The Ranger RL-8500 Combination Brake Lathe is intended 

to resurface disc brake rotors, brake drums and flywheels 

on passenger cars, medium duty trucks only. Using this 

lathe for other purposes could result in personal injury and/

or equipment damage.

Cutting Edge Design Features:

• Rather than mechanically driven transmission and gear 

boxes, the RL8500 uses precision electric DC servo motors 

designed to meet the demanding requirements of industrial 

motion control.

• Our Quick Change Adapter Plus system eliminates the 

need for conventional bell clamps and cones and features 

built in springs so you don’t lose them. Works on foreign 

and domestic car and truck hubless drums and rotors 2 

5/32” to 4” center hole and composite rotors 4”to 6 1/4” 

center hole.

• The RL8500 is equipped with features that help increase 

your service capability, like precision twin cutter tools and a 

quick drum to rotor changeover.

• Infinitely variable spindle and cross feed speed settings 

allow for quick rough and precision finish cuts. Simple 

ergonomic controls are designed for minimal operator 

movement.

• The RL8500 maintains accuracy year after year thanks 

to rugged construction like a forged, hardened and 

precision ground spindle that resists grooving and 

eliminates the need for boots. Massive tapered spindle 

bearings offer superior weight support during rotation.

• Our exclusive “splash lube” oil feed system supplies a 

constant flow of oil to the bearings making sure they provide 

years of trouble free service.

• Serpentine belts provide a faster, quieter operation and 

reduce chatter and vibration.

• An independent cross feed motor eliminates the need 

for plastic or bronze shear gears which are expensive and 

timely to replace.

• A convenient top storage tray means your popular 

adapters and tools are kept within easy reach.

• Separate motors on the drum and rotor feed help 

maximize the main motor’s efficiency.

• Our deluxe standard adapter package includes a Quick 

Change hubless adapter system that makes mounting 

rotors and drums quick and easy. A variety of adapters lets 

you machine all standard and composite rotors for foreign 

and domestic cars and light trucks. Optional truck adapter 

kit available.

• A 450 pound cast iron body and a solid work bench 

eliminates transient vibrations ensuring a smooth 

uninterrupted surface finish with each pass.

• Easily change arbor speeds in seconds. Choose 150 or 

250 RPM depending on the job.

• Positive rake cutter tip angle provides for a one pass 

finish virtually every time.
