Cutting-Edge Brake Lathes by Ranger

A brake lathe resurfaces brake rotors and drums by machining away a small amount of material to create a smooth, even friction surface. Correcting surface irregularities and thickness variations can help address brake vibration, pedal pulsation, noise, and uneven braking when the component remains within the manufacturer's allowable service specifications.

A combination brake lathe is designed to machine both disc brake rotors and brake drums on a single machine. Ranger's RL-8500 and RL-8500XLT can quickly transition between rotor and drum resurfacing, allowing repair shops to handle a broader range of brake service without requiring separate machines.

Resurfacing may be appropriate when a rotor or drum has surface irregularities, scoring, glazing, thickness variation, or other conditions that can be safely corrected through machining. Before resurfacing, technicians should always inspect and measure the component to confirm it will remain within the vehicle manufacturer's minimum thickness, maximum diameter, and other service specifications after machining.

Yes. Variations in the rotor friction surface can contribute to brake pedal pulsation and vibration. When the rotor is otherwise serviceable, properly machining the friction surfaces can restore a smoother, more uniform surface and help correct these symptoms.

It depends on the condition and specifications of the rotor. Resurfacing can be a practical option when a rotor has sufficient remaining material and can be machined within manufacturer specifications. Rotors that are too thin, severely damaged, cracked, excessively corroded, or otherwise outside allowable specifications should be replaced rather than resurfaced.

Both are professional combination disc and drum brake lathes that use independent DC servo motors for the cross-feed and spindle-feed drives. The RL-8500XLT adds an extended-capacity spindle and can accommodate brake drums up to 10 inches deep, making it better suited for heavier brake components and expanded service applications.

The RL-8500 and RL-8500XLT use independent DC servo motors to control their cross-feed and spindle-feed drives instead of relying on complex mechanical gearboxes and transmissions. This design reduces mechanical complexity and helps minimize vibration and chatter that could negatively affect the machined surface finish.

Vibration and chatter can transfer through the cutting tool and create imperfections in the finished rotor or drum surface. A stable machining process helps produce a smoother, more consistent finish, which is important for proper brake pad contact and braking performance. Ranger's transmission-free drive design is engineered to reduce potential sources of vibration during machining.

Yes. The Ranger RL-8500 and RL-8500XLT are designed for resurfacing compatible rotors, drums, and flywheels when used with the appropriate tooling and adapters. Always verify component dimensions and machine compatibility before beginning a machining operation.

Yes. Ranger offers optional light- and medium-truck adapters for the RL-8500 and RL-8500XLT. These adapters expand mounting capability for compatible truck rotors, drums, and flywheels while incorporating additional mass and vibration damping to help produce a smooth surface finish.

An adjustable feed rate lets the technician control how quickly the cutting tool travels across the rotor or drum surface. Ranger brake lathes provide continuously adjustable feed settings, allowing faster feed rates for initial rough cuts and slower settings when a finer surface finish is desired.

Ranger brake lathes are well suited for automotive repair shops, brake specialists, dealerships, fleet maintenance facilities, municipal garages, and other operations that regularly perform brake service. Bringing rotor and drum resurfacing in-house can give shops greater control over turnaround times while expanding their brake service capabilities.

Ranger brake lathes combine a time-tested, heavy-duty design with modern DC servo feed controls, adjustable cutting speeds, quick drum-to-rotor changeover, and comprehensive tooling. With the RL-8500 for professional brake service and the extended-capacity RL-8500XLT for heavier applications, shops can choose a machine suited to their workload while gaining the ability to resurface rotors, drums, and compatible flywheels in-house.
