotor surface finish while also allowing the lathe to cut much faster.
The Benefits of On-Car Brake Lathes
This video explores the causes of vehicle brake shudder and explains why resurfacing rotors on the vehicle provides a better, longer lasting brake job.

Anti-Chatter Technology
Stop chatter before it starts with Anti-Chatter Technology
Anti-Chatter Technology varies the spindle speed to keep chatter-inducing vibration from starting, resulting in a smooth finish.
When machining at a fixed-speed, chatter can start almost immediately. Once that happens, it is already too late; the surface has been ruined.
ACT eliminates the need for hazardous bands, clips or silencer belts needed to control vibration.

Better brake service starts with
Increased speed and accuracy

Hunter's AutoComp Elite® on-car brake lathe compensates in under 12 seconds, on average, using direct compensation. Other methods may take up two minutes using wandering compensation.
Automatic Compensation enhances speed and accuracy by calculating the exact position of the compensation plates to eliminate guess work. 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!
Digi-Cal measurement
Instantly measure drum or rotor dimensions and depth of cut

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.

Customer stories

Brakes Plus
Denver, COOnce I put this lathe into service in a store, the technicians are more likely to use the AutoComp Elite® vs. ‘Brand X’ as they have so much more confidence in what the finished product will be.
Tim Smith - Equipment Manager/Store Inspector, Brakes Plus

BMW of Freehold
Freehold, NJI can’t stress enough the time-savings that we are seeing with this machine. It takes about half as much time to learn and with a team of 25 technicians, I need an on-car brake lathe that is easy to learn and operate.
