Tech Tip: Using An On-Vehicle Brake Lathe On Honda, Hyundai, Mazda And Volkswagen Vehicles

Technical Service Bulletins provided by Honda, Hyundai, Mazda and Volkswagen address the issue of brake pulsation and stress the use of the on-vehicle brake lathe exclusively for rotor resurfacing. They no longer recommend any off-vehicle rotor machining.

Subject: Importance of On-Vehicle Brake Lathe Use

Vehicle Involved: All Late-Model Vehicles

Condition: Vehicles prone to brake pulsation

Repair Procedure: Whether performing a brake job or solving a customer complaint, brake pulsation is an increasing problem for late-model vehicles. Not only in the aftermarket, this problem affects the OE vehicle manufacturers and dealer service departments as well.

OEMs have ample resources for identifying problems and providing solutions for their customers’ satisfaction. Technical Service Bulletins provided by Honda, Hyundai, Mazda and Volkswagen address the issue of brake pulsation and stress the use of the on-vehicle brake lathe exclusively for rotor resurfacing. They no longer recommend any off-vehicle rotor machining.

The reason for this is to account for the runout in the rotor, hub flange, wheel bearings and the surface condition of the mating surfaces of the hub flange and rotor. The goal is to achieve .002” lateral runout or less, as installed on the vehicle.

Axle Torque Procedures

Guessing the correct torque setting is a bad idea.

The physics of all threaded fasteners are the same. As the bolt and nut are turned, the spiral threads convert rotational force into a linear force that creates clamping loads. When a threaded fastener is tightened, it stretches. Since metal is elastic, even greater clamping loads are generated. The threads also generate friction that keeps the assembly together. This especially applies to wheel bearings and axle nuts.
